Accounting Policies [Abstract] | |
Summary of accounting policies | 1. Summary of accounting policies: Description of business— Nomura Holdings, Inc. (“Company”) and its broker-dealer, banking and other financial services subsidiaries provide investment, financing and related services to individual, institutional and government clients on a global basis. The Company and other entities in which it has a controlling financial interest are collectively referred to as “Nomura” within these consolidated financial statements. Nomura operates its business through various divisions based upon the nature of specific products and services, its main client base and its management structure. On April 1, 2021, the Asset Management Division and the Merchant Banking Division were combined and the Investment Management Division was established. Nomura reports operating results through three business segments: Retail, Investment Management, and Wholesale. In its Retail segment, Nomura provides investment consultation services mainly to individual clients in Japan. In its Investment Management segment, Nomura mainly provides various investment management services and investment solutions such as establishing and managing investment trusts, discretionary investment services for domestic and overseas investors, investment and management for investment corporation and for funds for institutional investors, and management of Tokumei kumiai (silent partnerships). In its Wholesale segment, Nomura engages in the sales and trading of debt and equity securities, foreign exchange contracts and derivatives globally, and provides investment banking services such as the underwriting and distribution of debt and equity securities as well as mergers and acquisitions and financial advisory. Basis of presentation— The accounting and financial reporting policies of Nomura conform to accounting principles generally accepted in the United States (“U.S. GAAP”) as applicable to broker-dealers. These consolidated financial statements include the financial statements of the Company and other entities in which it has a controlling financial interest. Nomura initially determines whether it has a controlling financial interest in an entity by evaluating whether the entity is a variable interest entity (“VIE”) under Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 810 “ Consolidation For entities other than VIEs, Nomura is generally determined to have a controlling financial interest in an entity when it owns a majority of the voting interests. Equity investments in entities in which Nomura has significant influence over operating and financial decisions (generally defined as a holding of 20 to 50 percent of the voting stock of a corporate entity, or at least 3 percent of a limited partnership) are accounted for under the equity method of accounting (“equity method investments”) and reported within Other assets — Investments in and advances to affiliated companies Financial Instruments Trading assets, Private equity and debt investments or Other assets — Other Equity investments in which Nomura has neither control nor significant influence are carried at fair value, with changes in fair value recognized through the consolidated statements of income and reported within Trading assets, Private equity and debt investments or Other assets — Other Certain consolidated entities are investment companies under ASC 946 “ Financial Services — Investment Companies The Company’s principal subsidiaries include Nomura Securities Co., Ltd. (“NSC”), Nomura Securities International, Inc. (“NSI”), Nomura International plc (“NIP”) and Nomura Financial Products & Services, Inc. (“NFPS”). All material intercompany transactions and balances have been eliminated on consolidation. Use of estimates— Nomura uses accounting estimates to prepare these consolidated financial statements and they require difficult, subjective and complex judgments by management. Such estimates determined by management to be material include estimates regarding the fair value of financial instruments and litigation provisions. Estimates, by their nature, are based on underlying assumptions which require management judgment and depend on the extent of available information. Actual results in future periods may differ from current estimates, which could have a material impact on these consolidated financial statements. Various references are made throughout the notes to these consolidated financial statements where critical accounting estimates based on management judgment have been made, the nature of the estimates, the underlying assumptions made by management used to derive those estimates and how these estimates affect the amounts reported in these consolidated financial statements. Fair value of financial instruments— A significant amount of Nomura’s financial assets and financial liabilities are carried at fair value, with changes in fair value recognized through the consolidated statements of income and/ or the consolidated statements of comprehensive income. Use of a fair value measurement is either specifically required under U.S. GAAP or Nomura makes an election to use a fair value measurement for certain eligible items under the fair value option. Other financial assets and financial liabilities are carried at fair value on a nonrecurring basis, where the primary measurement basis is not fair value. Fair value is only used in specific circumstances after initial recognition, such as to measure impairment. In both cases, fair value is generally determined in accordance with ASC 820 “ Fair Value Measurements and Disclosures Fair value measurements The fair values of financial assets and financial liabilities of consolidated VIEs which meet the definition of collateralized financing entities are both measured using the more observable fair value of the financial assets and financial liabilities. Allowance for current expected credit losses— Management recognizes allowance for current expected credit losses on financial assets not carried at fair value and certain off-balance “Financial Instruments – Credit Losses” Current expected credit losses are calculated over the expected life of the financial instruments in scope of the requirements on an individual or a portfolio basis, considering all relevant, reasonable and supportable information available about the collectability of cash flows, including information about past events, current conditions and future forecasts. Accrued interest receivables are excluded from the amortized cost basis of financing receivables when calculating current expected credit losses. The methodology used by Nomura to determine allowances for current expected credit losses in accordance with the current expected credit losses impairment model (“CECL impairment model”) primarily depends on the nature of the financial instrument and whether certain practical expedients permitted by ASC 326 are applied by Nomura. Allowances for current expected credit losses against recognized financial instruments are reported in the consolidated balance sheets within Allowance for credit losses off-balance Other liabilities Other expenses. See Note 7 “Financing receivables” Transfers of financial assets— Nomura accounts for the transfer of a financial asset as a sale when Nomura relinquishes control over the asset by meeting the following conditions: (a) the asset has been isolated from the transferor (even in bankruptcy or other receivership), (b) the transferee has the right to pledge or exchange the asset received, or if the transferee is an entity whose sole purpose is to engage in securitization or asset-backed financing activities, if, the holders of its beneficial interests have the right to pledge or exchange the beneficial interests held and (c) the transferor has not maintained effective control over the transferred asset. In connection with its securitization activities, Nomura utilizes special purpose entities (“SPEs”) to securitize commercial and residential mortgage loans, government and corporate securities or other types of financial assets. Nomura’s involvement with SPEs includes structuring and underwriting, distributing and selling debt instruments and beneficial interests issued by SPEs to investors. Nomura derecognizes financial assets transferred in securitizations provided that Nomura has relinquished control over such assets and does not consolidate the SPE. Nomura may obtain or retain an interest in the financial assets, including residual interests in the SPEs dependent upon prevailing market conditions. Any such interests are carried at fair value and reported within Trading assets Revenue —Net gain on trading Foreign currency translation— The financial statements of the Company’s subsidiaries and operations are measured using their functional currency which is the currency of the primary economic environment in which the entity operates. All assets and liabilities of subsidiaries and operations which have a functional currency other than Japanese Yen are translated into Japanese Yen at exchange rates at the balance sheet date, and all revenue and expenses are translated at the average exchange rates for the respective years and the resulting translation adjustments are reported within Accumulated other comprehensive income (loss) Foreign currency assets and liabilities are translated at exchange rates at the balance sheet date and the resulting translation gains or losses are credited or charged to the consolidated statements of income. Revenue from services provided to customers— Nomura earns revenue through fees and commissions from providing financial services to customers across all three business divisions. These services primarily include trade execution and clearing services, distribution of fund unit services, financial advisory services, underwriting and distribution services and asset management services. Revenue is recognized when or as the client obtains control of the service provided by Nomura which depends on when each of the key distinct substantive promises made by Nomura within the contract with the client (“performance obligations”) are satisfied. Such performance obligations are generally satisfied at a particularly point in time or, if certain criteria are met, over a period of time. Revenue from providing distribution of fund units and clearing services is reported in the consolidated statements of income within Revenue — Commissions, Revenue — Asset management and portfolio service fees Revenue — Fees from investment banking Costs to obtain or fulfill the underlying contract to provide services to a client are deferred as assets if certain criteria are met. These deferred costs, which are reported in the consolidated balance sheets within Other assets impaired Trading assets and trading liabilities— Trading assets Financial assets are classified as being held for trading when any of the following criteria are met: • The financial assets are originated or acquired with the intention to generate profit through sale in the short-term; • The financial assets are part of a portfolio of identified financial instruments that are managed together for the purposes of short-term profit or arbitrage profit-taking; or • The financial assets are derivative assets. Trading liabilities Revenue — Net gain on trading Certain nonderivative trading liabilities are held to economically hedge the price risk of specific investments in equity securities held for operating purposes. Changes in fair value of these trading liabilities are reported within Revenue—Gain (loss) on investments in equity securities the Collateralized agreements and collateralized financing— Collateralized agreements Securities purchased under agreements to resell Securities borrowed Collateralized financing Securities sold under agreements to repurchase Securities loaned Reverse repurchase and repurchase agreements principally involve the buying or selling of securities under agreements with clients to resell or repurchase these securities to or from those clients, respectively. These transactions are generally accounted for as collateralized agreements or collateralized financing transactions and are recognized in the consolidated balance sheets at the amount for which the securities were originally acquired or sold. Certain reverse repurchase and repurchase agreements are carried at fair value through election of the fair value option. Nomura also enters into Gensaki Repo transactions which are the standard type of repurchase agreement used in Japanese financial markets. Gensaki Repo transactions contain margin requirements, rights of security substitution, and certain restrictions on the client’s right to sell or repledge the transferred securities. Gensaki Repo transactions are accounted for as collateralized agreements or collateralized financing transactions and are recognized on the consolidated balance sheets at the amount that the securities were originally acquired or sold. Securities borrowing and lending transactions are generally accounted for as collateralized agreements and collateralized financing transactions, respectively. These transactions are generally cash collateralized and are recognized on the consolidated balance sheets at the amount of cash collateral advanced or received. Allowances for current expected credit losses recognized against securities borrowing transactions are not significant due to an ongoing monitoring of collateral and the short expected life of these transactions. Where Nomura acts as lenders in securities borrowing and lending transactions and receives securities that can be sold or pledged as collateral, Nomura recognizes the securities received at fair value within Other assets — Other Other liabilities. See Note 7 “Financing receivables” Offsetting of collateralized agreements and collateralized financings Reverse repurchase agreements and repurchase agreements (including Gensaki Repo transactions) accounted for as collateralized agreements and collateralized financing transactions, respectively, entered into with the same counterparty and documented under a master netting agreement are offset in the consolidated balance sheets where the specific criteria defined by ASC 210-20 Balance Sheet —Offsetting 210-20”) close-out 210-20 Other secured borrowings Trading balances of secured borrowings Transfers and Servicing Long-term borrowings “Securitizations and Variable Interest Entities” “Borrowings” All Nomura-owned assets pledged to counterparties where the counterparty has the right to sell or repledge the securities, including collateral transferred under Gensaki Repo transactions, are reported parenthetically within Trading assets as Assets pledged See Note 5 “Collateralized transactions” Derivatives— Nomura uses a variety of derivatives, including futures, forwards, swaps and options, for both trading and non-trading Trading assets or Trading liabilities Short-term borrowings or Long-term borrowings Derivatives used for trading purposes Derivatives used for trading purposes, including bifurcated embedded derivatives, are carried at fair value with changes in fair value reported in the consolidated statements of income within Revenue — Net gain on trading Derivatives held for non-trading In addition to its trading activities, Nomura uses derivatives for other than trading purposes such as to manage risk exposures arising from recognized assets and liabilities, forecasted transactions and firm commitments. Derivatives held for non-trading Derivatives and Hedging Fair value hedges Nomura designates certain derivative as fair value hedges of interest rate risk and foreign exchange risk arising from specific financial liabilities and foreign currency denominated non-trading Interest expense Revenue — Other Net investment hedges Nomura designates certain derivatives as hedges of the net investment in foreign operations related to specific subsidiaries with non-Japanese Revenue — Other Accumulated other comprehensive income (loss) Economic expense hedges Nomura designates certain derivatives as economic expense hedges to manage equity price risk or foreign currency risk of certain expenses arising from forecasted transactions or firm commitments. Changes in fair value of these derivatives are reported in the same line item in the consolidated statements of income where expenses arising from the hedged transactions are reported. Offsetting of derivatives Derivative assets and liabilities with the same counterparty documented under a legally enforceable master netting agreement and the related cash collateral receivables and payables are presented on a net basis in the consolidated balance sheets where the specific criteria defined by ASC 210-20 Settlement-to-market Exchange traded and centrally cleared OTC derivatives typically involve daily variation margin payments and receipts which reflect changes in the fair value of the related derivatives. Such variation margin amounts are accounted for as either a partial settlement of the derivative or as a separate cash collateral receivable or payable depending on the legal form of the arrangement with the relevant central clearing counterparty. See Note 3 “ Derivatives and hedging activities Loans receivable— Loans receivable are loans which management intends to hold for the foreseeable future. Loans receivable are either carried at fair value or at amortized cost. Interest earned on loans receivable is reported in the consolidated statements of income within Revenue — Interest and dividends Loans receivable carried at fair value Certain loans which are risk managed on a fair value basis are carried at fair value through election of the fair value option. Nomura makes this election to mitigate volatility in the consolidated statements of income caused by the difference in measurement basis that would otherwise exist between the loans and the derivatives used to risk manage those loans. Changes in the fair value of loans receivable carried at fair value are reported in the consolidated statements of income within Revenue — Net gain on trading Loans receivable carried at amortized cost Loans receivable which are not carried at fair value are carried at amortized cost. Amortized cost represents cost adjusted for deferred fees and direct costs, unamortized premiums or discounts on purchased loans and after deducting applicable allowances for current expected credit losses under ASC 326 which Nomura initially adopted from April 1, 2020. Loan origination fees, net of direct origination costs, are amortized to Revenue — Interest and dividends Modifications of loans receivable where the borrower is in financial difficulty and Nomura has granted a financial concession are typically accounted for as troubled debt restructurings (“TDRs”). See Note 7 “ Financing receivables Other receivables— Receivables from customers Receivables from other than customers These amounts are carried at contractual amounts due less any applicable allowance for current expected credit losses recognized under ASC 326. See Note 7 “ Financing receivables” Loan commitments— Unfunded loan commitments written by Nomura are accounted for as either off-balance These loan commitments are generally accounted for in a manner consistent with the accounting for the loan receivable upon funding. Where the loan receivable will be classified as a trading asset or will be elected for the fair value option, the loan commitment is also generally carried at fair value, with changes in fair value reported in the consolidated statements of income within Revenue — Net gain on trading For loan commitments where the loan will be held for the foreseeable future and will not be elected for the fair value option, Nomura recognizes allowances for current expected credit losses in accordance with ASC 326. Loan commitment fees are generally deferred and recognized over the term of the loan when funded as an adjustment to yield. If drawdown of the loan commitment is considered remote, loan commitment fees are recognized over the commitment period as service revenue. See Note 7 “Financing receivables” Payables and deposits— Payables to customers Payables to other than customers failed-to-receive Deposits received at banks Office buildings, land, equipment and facilities— Office buildings, land, equipment and facilities, owned and held for use by Nomura are stated at cost, net of accumulated depreciation and amortization, except for land, which is stated at cost. Significant renewals and additions are capitalized at cost. Maintenance, repairs and minor renewals are expensed as incurred in the consolidated statements of income. Leases and subleases entered into by Nomura as either lessor or lessee are classified as either operating or finance leases on inception date in accordance with ASC 842 “Leases”. right-of-use Other assets—Office buildings, land, equipment and facilities Other liabilities Lease liabilities are initially measured at present value of the future minimum lease payments over the expected lease term. The future minimum lease payments are discounted using a relevant Nomura incremental borrowing rate as derived from information available at lease commencement date. The expected lease term is generally determined based on the contractual maturity of the lease, and adjusted for periods covered by options to extend or terminate the lease when Nomura is reasonably certain to exercise those options. ROU assets are initially measured at the amount of lease liabilities, and adjusted for any prepaid lease payments, initial direct costs incurred and any lease incentives received. After lease commencement date, for operating leases Nomura as lessee recognizes lease expense over the lease term generally on a straight-line basis within Occupancy and related depreciation Information processing and communications Depreciation and amortization charges of owned assets are generally computed using the straight-line method and recognized over the estimated useful lives of each asset. The estimated useful life of an asset takes into consideration technological change, normal deterioration and actual physical usage by Nomura. Leasehold improvements are depreciated over the shorter of their useful life or the term of corresponding lease. The estimated useful lives for significant asset classes are as follows: Office buildings 3 to 50 years Equipment and facilities 3 to 20 years Software 3 to 10 years Long-lived assets, including ROU assets and software assets but excluding goodwill and indefinite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the estimated future undiscounted cash flows generated by the asset is less than the carrying amount of the asset, a loss is recognized to the extent that the carrying value exceeds its fair value. See Note 8 “ Leases Investments in equity securities— Nomura holds minority stakes in the equity securities of unaffiliated Japanese financial institutions and corporations in order to promote existing and potential business relationships. These companies often have similar investments in Nomura. Such cross-holdings are a customary business practice in Japan and provide a way for companies to manage shareholder relationships. These investments, which Nomura refers to as being held for operating purposes, are carried at fair value and reported within Other assets — Investments in equity securities Revenue — Gain (loss) on investments in equity securities Other non-trading Certain subsidiaries within Nomura hold debt securities and minority stakes in equity securities for non-trading Non-trading Other assets — Non-trading Other assets — Other Revenue — Other non-trading Revenue — Other Short-term and long-term borrowings— Short-term borrowings are defined as borrowings which are due on demand, which have a contractual maturity of one year or less at issuance date, or which have a longer contractual maturity but which contain substantive features outside of Nomura’s control that allows the investor to demand redemption within one year from original issuance date, provided exercise of such features are not considered to be remote. Short-term and long-term borrowings primarily consist of commercial paper, bank borrowings, and certain structured notes issued by Nomura and SPEs consolidated by Nomura, and financial liabilities recognized in transfers of financial assets which are accounted for as financings rather than sales under ASC 860 (“secured financing transactions”). Of these financial liabilities, certain structured notes and secured financing transactions are accounted for at fair value on a recurring basis through election of the fair value option. Other short and long-term borrowings are carried at amortized cost. Structured notes are debt securities which contain embedded features (often meeting the accounting definition of a derivative) that alter the return to the investor from simply receiving a fixed or floating rate of interest to a return that depends upon some other variable(s) such as an equity or equity index, commodity price, foreign exchange rate, credit rating of a third party or more complex interest rate calculation. Structured borrowings are borrowings that have similar characteristics as structured notes. All structured notes and certain structured borrowings issued by Nomura are carried at fair value on a recurring basis through election of the fair value option. This blanket election for structured notes and certain structured borrowings are made primarily to mitigate the volatility in the consolidated statements of income caused by differences in the measurement basis for structured notes and the derivatives used to risk manage those positions and to generally simplify the accounting Nomura applies to these financial instruments. Changes in the fair value of structured notes elected for the fair value option are reported within Revenue — Net gain on trading Other comprehensive income See Note 10 “ Borrowings Income taxes— Deferred tax assets and liabilities are recognized to reflect the expected future tax consequences of operating loss carryforwards, tax credit carryforwards and temporary differences between the carrying amounts for financial reporting purposes and the tax bases of assets and liabilities based upon enacted tax laws and tax rates. Nomura recognizes deferred tax assets to the extent it believes that it is more likely than not that a benefit will be realized. A valuation allowance is established against deferred tax assets for tax benefits available to Nomura that are not deemed more likely than not to be realized. Deferred tax assets and deferred tax liabilities that relate to the same tax-paying Other assets — Other Other liabilities Nomura recognizes and measures unrecognized tax benefits based on Nomura’s estimate of the likelihood, based on technical merits, that tax positions will be sustained upon examination based on the facts and circumstances and information available at the end of each reporting period. Nomura adjusts the level of unrecognized tax benefits when there is more information available, or when an event occurs requiring a change. The reassessment of unrecognized tax benefits could have a material impact on Nomura’s effective tax rate in the period in which it occurs. Nomura reports income tax-related Income tax expense See Note 1 4 Income taxes Stock-based and other compensation awards— Stock-based awards issued by Nomura to senior management and other employees are classified as either equity or liability awards depending on the terms of the award. Stock-based awards such as Stock Acquisition Rights (“SARs”) and Restricted Stock Units (“RSUs”) which are expected to be settled by the delivery of the Company’s common stock are classified as equity awards. For these awards, total compensation cost is generally fixed at the grant date and measured using the grant-date fair value of the award, net of any amount the employee is obligated to pay and estimated forfeitures. Stock-based awards such as Notional Stock Units (“NSUs”) and Collared Notional Stock Units (“CSUs”) which are expected to be settled in cash are classified as liability awards. Liability awards are remeasured to fair value at each balance sheet date, net of estimated forfeitures with the final measurement of cumulative compensation cost equal to the settlement amount. For both equity and liability awards, fair value is determined either by using option pricing models, the market price of the Company’s common stock or the price of the third party index, as appropriate. Compensation cost is recognized in the consolidated statements of income over the requisite service period, which generally is equal to the contractual vesting period. Where an award has graded vesting, compensation expense is recognized using the accelerated recognition method. Certain deferred compensation awards include “Full Career Retirement” (“FCR”) provisions which permit recipients of the awards to continue to vest in the awards upon voluntary termination or by claiming FCR during a pre-defined See Note 1 3 Deferred compensation awards Earnings per share— The computation of basic earnings per share is based on the weighted average number of shares outstanding during the year. Diluted earnings per share reflects the assumed conversion of all dilutive securities based on the most advantageous conversion rate or exercise price available to the investors, and assuming conversion of convertible debt under the if-converted See Note 1 1 Earnings per share Cash and cash equivalents— Nomura defines cash and cash equivalents as cash on hand and demand deposits with banks. Goodwill and intangible assets— Goodwill is recognized upon completion of a business combination as the difference between the purchase price and the fair value of the net assets acquired. Subsequent to initial recognition, goodwill is not amortized but is tested for impairment at a reporting unit level during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Nomura’s reporting units are at the same level as or one level below its business segments. Nomura tests goodwill of each separate reporting unit by initially qualitatively assessing whether events and circumstances indicate that it is more likely than not (i.e., greater than 50% likelihood) that a reporting unit’s fair value is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the reporting unit is deemed not to be impaired and no further analysis is required. If it is more likely than not that fair value of the reporting unit is below its carrying value, a quantitative test is then performed. A goodwill impairment loss is recognized through the consolidated statements of income as the excess of the carrying amount of a reporting unit, including goodwill, over its fair value but limited to the total amount of goodwill allocated to the reporting unit. Intangible assets not subject to amortization (“indefinite-lived intangible assets”) are tested for impairment on an individual asset basis during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Similar to goodwill, Nomura tests an indefinite-lived intangible asset by initially qualitatively assessing whether events or circumstances indicate that it is more likely than not that the fair value of the intangible asset is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the intangible asset is deemed not to be impaired and no further analysis is required. If it is more likely than not that the fair value of the intangible asset is below its carrying value, the current estimated fair value of the intangible asset is compared with its carrying value. An impairment loss is recognized if the carrying value of the intangible asset exceeds its estimated fair value. Intangible assets with finite lives (“finite-lived intangible assets”) are amortized over their estimated useful lives and tested for impairment either individually or with other assets (“asset group”) when events and circumstances indicate that the carrying value of the intangible asset (or asset group) may not be recoverable. A finite-lived intangible asset is impaired when its carrying amount or the carrying amount of the asset group exceeds its fair va |

Fair value measurements | 2. Fair value measurements: The fair value of financial instruments A significant amount of Nomura’s financial instruments are carried at fair value. Financial assets carried at fair value on a recurring basis are reported in the consolidated balance sheets within Trading assets and private equity and debt investments, Loans and receivables, Collateralized agreements Other assets Trading liabilities, Short-term borrowings, Payables and deposits, Collateralized financing, Long-term borrowings Other liabilities. Other financial assets and financial liabilities are carried at fair value on a nonrecurring basis, where the primary measurement basis is not fair value but where fair value is used in specific circumstances after initial recognition, such as to measure impairment. In all cases, fair value is determined in accordance with ASC 820 “ Fair Value Measurements and Disclosures Fair value is usually determined on an individual financial instrument basis consistent with the unit of account of the financial instrument. However, certain financial instruments managed on a portfolio basis are valued as a portfolio, namely based on the price that would be received to sell a net long position (i.e., a net financial asset) or transfer a net short position (i.e., a net financial liability) consistent with how market participants would price the net risk exposure at the measurement date. Financial assets carried at fair value also include investments in certain funds where, as a practical expedient, fair value is determined on the basis of net asset value per share (“NAV per share”) if the NAV per share is calculated in accordance with certain industry standard principles. Increases and decreases in the fair value of assets and liabilities may significantly impact Nomura’s position, performance, liquidity and capital resources. As explained below, valuation techniques applied contain inherent uncertainties and Nomura is unable to predict the accurate impact of future developments in the market. The valuation of financial instruments is more difficult during periods of market stress as a result of greater volatility and reduced price transparency, such as during the COVID-19 economic hedging strategies to mitigate risk, although these hedges are also subject to unpredictable movements in the market. Valuation methodology for financial instruments carried at fair value on a recurring basis The fair value of financial instruments is based on quoted market prices including market indices, broker or dealer quotations or an estimation by management of the expected exit price under current market conditions. Various financial instruments, including cash instruments and over-the-counter bid-offer Where quoted prices are available in active markets, no valuation adjustments are taken to modify the fair value of assets or liabilities marked using such prices. Other instruments may be measured using valuation techniques, such as valuation pricing models incorporating observable valuation inputs, unobservable parameters or a combination of both. Valuation pricing models use valuation inputs which would be considered by market participants in valuing similar financial instruments. Valuation pricing models and their underlying assumptions impact the amount and timing of unrealized and realized gains and losses recognized, and the use of different valuation pricing models or underlying assumptions could produce different financial results. Valuation uncertainty results from a variety of factors, including the valuation technique or model selected, the quantitative assumptions used within the valuation model, the inputs into the model, as well as other factors. Valuation adjustments are used to reflect the assessment of this uncertainty. Common valuation adjustments include model reserves, credit adjustments, close-out The level of adjustments is largely judgmental and is based on an assessment of the factors that management believe other market participants would use in determining the fair value of similar financial instruments. The type of adjustments taken, the methodology for the calculation of these adjustments, and the valuation inputs for these calculations are reassessed periodically to reflect current market practice and the availability of new information. For example, the fair value of certain financial instruments includes adjustments for credit risk, both with regards to counterparty credit risk on positions held and Nomura’s own creditworthiness on positions issued. Credit risk on financial assets is significantly mitigated by credit enhancements such as collateral and netting arrangements. Any net credit exposure is measured using available and applicable valuation inputs for the relevant counterparty. The same approach is used to measure the credit exposure on Nomura’s financial liabilities as is used to measure counterparty credit risk on Nomura’s financial assets. Such valuation pricing models are calibrated to the market on a regular basis and inputs used are adjusted for current market conditions and risks. The Valuation Model Validation Group within Nomura’s Risk Management Department reviews pricing models and assesses model appropriateness and consistency independently of the front office. The model reviews consider a number of factors about a model’s suitability for valuation and sensitivity of a particular product. Valuation models are calibrated to the market on a periodic basis by comparison to observable market pricing, comparison with alternative models and analysis of risk profiles. As explained above, any changes in fixed income, equity, foreign exchange and commodity markets can impact Nomura’s estimates of fair value in the future, potentially affecting trading gains and losses. Where financial contracts have longer maturity dates, Nomura’s estimates of fair value may involve greater subjectivity due to the lack of transparent market data. Fair value hierarchy All financial instruments carried at fair value, including those carried at fair value using the fair value option, have been categorized into a three-level hierarchy (“fair value hierarchy”) based on the transparency of valuation inputs used by Nomura to estimate fair value. A financial instrument is classified in the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement of the financial instrument. The three levels of the fair value hierarchy are defined as follows, with Level 1 representing the most transparent inputs and Level 3 representing the least transparent inputs: Level 1: Observable valuation inputs that reflect quoted prices (unadjusted) for identical financial instruments traded in active markets at the measurement date. Level 2: Valuation inputs other than quoted prices included within Level 1 that are either directly or indirectly observable for the financial instrument. Level 3: Unobservable valuation inputs which reflect Nomura assumptions and specific data. The availability of valuation inputs observable in the market varies by product and can be affected by a variety of factors. Significant factors include, but are not restricted to the prevalence of similar products in the market, especially for customized products, how established the product is in the market, for example, whether it is a new product or is relatively mature, and the reliability of information provided in the market which would depend, for example, on the frequency and volume of current data. A period of significant change in the market may reduce the availability of observable data. Under such circumstances, financial instruments may be reclassified into a lower level in the fair value hierarchy. Significant judgments used in determining the classification of financial instruments include the nature of the market in which the product would be traded, the underlying risks, the type and liquidity of market data inputs and the nature of observed transactions for similar instruments. Where valuation models include the use of valuation inputs which are less observable or unobservable in the market, significant management judgment is used in establishing fair value. The valuations for Level 3 financial instruments, therefore, involve a greater degree of judgment than those valuations for Level 1 or Level 2 financial instruments. Certain criteria used to determine whether a market is active or inactive include the number of transactions, the frequency that pricing is updated by other market participants, the variability of price quotes among market participants, and the amount of publicly available information.

Valuation techniques by major class of financial instrument The valuation techniques used by Nomura to estimate fair value for major classes of financial instruments, together with the significant inputs which determine classification in the fair value hierarchy, are as follows. Equities Other assets Other assets mid-market Private equity and debt investments are also made, in the absence of third-party transactions, if it is determined that the expected exit price of the investment is different from carrying value. In reaching that determination, Nomura primarily uses either a discounted cash flow (“DCF”) or market multiple valuation technique. A DCF valuation technique incorporates estimated future cash flows to be generated from the investee, as adjusted for an appropriate growth rate discounted at a weighted average cost of capital (“WACC”). Market multiple valuation techniques include comparables such as Enterprise Value/Earnings before interest, taxes, depreciation and amortization (“EV/EBITDA”) ratios, Price/Earnings (“PE”) ratios, Price/Book ratios, Price/Embedded Value ratios and other multiples based on relationships between numbers reported in the financial statements of the investee and the price of comparable companies. A liquidity discount may also be applied to either a DCF or market multiple valuation to reflect the specific characteristics of the investee. The liquidity discount includes considerations for various uncertainties in the model and inputs to valuation. Where possible these valuations are compared with the operating cash flows and financial performance of the investee or properties relative to budgets or projections, PE data for similar quoted companies, trends within sectors and/or regions and any specific rights or terms associated with the investment, such as conversion features and liquidation preferences. Private equity and debt investments are generally classified in Level 3 since the valuation inputs such as those mentioned above are usually unobservable. Government, agency and municipal securities Non-G7 non-G7 Bank and corporate debt securities Commercial mortgage-backed securities (“CMBS”) Residential mortgage-backed securities (“RMBS”) comparable securities to classify them in Level 2, or one or more of the significant valuation inputs used in DCF valuations are unobservable. Real estate-backed securities Collateralized debt obligations (“CDOs”) and other Investment trust funds and other Derivatives Equity contracts Derivatives—Interest rate contracts interest rate derivatives which are traded in inactive markets or where the exchange price is not representative of fair value is determined using a model price and are classified in Level 2. The fair value of OTC interest rate derivatives is determined through DCF valuation techniques as well as option models such as Black-Scholes or Monte Carlo simulation. The significant valuation inputs used include interest rates, forward foreign exchange (“FX”) rates, volatilities and correlations. Valuation adjustments are also made to model valuations in order to reflect counterparty credit risk on derivative assets and Nomura’s own creditworthiness on derivative liabilities. OTC interest rate derivatives are generally classified in Level 2 because all significant valuation inputs and adjustments are observable or market-corroborated. Certain less liquid vanilla or more complex OTC interest rate derivatives are classified in Level 3 where interest rate, volatility or correlation valuation inputs are significant and unobservable. Derivatives—Credit contracts Derivatives —Foreign exchange contracts Nomura includes valuation adjustments in its estimation of fair value of certain OTC derivatives relating to funding costs associated with these transactions to be consistent with how market participants in the principal market for these derivatives would determine fair value. Loans and receivables Collateralized agreements Collateralized financing Non-trading non-trading Government, agency and municipal securities Bank and corporate debt securities Short-term long-term borrowings (“Structured notes”) The fair value of structured notes is determined using quoted prices in active markets for the identical instrument if available, and where not available, using a mixture of valuation techniques that use the quoted price of the identical liability when traded as an asset, quoted prices for similar liabilities, similar liabilities when traded as assets, or an internal model which combines DCF valuation techniques and option pricing models, depending on the nature of the embedded features within the structured note. Where an internal model is used, Nomura estimates the fair value of both the underlying debt instrument and the embedded derivative components. The significant valuation inputs used to estimate the fair value of the debt instrument component include yield curves, prepayment rates, default probabilities and loss severities. The significant valuation inputs used to estimate the fair value of the embedded derivative component are the same as those used for the relevant type of freestanding OTC derivative discussed above. A valuation adjustment is also made to the entire structured note in order to reflect Nomura’s own creditworthiness. This adjustment is determined based on recent observable secondary market transactions and executable broker quotes involving Nomura debt instruments and is therefore typically treated as a Level 2 valuation input. Structured notes are generally classified in Level 2 of the fair value hierarchy as all significant valuation inputs and adjustments are observable. Where any unobservable valuation inputs are significant, such as yields, prepayment rates, default probabilities, loss severities, volatilities and correlations used to estimate the fair value of the embedded derivative component, structured notes are classified in Level 3. Long-term borrowings (“Secured financing transactions”) Transfer and Servicing Level 3 financial instruments The valuation of Level 3 financial assets and liabilities is dependent on certain significant valuation inputs which are unobservable. Common characteristics of an inactive market include a low number of transactions of the financial instrument, stale or non-current non-executable If corroborative evidence is not available to value Level 3 financial instruments, fair value may be measured using other equivalent products in the market. The level of correlation between the specific Level 3 financial instrument and the available benchmark instrument is considered as an unobservable valuation input. Other techniques for determining an appropriate value for unobservable valuation input may consider information such as consensus pricing data among certain market participants, historical trends, extrapolation from observable market data and other information Nomura would expect market participants to use in valuing similar instruments. Use of reasonably possible alternative valuation input assumptions to value Level 3 financial instruments will significantly influence fair value determination. Ultimately, the uncertainties described above about input assumptions imply that the fair value of Level 3 financial instruments is a judgmental estimate. The specific valuation for each instrument is based on management’s judgment of prevailing market conditions, in accordance with Nomura’s established valuation policies and procedures. Quantitative and qualitative information regarding significant unobservable valuation inputs The following tables present quantitative and qualitative information about the significant unobservable valuation inputs used by Nomura to measure the fair value of financial instruments classified in Level 3 as of March 31, 2022 and 2023. These financial instruments will also typically include observable valuation inputs (i.e., Level 1 or Level 2 valuation inputs) which are not included in the table and are also often hedged using financial instruments which are classified in Level 1 or Level 2 of the fair value hierarchy. Changes in each of these significant unobservable valuation inputs used by Nomura will impact upon the fair value measurement of the financial instrument. The following tables also illustrate qualitatively how an increase in those significant unobservable valuation inputs might result in a higher or lower fair value measurement at the reporting date and the interrelationship between significant unobservable valuation inputs where more than one is used to determine fair value measurement of the financial instruments.

Derivative Instruments and Hedging Activities [Abstract] | |
Derivative instruments and hedging activities | 3. Derivative instruments and hedging activities: Nomura uses a variety of derivatives, including futures, forwards, options and swaps, for both trading and non-trading Derivatives used for trading purposes In the normal course of business, Nomura enters into transactions involving derivatives to meet client needs, for trading purposes, and to reduce its own exposure to loss due to adverse fluctuations in interest rates, currency exchange rates and market prices of securities. These financial instruments include contractual agreements such as commitments to swap interest payment streams, exchange currencies or purchase or sell securities and other financial instruments on specific terms at specific future dates. Nomura maintains active trading positions in a variety of derivatives. Most of Nomura’s trading activities are client oriented. Nomura utilizes a variety of derivatives as a means of bridging clients’ specific financial needs and investors’ demands in the securities markets. Nomura also actively trades securities and various derivatives to facilitate its clients in adjusting their risk profiles change. In performing these activities, Nomura carries an inventory of capital markets instruments and maintains its access to market liquidity by quoting bid and offer prices to and trading with other market makers. These activities are essential to provide clients with securities and other capital market products at competitive prices. Futures and forward contracts are commitments to either purchase or sell securities, foreign exchange contracts or other capital market instruments at a specific future date for a specified price and may be settled in cash or through delivery. Foreign exchange contracts include spot and forward contracts and involve the exchange of two currencies at a rate agreed by the contracting parties. Risks arise from the possible inability of counterparties to meet the terms of their contracts and from movements in market prices. Futures contracts are executed through exchanges which clear and guarantee performance of counterparties. Accordingly, credit risk associated with futures contracts is considered minimal. In contrast, forward contracts are generally negotiated between two counterparties and, therefore, are subject to counterparty risks. Options are contracts that grant the purchaser, for a premium payment, the right to either purchase or sell a financial instrument at a specified price within a specified period of time or on a specified date from or to the writer of the option. The writer of options receives premiums and bears the risk of unfavorable changes in the market price of the financial instruments underlying the options. Swaps are contractual agreements in which two counterparties agree to exchange certain cash flows, at specified future dates, based on an agreed contract. Certain agreements may result in combined interest rate and foreign exchange exposures. Entering into swap agreements may involve the risk of credit losses in the event of counterparty default. To the extent these derivatives are economically hedging financial instruments or securities positions of Nomura, the overall risk of loss may be fully or partly mitigated by the hedged position. Nomura seeks to minimize its exposure to market risk arising from its use of these derivatives through various control policies and procedures, including position limits, monitoring procedures and hedging strategies whereby Nomura enters into offsetting or other positions in a variety of financial instruments. Derivatives used for non-trading Nomura’s principal objectives in using derivatives for non-trading non-trading Fair value hedges Nomura designates certain derivatives as fair value hedges of interest rate risk arising from specific financial liabilities and foreign currency risk arising from specific foreign currency denominated debt securities. These derivatives are effective in reducing the risk associated with the exposure being hedged and are highly correlated with changes in the fair value and foreign currency rates of the underlying hedged items, both at inception and throughout the life of the hedging relationship. Changes in fair value of the hedging derivatives are reported together with those of the hedged liabilities and assets through the consolidated statements of income within Interest expense Revenue — Other Net investment hedges Nomura designates certain derivatives designated as hedges of its net investment in foreign operations relating to specific subsidiaries which have non-Japanese Revenue-Other Accumulated other comprehensive income (loss) Concentrations of credit risk for derivatives The following tables present Nomura’s significant concentration of exposures to credit risk in OTC derivatives with financial institutions including transactions cleared through central counterparties as of March 31, 2022 and 2023. The gross fair value of derivative assets represents the maximum amount of loss due to credit risk that Nomura would incur if the counterparties of Nomura failed to perform in accordance with the terms of the instruments and any collateral or other security Nomura held in relation to those instruments proved to be of no value.

Offsetting of derivatives Counterparty credit risk associated with derivatives is controlled by Nomura through credit approvals, limits and monitoring procedures. To reduce the risk of loss, Nomura requires collateral, principally cash collateral and government securities, for certain derivative transactions. In certain cases, Nomura may agree for such collateral to be posted to a third-party custodian under a control agreement that enables Nomura to take control of such collateral in the event of counterparty default. From an economic standpoint, Nomura evaluates default risk exposure net of related collateral. Furthermore, OTC derivative transactions are typically documented under industry standard master netting agreements which mitigate Nomura’s credit exposure to counterparties. A master netting agreement is a single agreement with a counterparty that permits multiple transactions governed by that agreement to be terminated or accelerated and settled through a single payment in a single currency in the event of a default of the counterparty (“close-out For certain OTC centrally-cleared and exchange-traded derivatives, the clearing or membership agreements entered into by Nomura provide similar rights to Nomura in the event of default of the relevant central clearing party or exchange. Nomura generally seeks to obtain an external legal opinion in order to ascertain the enforceability of such close-out For certain counterparties and/ or in certain jurisdictions, Nomura may enter into derivative transactions which are not documented under a master netting agreement. Even when derivatives are documented under such agreements, Nomura may not have obtained, or may not be able to obtain evidence to determine with sufficient certainty that close-out close-out Nomura considers the enforceability of a master netting agreement in determining how credit risk arising from transactions with a specific counterparty is hedged, how counterparty credit exposures are calculated and applied to credit limits and the extent and nature of collateral requirements from the counterparty.

Fair value hedges Nomura issues Japanese Yen and foreign currency denominated debt with both fixed and floating interest rates. Nomura generally enters into swap agreements to convert fixed rate interest payments on its debt obligations to a floating rate and applies fair value hedge accounting to these instruments.

These features would require Nomura to post additional collateral or settle the instrument upon occurrence of a credit event, the most common of which would be a downgrade in the Company’s long-term credit rating. The aggregate fair value of all derivatives with credit-risk-related contingent features that are in a liability position as of March 31, 2022 was ¥638 billion with related collateral pledged of ¥421 billion. In the event of a one-notch The aggregate fair value of all derivatives with credit-risk-related contingent features that are in a liability position as of March 31, 2023 was ¥574 billion with related collateral pledged of ¥403 billion. In the event of a one-notch Credit derivatives Credit derivatives are derivatives in which one or more of their underlying reference assets of the instrument are related to the credit risk of a specified entity (or group of entities) or an index based on the credit risk of a group of entities that expose the seller of credit protection to potential loss from credit events specified in the contract. Written credit derivatives are instruments or embedded features where Nomura assumes third party credit risk, either as guarantor in a guarantee-type contract, or as the party that provides credit protection in an option-type contract, credit default swap, or any other credit derivative contract. Nomura enters into credit derivatives as part of its normal trading activities as both purchaser and/ or seller of protection for credit risk mitigation, proprietary trading positions and for client transactions. The most common type of credit derivatives used by Nomura are single-name credit default swaps where settlement of the derivative is based on the credit risk of a single reference entity or obligation. Nomura also writes credit derivatives linked to the performance of credit default indices and issues other credit risk related portfolio products. Nomura would have to perform under a credit derivative contract if a credit event as defined in the respective contract occurs. Typical credit events include bankruptcy, failure to pay and restructuring of obligations of the underlying reference asset. Credit derivatives written by Nomura are either cash or physically settled. In cash-settled instruments, once payment is made upon an event of default, the contract usually terminates with no further payments due. Nomura generally has no right to assume the reference assets of the counterparty in exchange for payment, nor does Nomura usually have any direct recourse to the actual issuers of the reference assets to recover the amount paid. In physically settled contracts, upon a default event, Nomura takes delivery of the reference asset in return for payment of the full notional amount of the contract. Nomura actively monitors and manages its credit derivative exposures. Where protection is sold, risks may be mitigated by purchasing credit protection from third parties either on identical underlying reference assets or on underlying reference assets with the same issuer which would be expected to behave in a correlated fashion. The most common form of recourse provision to enable Nomura to recover from third parties any amounts paid under a written credit derivative is therefore not through the derivative itself but rather through the purchase of separate credit derivative protection with identical or correlated underlying reference assets. The extent of these purchased credit protection contracts is quantified in the following tables under the column titled “Purchased Credit Protection.” These amounts represent purchased credit protection with identical underlying reference assets to the written credit derivatives which act as a hedge against Nomura’s exposures. To the extent Nomura is required to pay out under the written credit derivative, a similar amount would generally become due to Nomura under the purchased credit protection. Written credit derivatives have a stated notional amount which represents the maximum payment Nomura may be required to make under the written credit derivative. However, this is generally not a true representation of the amount Nomura will actually pay under these contracts as there are other factors that affect the likelihood and amount of any payment obligations under the contracts, including: Probability of default Recovery value on the underlying asset The following tables present information about Nomura’s written credit derivatives and purchased credit protection with identical underlying reference assets as of March 31, 2022 and 2023.

The following tables present information about Nomura’s written credit derivatives by external credit rating of the underlying asset. Credit ratings are based on S&P Global Ratings (“S&P”), or if not rated by S&P, based on Moody’s Investors Service. If credit ratings from either of these agencies are not available, the credit ratings are based on Fitch Ratings Ltd. or Japan Credit Rating Agency, Ltd. For credit default indices, the credit rating is determined by taking the weighted average of the external credit ratings given for each of the underlying reference entities comprising the portfolio or index.

Derivatives entered into in contemplation of sales of financial assets Nomura enters into transactions which involve both the transfer of financial assets to a counterparty and a separate agreement entered contemporaneously with the same counterparty through which Nomura retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. These transactions primarily include sales of securities with bilateral OTC total return swaps or other derivative agreements which are in-substance These transactions are accounted for as sales of the securities with the derivative accounted for separately if the criteria for derecognition of the securities under ASC 860 are met. Where the derecognition criteria are not met, the transfer and separate derivative are accounted for as a single collateralized financing transaction which is reported within Long-term borrowing Nomura entered into certain contemporaneous transactions involving the transfer of securities that are accounted for as sales, where substantially all of the economic exposures to the transferred securities are retained through total return swaps but does not retain control over the assets transferred.

Asset management services • Management of funds, investment trusts and other investment vehicles • Provision of investment advisory services • Provision of custodial and administrative services to customers • Management fees earned by Nomura in connection with managing a fund, investment trust or other vehicle generally are recognized on a straight-line basis based on time elapsed. • Performance-based fees are variable consideration recognized when the performance metric has been determined since only at such point is it probable that a significant reversal of revenue will not occur. • Custodial and administrative fees are recognized on a straight-line basis over time based on time elapsed. Where revenue is recognized at a point in time, payments of fees are typically received at the same time as when the performance obligation is satisfied, or within several days or months after satisfying a performance obligation. In relation to revenue recognized over time, payments of fees are typically settled monthly, quarterly or semi-annually. The underlying contracts entered into by Nomura in connection with the services described above typically do not have significant financing components. If such components exist in a contract, Nomura has made an accounting policy permitted by ASC 606 “ Revenue from Contracts with Customers Customer contract balances When Nomura or the customer performs in accordance with the terms of a customer contract, a contract asset, customer contract receivable or contract liability is recognized in Nomura’s consolidated balance sheet. A contract asset represents accrued revenue recognized by Nomura for completion or partially completion of a performance obligation, namely a right of Nomura to receive consideration for providing the service to the customer, which is conditional on factors or events other than the passage of time. A customer contract receivable is an unconditional right of Nomura to receive consideration in exchange for services provided. Both contract assets and customer contract receivables are reported in Receivables from Customers Payables to Customers The following table presents the balances of customer contract receivables and contract liabilities in scope of ASC 606. The amount of contract assets as of March 31, 2022 and 2023 was not significant.

The balance of contract liabilities as of March 31, 2021 and 2022 were recognized as revenue for the year ended March 31, 2022 and 2023, respectively. Nomura recognized ¥8,108 million of revenue from performance obligations satisfied in previous periods for the year ended March 31, 2022. The balance of contract liabilities as of March 31, 2022 were recognized as revenue for the year ended March 31, 2023. Nomura recognized ¥4,876 million of revenue from performance obligations satisfied in previous periods for the year ended March 31, 2023. Transaction price allocated to the remaining performance obligations In the ordinary course of business, Nomura may enter into customer contracts where the performance obligations are wholly or partially unsatisfied as of fiscal year ends. The total transaction prices allocated to the remaining unsatisfied performance obligations within these customer contracts were ¥1,350 million as of March 31, 2022 and ¥1,189 million as of March 31, 2023. As permitted by ASC 606, Nomura has elected not to disclose information about remaining performance obligations that have an individual estimated contract period of one year or less.

Collateralized transactions | 5. Collateralized transactions: Nomura enters into collateralized transactions, including reverse repurchase agreements, repurchase agreements, securities borrowing transactions, securities lending transactions, other secured borrowings and similar transactions mainly to meet clients’ financing needs, finance trading inventory positions and obtain securities for settlement. Reverse repurchase agreements, repurchase agreements, securities borrowing transactions and securities lending transactions are typically documented under industry standard master netting agreements which mitigate Nomura’s credit exposure to counterparties. For certain centrally-cleared reverse repurchase and repurchase agreements, the clearing or membership agreements entered into by Nomura provide similar rights to Nomura in the event of default of the relevant central clearing counterparty. Nomura generally seeks to obtain an external legal opinion in order to ascertain the enforceability of such close-out Nomura may enter into reverse repurchase agreements, repurchase agreements, securities borrowing and securities lending transactions with certain types of counterparty and in certain jurisdictions which are not documented under a master netting agreement. Even when these transactions are documented under such master netting agreements, Nomura may not have obtained, or may not be able to obtain, evidence to determine with sufficient certainty that the close-out close-out Nomura considers the enforceability of a master netting agreement in determining how credit risk arising from transactions with a specific counterparty is hedged, how counterparty credit exposures are calculated and applied to credit limits and the extent and nature of collateral requirements from the counterparty. In all of these transactions, Nomura either receives or provides collateral, including Japanese and non-Japanese Offsetting of certain collateralized transactions Reverse repurchase agreements and repurchase agreements, securities borrowing and lending transactions with the same counterparty documented under a master netting agreement are offset in the consolidated balance sheets where specific criteria as defined by ASC 210-20 close-out The following tables present information about offsetting of these transactions in the consolidated balance sheets as of March 31, 2022 and 2023, together with the extent to which master netting agreements entered into with counterparties and central clearing parties permit additional offsetting in the event of counterparty default.

Securitizations and Variable Interest Entities [Abstract] | |
Securitizations and Variable Interest Entities | 6. Securitizations and Variable Interest Entities: Securitizations Nomura utilizes special purpose entities (“SPEs”) to securitize commercial and residential mortgage loans, government agency and corporate securities and other types of financial assets. Those SPEs are incorporated as stock companies, Tokumei kumiai (silent partnerships), Cayman special purpose companies (“SPCs”) or trust accounts. Nomura’s involvements with these SPEs includes structuring SPEs, underwriting, distributing and selling debt instruments and beneficial interests issued by SPEs to investors. Nomura accounts for the transfer of financial assets in accordance with ASC 860. This statement requires that Nomura accounts for the transfer of financial assets as a sale when Nomura relinquishes control over the assets. ASC 860 deems control to be relinquished when the following conditions are met: (a) the assets have been isolated from the transferor (even in bankruptcy or other receivership), (b) the transferee has the right to pledge or exchange the assets received, or if the transferee is an entity whose sole purpose is to engage in securitization or asset-backed financing activities, the holders of its beneficial interests have the right to pledge or exchange the beneficial interests, and (c) the transferor has not maintained effective control over the transferred assets. Where Nomura retains an interest in the financial assets, including residual interests in the SPEs, any such interests are measured at fair value and reported within Trading assets Revenue-Net As noted above, Nomura may have continuing involvement with SPEs to which Nomura transferred assets. For the years ended March 31, 2022 and 2023, Nomura received cash proceeds from SPEs in new securitizations of ¥464 billion and ¥285 billion, respectively, and the associated gain on sale was ¥9 billion and ¥1 billion, respectively. For the years ended March 31, 2022 and 2023, Nomura received debt securities issued by these SPEs with an initial fair value of ¥1,890 billion and ¥458 billion, respectively, and cash inflows from third parties primarily on the sale of those debt securities of ¥1,759 billion and ¥436 billion, respectively. The cumulative balance of financial assets transferred to SPEs with which Nomura has continuing involvement was ¥5,829 billion and ¥5,745 billion as of March 31, 2022 and 2023, respectively. Those transferred financial assets are substantially government, agency and municipal securities. Nomura’s retained interests were ¥131 billion and ¥168 billion as of March 31, 2022 and 2023, respectively. For the years ended March 31, 2022 and 2023, Nomura received cash flows of ¥39 billion and ¥26 billion, respectively, from the SPEs on such retained interests held in the SPEs. Nomura does not provide any financial support to SPEs beyond its contractual obligations as of March 31, 2022 and 2023. The following tables present the fair value of retained interests which Nomura has continuing involvement in SPEs and their classification in the fair value hierarchy, categorized by the type of transferred assets as of March 31, 2022 and 2023.

Nomura retains, purchases and sells variable interests in VIEs in connection with its market-making, investing and structuring activities. If Nomura has power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, and through Nomura’s interest in the VIE, Nomura has the right to receive benefits or the obligation to absorb losses that could be potentially significant to the VIE, Nomura is the primary beneficiary of the VIE and must consolidate the entity, provided that Nomura does not act as a fiduciary for other interest holders. Nomura’s consolidated VIEs include those that were created to market structured securities to investors by repackaging corporate convertible securities, mortgages and mortgage-backed securities. Certain VIEs used in connection with Nomura’s aircraft leasing business as well as other purposes are consolidated. Nomura also consolidates certain investment funds for which Nomura is the primary beneficiary. The power to direct the most significant activities may take a number of different forms in different types of VIEs. For transactions such as securitizations, investment funds, and CDOs, Nomura generally considers collateral management and servicing to represent the power to make the most significant decisions, unless such roles are deemed to be a fiduciary relationship. Accordingly, Nomura does not consolidate such types of VIEs for which it does not act as collateral manager or servicer unless Nomura has the unilateral right to replace the collateral manager or servicer or to require liquidation of the entity. For many transactions, such as where VIEs are used for re-securitizations re-securitization in many cases has determined that it is not the primary beneficiary on the basis that power to direct the most significant activities relating to these entities are shared with third party investors. Nomura has consolidated certain VIEs where it was determined that third party investors were not involved in the design of the VIEs, including where the size of third party investment was insignificant at inception of the transaction. The following table presents the classification of consolidated VIEs’ assets and liabilities in these consolidated financial statements as of March 31, 2022 and 2023. Most of these assets and liabilities are related to consolidated VIEs which securitize corporate convertible securities, mortgages and mortgage-backed securities. The assets of a consolidated VIE may only be used to settle obligations of that VIE. Creditors do not typically have any recourse to Nomura.

Nomura also holds variable interests in VIEs where Nomura is not the primary beneficiary. Nomura’s variable interests in such VIEs include senior and subordinated debt, residual interests, and equity interests associated with commercial and residential mortgage-backed and other asset-backed securitizations and structured financings, equity interests in VIEs which were formed primarily to acquire high yield leveraged loans and other lower investment grade debt obligations, residual interests in operating leases for aircraft held by VIEs, and loans and investments in VIEs that acquire operating businesses. The following tables present the carrying amount of variable interests of unconsolidated VIEs and maximum exposure to loss associated with these variable interests as of March 31, 2022 and 2023. Maximum exposure to loss does not reflect Nomura’s estimate of the actual losses that could result from adverse changes, nor does it reflect the economic hedges Nomura enters into to reduce its exposure. The risks associated with VIEs in which Nomura is involved are limited to the amount recorded in the consolidated balance sheets and the amount of any undrawn commitments and financial guarantees issued.

Financing Receivables [Abstract] | |
Financing receivables | 7. Financing receivables: In the normal course of business, Nomura extends financing to clients primarily in the form of loan receivables, loan commitments and collateralized agreements such as reverse repurchase agreements and securities borrowing transactions. These financing receivables are recognized as assets on Nomura’s consolidated balance sheets at fair value or on amortized cost basis and provide a contractual right to receive money either on demand or on future fixed or determinable dates. The carrying value of financing receivables measured on an amortized cost basis is adjusted for allowances for current expected credit losses defined by ASC326 “ Financial Instruments — Credit Losses Allowance for credit losses Collateralized agreements Collateralized agreements consist of reverse repurchase agreements reported as Securities purchased under agreements to resell and securities borrowing transactions reported as Securities borrowed non-cash See Note 5 “ Collateralized transactions Loans receivable The key types of loans receivable recognized by Nomura are loans at banks, short-term secured margin loans, inter-bank money market loans and corporate loans. Loans at banks include both retail and commercial secured loans and traditional unsecured loans mainly extended by Nomura Trust & Banking Co., Ltd. Where retail and commercial loans are secured by real estate or securities, Nomura is exposed to the risk of a decline in the value of the underlying collateral. Loans at banks also include unsecured commercial loans provided to investment banking clients for relationship purposes. For unsecured commercial loans, Nomura is exposed to risk of default of the counterparty, although these counterparties usually have high or good credit ratings. Where loans are secured by guarantees, Nomura is also exposed to the risk of default by the guarantor. Short-term secured margin loans are margin loans provided to clients in connection with securities brokerage business in retail and wealth management services. These loans provide funding for clients in order to purchase securities. Nomura requests initial margin in the form of acceptable securities or deposits against these loans and holds the purchased securities as collateral through the life of the loans. If the value of the securities declines by more than specified amounts, Nomura can make additional frequent margin calls in order to maintain a specified loan-to-value Inter-bank money market loans are loans to financial institutions in the inter-bank money market, where overnight and intra-day loans is limited as only qualified financial institutions can participate in these markets and these loans are usually overnight or short-term in nature. Allowances for current expected credit losses against inter-bank money market loans are therefore usually not significant. Corporate loans are primarily commercial loans provided to corporate clients excluding those classified as Loans at banks. Corporate loans include loans secured by real estate or securities, unsecured commercial loans provided to investment banking clients for relationship purposes. The risk to Nomura of making these loans is similar to those risks arising from commercial loans reported in loans at banks.

There were no significant purchases or sales of loans receivable during the years ended March 31, 2022 and 2023 , respectively , respectively. Net unamortized deferred fees and costs related to loans receivable carried at amortized cost were not significant Allowances for current expected credit losses Management has established allowances for current expected credit losses using the current expected credit losses impairment model (“CECL impairment model”) against the following types of financial instruments, including financing receivables, which are not measured at fair value on a recurring basis, to reflect the net amount Nomura expects to collect: • Loans receivable and written unfunded loan commitments; • Cash deposits; • Collateralized agreements such as reverse repos and securities borrowing transactions; • Customer contract assets and receivables; and • Other receivables including margin receivables, security deposits, default fund contributions to central clearing counterparties and net investments in finance leases. C The risk of loss is considered, even when that risk of loss is remote. While management has based its estimate of the allowances for current expected credit losses on the best information available, future adjustments to the allowances may be necessary as a result of changes in the economic environment or variances between actual results and original assumptions. Nomura has elected to exclude accrued interest receivable from the amortized cost basis of financial instruments used to measure expected credit losses. The amount of accrued interest receivable as of March 31, 2022 and March 31, 2023 was not significant. The methodology used by Nomura to determine allowances for current expected credit losses in accordance with the CECL impairment model primarily depends on the nature of the financial instrument and whether certain practical expedients permitted by ASC 326 are applied by Nomura. Financial instruments subject to the CECL impairment model are charged off when Nomura has deemed the loan or receivable as uncollectible, namely management believes there is no reasonable expectation of collecting future contractual cash flows and all commercially reasonable means of recovering outstanding principal and interest balances have been exhausted. The following table summarizes the methodology used for each significant type of financial instrument subject to the CECL impairment model and the key assumptions used which have impacted the measurement of current expected credit losses during the year ended March 31, 2023. Financial instrument Methodology to determine current expected credit losses Loans, written loan commitments and certain deposits • Full loss rate model developed by Nomura’s Risk department • Measures expected credit losses based on probability of default (PD), Loss Given Default (LGD) and Exposure at Default (EAD) inputs. • PD inputs incorporate forward-looking scenarios used by Nomura for internal risk management and capital purposes. Financial instrument Methodology to determine current expected credit losses • Immediate reversion method used for periods beyond which reasonable and supportable forecast is not available. • For financial instruments which have defaulted or are probable of defaulting, expected credit losses measured using discounted cash flow analyses or, where the financial instrument is collateral dependent, based on any shortfall of fair value of the underlying collateral. Collateralized agreements, short-term secured margin loans and cash prime brokerage loans • For reverse repos and short-term secured margin loans and cash prime brokerage loans where frequent margining is required and the counterparty has ability to replenish margin, as permitted by a practical expedient provided by ASC 326 expected credit losses are limited to difference between carrying value of the reverse repo or margin loan and fair value of underlying collateral. • Securities borrowing transactions typically have very short expected lives and are collateralized and therefore expected credit losses are generally determined qualitatively to be insignificant based on historical experience and consistent monitoring of collateral. Customer contract assets and receivables • Expected credit losses typically based on aging analysis where loss rates are applied to the carrying value based on historical experience, the current economic climate and specific information about the ability of the client to pay. The following table presents changes in the allowances for current expected credit losses for the year ended March 31, 2021 as determined using the CECL impairment model defined by ASC 326.

Troubled debt restructurings In the ordinary course of business, Nomura may choose to restructure a loan classified as held for investment either because of financial difficulties of the borrower, or simply as a result of market conditions or relationship reasons. A troubled debt restructuring (“TDR”) occurs when Nomura (as lender) for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that Nomura would not otherwise consider. Expected credit losses for a loan being restructured under a TDR which only involve modification of the loan’s terms (rather than receipt of assets in full or partial settlement) is typically determined using a discounted cash flow analysis. Assets received in full or partial satisfaction of a loan in a TDR are recognized at fair value. Discussions continue with various borrowers to modify the existing contractual terms of certain loans. These modifications where the borrower is deemed to be in financial difficulty and Nomura has, or expects to, grant a financial concession would typically be accounted for and reported as a TDR. The amounts of TDRs which occurred during the years ended March 31, 2022 and 2023 were not significant. Nonaccrual and past due loans Loans are placed on a nonaccrual status if interest is deemed uncollectible. Nomura policy is to define interest as being uncollectible if the borrower is determined to be in financial difficulty or an interest or principal payment on the loans is 90 days or more past due. Where a loan is placed on a nonaccrual status, any accrued but unpaid interest receivable reversed and no further accrual of interest is permitted. Interest income is subsequent recognized when a cash payment is received from the borrower using the cash basis method. Generally loans are only returned to an accrual status if the loan is brought contractually current, i.e., all overdue principal and interest amounts are paid. In limited circumstances, a loan which has not been brought contractually current will also be returned to an accrual status if all principal and interest amounts contractually due are reasonably assured of repayment within a reasonable period of time or there has been a sustained period of repayment performance by the borrower. As of March 31, 2022, there were ¥62,289 million of loans which were placed on a nonaccrual status, primarily secured corporate loans. Corporate loans on a non-accrual As of March 31, 2023, there were ¥ 16,417 million of loans which were placed on a nonaccrual status, primarily secured corporate loans. Corporate loans on a non-accrual status as of March 31, 2023 include ¥ 14,233 million of loans which didn’t recognize allowances for current expected credit losses due to fair value of the collateral excess value of the loan. The amount of loans which were 90 days past due but were not on a nonaccrual status was not significant. Credit quality indicators Nomura is exposed to credit risks due to a decline in the value of loans or a default caused by deterioration of creditworthiness or bankruptcy of the borrower. Nomura’s risk management framework for such credit risks is based on a risk assessment through an internal rating process, in depth pre-financing The following tables present an analysis of each class of loans not carried at fair value using Nomura’s internal ratings or equivalent credit quality indicators applied by subsidiaries by years of origination as of March 31, 2022 and 2023.

The following table presents a definition of each of the internal ratings used in the Nomura Group. Rating Range Definition AAA Highest credit quality. An obligor or facility has extremely strong capacity to meet its financial commitments. ‘AAA range’ is the highest credit rating assigned by Nomura. Extremely low probability of default. AA Very high credit quality category. An obligor or facility has very strong capacity to meet its financial commitments. Very low probability of default but above that of ‘AAA range.’ A High credit quality category. An obligor or facility has strong capacity to meet its financial commitments but is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than those in higher-rated categories. Low probability of default but higher than that of ‘AA range.’ BBB Good credit quality category. An obligor or facility has adequate capacity to meet its financial commitments. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to meet its financial commitments. Medium probability of default but higher than that of ‘A range.’ BB Speculative credit quality category. An obligor or facility is less vulnerable in the near term than other lower-ratings. However, it faces major ongoing uncertainties and exposure to adverse business, financial, or economic conditions which could lead to the inadequate capacity to meet its financial commitments. Medium to high probability of default but higher than that of ‘BBB range.’ B Highly speculative credit quality category. An obligor or facility is more vulnerable than those rated ‘BB range’, but the obligor currently has the capacity to meet its financial commitments. Adverse business, financial, or economic conditions will likely impair the issuer’s or obligor’s capacity or willingness to meet its financial commitments. High probability of default—more than that of ‘BB range.’ CCC Substantial credit risk. An obligor or facility is currently vulnerable, and is dependent upon favorable business, financial, and economic conditions to meet its financial commitments. Strong probability of default – more than that of ‘B range.’ CC Default category. An obligor or facility is currently highly vulnerable to nonpayment. C Default category. An obligor or facility is currently extremely vulnerable to nonpayment. D Failure of an obligor to make payments in full and on time of any financial obligations, markedly disadvantageous modification to a contractual term compared with the existing obligation, bankruptcy filings, administration, receivership, liquidation or other winding-up or cessation of business of an obligor or other similar situations. Nomura reviews internal ratings at least once a year by using available credit information of obligors including financial statements and other information. Internal ratings are also reviewed more frequently for high-risk obligors or problematic exposures and any significant credit event of obligors will trigger an immediate credit review process. |

Impairment testing of goodwill is inherently subjective and often requires management judgment to determine when to perform an impairment test, whether qualitatively the fair value of a reporting unit exceeds its carrying value and also to estimate the fair value of a reporting unit when a quantitative impairment test is required. An annual goodwill impairment test was performed in the quarter ended March 31, 2022 and 2023. The estimated fair value of the reporting unit is expected to exceed carrying value and therefore no impairment loss was recognized.

Earnings Per Share [Abstract] | |
Earnings per share | 11. Earnings per share: Basic and diluted earnings per share (“EPS”) are presented on the face of the consolidated statements of income. Basic EPS is calculated by dividing net income attributable to NHI shareholders by the weighted average number of the Company’s common shares outstanding during the year. The calculation of diluted EPS is similar to basic EPS, except that the weighted average number of the Company’s common shares is adjusted to reflect all dilutive instruments where the Company’s common shares are potentially deliverable during the year. In addition, net income attributable to NHI shareholders is adjusted for any change in income or loss that would result from the assumed conversion of dilutive instruments issued by subsidiaries and affiliates. The following table presents a reconciliation of the amounts and the numbers used in the calculation of net income attributable to NHI shareholders per share (basic and diluted) for the years ended March 31, 2021, 2022 and 2023. Millions of yen except per share data presented in yen Year ended March 31 2021 2022 2023 Basic— Net income attributable to NHI shareholders ¥ 153,116 ¥ 142,996 ¥ 92,786 Weighted average number of shares outstanding 3,055,525,640 3,063,524,091 3,006,744,201 Net income attributable to NHI shareholders per share ¥ 50.11 ¥ 46.68 ¥ 30.86 Diluted— Net income attributable to NHI shareholders ¥ 153,064 ¥ 142,861 ¥ 92,606 Weighted average number of shares outstanding 3,147,338,609 3,158,708,013 3,114,313,612 Net income attributable to NHI shareholders per share ¥ 48.63 ¥ 45.23 ¥ 29.74 Net income attributable to NHI shareholders was adjusted to reflect the decline in Nomura’s equity share of earnings of subsidiaries and affiliates for the years ended March 31, 2021, 2022 and 2023 arising from options to purchase common shares issued by subsidiaries and affiliates. The weighted average number of shares used in the calculation of diluted EPS reflects the increase in potential issuance of the Company’s common shares arising from stock-based compensation plans by the Company and affiliates, which would have minimal impact on EPS for the years ended March 31, 2021, 2022 and 2023. Antidilutive stock options and other stock-based compensation plans to purchase 12,398,500, 9,716,800 and 7,147,000 of the Company’s common shares were not included in the computation of diluted EPS for the years ended March 31, 2021, 2022 and 2023, respectively. Subsequent Events On April 26, 2023, the Company adopted a resolution to set up a share buyback program. See Note 1 6 Shareholders’ equity On May 15, 2023, the Company adopted a resolution to grant Restricted Stock Units (“RSUs”). See Note 1 3 Deferred compensation awards |

Employee Benefit Plans [Abstract] | |
Employee benefit plans | 1 2 Nomura provides various pension plans and other post-retirement benefits which cover certain eligible employees worldwide. In addition, Nomura provides health care benefits to certain active and retired employees through its Nomura Securities Health Insurance Society (“NSHIS”). Defined benefit pension plans— The Company and certain subsidiaries in Japan (“Japanese entities”) have contributory funded benefit pension plans for eligible employees. The benefits are paid as annuity payments subsequent to retirement or as lump-sum payments at the time of retirement based on a combination of years of service, age at retirement and employee’s choice. The benefits under the plans are calculated based upon position, years of service and reason for retirement. In addition to the plans described above, certain Japanese entities also have unfunded lump-sum payment plans. Under these plans, employees with at least two years of service are generally entitled to lump-sum payments upon termination of employment. The benefits under the plans are calculated based upon position, years of service and the reason for retirement. Nomura’s funding policy is to contribute annually the amount necessary to satisfy local funding standards. In December 2008, certain contributory funded benefit pension plans and unfunded lump-sum payment plans were amended and “Cash balance pension plans” were introduced. Participants receive an annual benefit in their cash balance pension plan accounts, which is computed based on compensation of the participants, adjusted for the changes in market interest rate. In April 2020, certain Japanese entities amended their pension plans. Certain defined benefit pension plans and unfunded lump-sum payment plans were either closed for additional funding or abolished. Defined contribution pension plans and cash balance pension plans have replaced them for future contributions. Certain overseas subsidiaries have various local defined benefit plans covering certain employees. Nomura recognized an asset for surplus pension benefits for these plans amounting to ¥7,911 million and ¥5,795 million as of March 31, 2022 and 2023, respectively. Net periodic benefit cost The following table presents the components of net periodic benefit cost for defined benefit plans of Japanese entities for the years ended March 31, 2021, 2022 and 2023. Nomura’s measurement date is March 31 for defined benefit plans of Japanese entities. Millions of yen Year ended March 31 2021 2022 2023 Service cost ¥ 6,721 ¥ 6,452 ¥ 6,398 Interest cost 1,786 2,042 2,432 Expected return on plan assets (5,826 ) (6,055 ) (5,968 ) Amortization of net actuarial losses 5,519 3,955 3,818 Amortization of prior service cost (1,521 ) (1,599 ) (1,607 ) Net periodic benefit cost ¥ 6,679 ¥ 4,795 ¥ 5,073 Prior service cost is amortized on a straight-line basis over the average remaining service period of active participants. Gains and losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets are amortized over the average remaining service period of active participants, which is 14 years. Benefit obligations and funded status The following table presents a reconciliation of changes in projected benefit obligation (“PBO”) and the fair value of plan assets, as well as a summary of the funded status of Japanese entities’ plans as of, and for the years ended March 31, 2022 and 2023.

In April 2020, defined contribution pension plans and cash balance pension plans were adopted for future contributions following the amendments of pension benefit plans. Certain contributory defined benefit pension plans were closed for additional funding and will be managed within the accumulated funds. Unfunded lump-sum payment plans were abolished and transferred to cash balance plans with the calculated amount of lump-sum retirement payment as of the amendment date. The following table presents the PBO, ABO and fair value of plan assets for Japanese entities’ plans with ABO and PBO in excess of plan assets as of March 31, 2022 and 2023.

March 31 2022 2023 Discount rate 0.8 % 1.3 % Rate of increase in compensation levels 0.3 % 0.4 % Interest crediting rate 2.9 % 2.8 % The following table presents the weighted-average assumptions used to determine the net periodic benefit cost of Japanese entities’ plans as of March 31, 2021, 2022 and 2023. Year ended March 31 2021 2022 2023 Discount rate 0.6 % 0.7 % 0.8 % Rate of increase in compensation levels 0.3 % 0.3 % 0.3 % Expected long-term rate of return on plan assets 2.6 % 2.6 % 2.6 % Interest crediting rate 3.0 % 2.9 % 2.9 % Nomura generally determines the discount rates for its defined benefit plans by referencing indices for long-term, high-quality debt securities and ensuring that the discount rate does not exceed the yield reported for those indices after adjustment for the duration of the plans’ liabilities. Nomura uses the expected long-term rate of return on plan assets to compute the expected return on assets. Nomura’s approach in determining the long-term rate of return on plan assets is primarily based on historical financial market relationships that have existed over time with the presumption that this trend will generally remain constant in the future. Plan assets Plan assets are managed with an objective to generate sufficient long-term value in order to enable future pension payouts. While targeting a long-term rate of return on plan assets, Nomura aims to minimize short-term volatility by managing the portfolio through diversifying risk. Based on this portfolio policy, the plan assets are invested diversely. The plan assets of domestic plans target to invest 15% For details of the levels of inputs used to measure the fair value of plan assets, see Note 2 “ Fair value measurements. The following tables present information about the fair value of plan assets of Japanese entities’ plans as of March 31, 2022 and 2023 within the fair value hierarchy.

Cash Flows Following the amendments of pension benefit plans in Japanese entities, certain contributory funded benefit pension plans were closed for additional funding and will be managed within the accumulated funds. The following table presents the expected benefit payments of Japanese entities’ plans during the next five fiscal years and in aggregate for the five fiscal years thereafter.

Nomura contributed ¥6,478 million, ¥6,709 million and ¥6,675 million to defined contribution pension plans for Japanese entities’ plans for the years ended March 31, 2021, 2022 and 2023, respectively. The contributions to overseas defined contribution pension plans were ¥8,035 million, ¥9,215 million and ¥11,964 million for the years ended March 31, 2021, 2022 and 2023, respectively. Health care benefits— The Company and certain subsidiaries provide certain health care benefits to both active and retired employees through NSHIS. The Company and certain subsidiaries also sponsor certain health care benefits to retired employees (“Special Plan”) and who participate in the Special Plan on a pay-all basis, i.e., by requiring a retiree contribution based on the estimated per capita cost of coverage. The Special Plan is a multi-employer post-retirement plan because it is jointly administered by NSHIS and the Japanese government, and the funded status of it is not computed separately. Therefore, although the Company and certain subsidiaries contribute some portion of the cost of retiree health care benefits not covered through retiree contributions, the Company and certain subsidiaries do not reserve for future costs. The health care benefit costs, which are equivalent to the required contribution, were ¥9,463 million, ¥10,035 million and ¥9,586 million for the years ended March 31, 2021, 2022 and 2023, respectively. |

Deferred Compensation Awards [Abstract] | |
Deferred compensation awards | 1 3 Nomura issues deferred compensation awards to senior management and employees, which are linked to the price of the Company’s common stock, in order to retain and motivate key staff. These stock-based compensation awards comprise Restricted Stock Unit (“RSU”) awards, Plan A and Plan B Stock Acquisition Right (“SAR”) awards, Notional Stock Unit (“NSU”) awards, and Collared Notional Stock Unit (“CSU”) awards. SAR Plan A awards are awards of stock options while RSU awards, SAR Plan B awards, NSU awards and CSU awards are all analogous to awards of restricted common stock. Certain deferred compensation awards include “Full Career Retirement” (“FCR”) provisions which permit recipients of the awards to continue to vest in the awards upon voluntary termination of employment if certain criteria based on corporate title and length of service within Nomura are met. The requisite service period for these awards ends on the earlier of the contractual vesting date and the date that the recipients become eligible for or claim FCR. Unless indicated below, deferred compensation awards are generally reduced, forfeited or clawed back in the event of termination of employment, material restatements of financial statements, material conduct issues, material damage to Nomura’s business or reputation, material downturns in the performance of the Nomura group and/or a material failure of risk management. RSU awards For each RSU award, one common stock of the Company is delivered. The awards generally have a graded vesting period from one The grant date fair value per award is determined using the price of the Company’s common stock. The following table presents activity relating to RSU awards for the year ended March 31, 2023. Outstanding (number of Nomura shares) Weighted-average grant date fair value per share Weighted-average remaining life until expiry (years) Outstanding as of March 31, 2022 122,119,390 ¥ 466 1.0 Granted 100,057,000 442 Forfeited (13,325,712 ) 456 Delivered (50,090,803 ) 466 Outstanding as of March 31, 2023 158,759,875 ¥ 451 1.0 The weighted-average grant date fair value per award for the year ended March 31, 2021, ¥418 , The total fair value of RSU awards vested during the years ended March 31, 2021, 2022 and 2023 10,327 million, ¥28,076 million and ¥ , respectively. The total intrinsic value of units delivered during the years ended March 31, 2021 and 2022 was ¥10,360 million and ¥28,704 million, respectively. A were with a total of As of March 31, 2023, total unrecognized compensation cost relating to RSU awards was ¥11,786 million which is expected to be recognized over a weighted average period of 1.8 years. SAR Plan B awards In prior years, the Company issued SAR Plan B awards linked to the price of the Company’s common stock pursuant to several stock unit plans. These awards vest and are exercisable into the Company’s common stock, have an exercise price of ¥1 per share and graded vesting generally over three years with certain longer vesting or holding periods where required under local regulations. The grant date fair value of SAR Plan B awards is determined using the price of the Company’s common stock. The following table presents activity relating to SAR Plan B awards for the year ended March 31, 2023. No new SAR Plan B awards have been granted since April 1, 2018.

See Note 1 1 “Earnings per share” NSU and CSU awards NSU and CSU awards are cash-settled awards linked to the price of the Company’s common stock. NSU awards replicate the key features of SAR Plan B awards described above but are settled in cash rather than exercisable into the Company’s common stock. CSU awards are similar to NSU awards but exposure to movements in the price of the Company’s common stock is subject to a cap and floor. Both types of award have graded vesting periods generally over three years with certain longer vesting periods where required by local regulations. The fair value of NSU and CSU awards are determined using the price of the Company’s common stock. The following table presents activity related to NSU and CSU awards for the year ended March 31, 2023.

With effect from April 1, 2022, the Company and its wholly-owned domestic subsidiaries have applied the Group Tax Sharing system. The Group Tax Sharing system is only available for a national tax. The Company does not have any significant impact on its net deferred tax liabilities on adoption of the Group Tax Sharing system. The effective statutory tax rate applicable to Nomura in Japan was approximately 31% as of March 31, 2021, 2022 and 2023, respectively. Foreign subsidiaries are subject to income taxes of the countries in which they operate. The relationship between income tax expense and pretax accounting income (loss) is affected by a number of items, including various tax credits, certain revenues not subject to income taxes, certain expenses not deductible for income tax purposes, changes in deferred tax valuation allowance and different enacted tax rates applicable to foreign subsidiaries. The following table presents a reconciliation of the effective income tax rate reflected in the consolidated statements of income to Nomura’s effective statutory tax rate for the years ended March 31, 2021, 2022 and 2023.

It is not practicable to determine the amount of income taxes payable in the event all such foreign earnings are repatriated. The following table presents changes in total valuation allowances recognized against deferred tax assets for the years ended March 31, 2021, 2022 and 2023. Millions of yen Year ended March 31 2021 2022 2023 Balance at beginning of year ¥ 388,411 ¥ 428,014 ¥ 466,145 Net change during the year 39,603 (1) 38,131 (2) 48,923 (3) Balance at end of year ¥ 428,014 ¥ 466,145 ¥ 515,068 (1) Primarily includes an increase of ¥48,883 million of valuation allowances of certain foreign subsidiaries primar i primarily primarily (2) Primarily includes an increase of ¥51,706 million of valuation allowances of certain foreign subsidiaries primarily primarily (3) Primarily includes an increase of ¥53,851 million of valuation allowances of certain foreign subsidiaries primarily primarily As of March 31, 2023, total operating loss carryforwards were ¥2,134,580 million, which included ¥440,983 million relating to the Company and domestic subsidiaries, ¥663,578 million relating to foreign subsidiaries in U.K., ¥663,629 million relating to foreign subsidiaries in U.S., ¥332,488 million relating to foreign subsidiaries in Hong Kong, and ¥33,902 million relating to foreign subsidiaries in other tax jurisdictions. Of this total amount, ¥1,265,887 million can be carried forward indefinitely, ¥759,573 million expires by March 31, 2033 and ¥109,120 million expires in later fiscal years. These numbers are presented before offset with any uncertain tax position discussed later. In determining the amount of valuation allowances to be recognized as of March 31, 2023, Nomura considered all available positive and negative evidence around the likelihood that sufficient future taxable income will be generated to realize the deferred tax assets in the relevant tax jurisdiction of the Company, its domestic subsidiaries and foreign subsidiaries. In Japan and other tax jurisdictions where domestic and foreign subsidiaries have experienced cumulative operating losses in recent years, these losses provide the most verifiable negative evidence available and outweigh positive evidence. While Nomura has considered certain future tax planning strategies as a potential source of future taxable income, no such strategies have been relied upon as positive evidence resulting in a reduction of valuation allowances in any major tax jurisdiction in which Nomura operates as of March 31, 2021, 2022 and 2023. In addition, valuation allowances have not been reduced in any of these periods as a result of changing the weighting applied to positive or negative evidence in any of the major tax jurisdictions in which Nomura operates. The determination of whether deferred tax assets will be realized, and therefore whether a valuation allowance is required, is inherently subjective and often requires management judgment around the future profitability of Nomura entities, an interpretation of tax rules by courts and regulatory authorities and tax examinations by taxing authorities, and the appropriate weighting of positive and negative evidence around the likelihood that sufficient future taxable income will be generated to realize deferred tax assets in the relevant tax jurisdiction. Nomura’s unrecognized tax benefits were ¥4,367 million, ¥35,774 million and ¥34,763 million as of March 31, 2021, 2022 and 2023 respectively. Out of the balance as of March 31, 2023, ¥ 5,766 million, if recognized, would favorably impact the effective tax rate in the future periods. The remaining balance would not favorably impact the effective tax rate as it is expected to increase operating loss carryforwards and corresponding valuation allowance. The movement of the gross amounts in unrecognized tax benefits during the year ended March 31, 2023 was a decrease of ¥1,011 million of which ¥504 million is presented as a reversal of a reduction in deferred tax assets for utilization of net operating loss carryforward. Out of the balance as of March 31, 2022, ¥6,273 million, if recognized, would favorably impact the effective tax rate in the future periods. The remaining balance would not favorably impact the effective tax rate as it is expected to increase operating loss carryforwards and corresponding valuation allowance. The movement of the gross amounts in unrecognized tax benefits during the year ended March 31, 2022 was an increase of ¥31,406 million of which ¥29,501 million is presented as a reduction to deferred tax assets for utilization of net operating loss carryforward. There were no significant movements in the gross amounts of unrecognized tax benefits for the years ended March 31, 2021. There were also no significant movements of the amount of interest and penalties recognized due to unrecognized tax benefits during the years ended March 31, 2021, 2022 and 2023. Nomura is under regular examination by the Japanese National Tax Agency and other taxing authorities in the major tax jurisdictions in which Nomura operates. Nomura regularly assesses the likelihood of additional assessments in each tax jurisdiction and the impact on the consolidated financial statements. It is reasonably possible that there may be an increase or decrease in unrecognized tax benefits within 12 months of March 31, 2023 depending on the outcome of the examinations. Quantification of an estimated range cannot be made at this time due to the uncertainty of the potential outcomes. However, Nomura does not expect that any change in the gross balance of unrecognized tax benefits would have a material effect on its financial condition. Nomura operates in multiple tax jurisdictions, and faces audits from various taxing authorities regarding many issues including, but not limited to, transfer pricing, the deductibility of certain expenses, foreign tax credits and other matters. The table below presents information regarding the earliest year in which Nomura remains subject to examination in the major tax jurisdictions in which Nomura operates as of March 31, 2023. Jurisdiction Fiscal year ended March 31, Japan 2018 (1) United Kingdom 2016 ( 2 United States 2019 (1) The earliest year in which Nomura remains subject to examination for transfer pricing issues is the fiscal year ended March 31, 2017 (2) The earliest year in which Nomura remains subject to examination for transfer pricing issues is the fiscal year ended March 31, 2016. |

Commitments, Contingencies and Guarantees [Abstract] | |
Commitments, contingencies and guarantees | 19. Commitments, contingencies and guarantees: Commitments— Credit and investment commitments In connection with its banking and financing activities, Nomura provides commitments to extend credit which general l Nomura has commitments to invest in various partnerships and other entities and also has commitments to provide financing for investments related to these partnerships. The outstanding commitments under these agreements are included below as commitments to invest. The following table presents a summary of the key types of outstanding commitments provided by Nomura as of March 31, 2022 and 2023. Millions of yen March 31, 2022 March 31, 2023 Commitments to extend credit Liquidity facilities to central clearing counterparties ¥ 1,135,695 ¥ 1,623,897 Other commitments to extend credit 877,156 1,010,332 Total ¥ 2,012,851 ¥ 2,634,229 Commitments to invest ¥ 32,286 ¥ 21,994 Maturity profile of these com rch 31 Millions of yen Total contractual amount Years to maturity Less than 1 year 1 to 3 years 3 to 5 years More than 5 years Commitments to extend credit Liquidity facilities to central clearing counterparties ¥ 1,623,897 ¥ 1,623,897 ¥ — ¥ — ¥ — Other commitments to extend credit 1,010,332 199,120 289,991 338,978 182,243 Total ¥ 2,634,229 ¥ 1,823,017 ¥ 289,991 ¥ 338,978 ¥ 182,243 Commitments to invest ¥ 21,994 ¥ 195 ¥ 1,292 ¥ 5,003 ¥ 15,504 The contractual amounts of these commitments to extend credit represent the maximum amounts at risk assuming the contracts are fully drawn upon, should all the counterparties default, and the value of all collateral or credit mitigations becomes worthless. The total contractual amount of these commitments may not represent actual future cash outflows since the commitments may expire without being drawn upon. The credit risk associated with these commitments varies depending on the clients’ creditworthiness and the value and quality of collateral held. Nomura evaluates each client’s creditworthiness on a case-by-case counterparty. Other commitments Purchase obligations for goods or services that include payments for construction-related, advertising, and computer and telecommunications maintenance agreements amounted to ¥ million as of March 31, 2022 and ¥ million as of March 31, 2023. As of March 31, 2023, these purchase obligations had the following maturities: Millions of yen Total Years of payment Less than 1 year 1 to 2 years 2 to 3 years 3 to 4 years 4 to 5 years More than 5 years Purchase obligations ¥ 99,134 ¥ 21,501 ¥ 7,767 ¥ 3,119 ¥ 63,879 ¥ 927 ¥ 1,941 Above table includes the commitment to purchase parts of the redeveloped real estate in Tokyo Nihonbashi district from the redevelopment association. Nomura has commitments under resale and repurchase agreements including amounts in connection with collateralized agreements and collateralized financing. These commitments amounted to ¥1,565 billion for resale agreements and ¥2,673 billion for repurchase agreements as of March 31, 2022 and ¥1,143 billion for resale agreements and ¥2,146 billion for repurchase agreements as of March 31, 2023. Nomura has commitments to purchase notes held by our clients. These commitments amounted to ¥ 15 billion as of March 31, 2022 and ¥ 14 billion as of March 31, 2023. In Japan, there is a market in which participants lend and borrow debt and equity securities without collateral to and from financial institutions. Under these arrangements, Nomura had obligations to return debt and equity securities borrowed without collateral of ¥1,219 billion and ¥952 billion as of March 31, 2022 and 2023, respectively. As a member of various securities clearing houses and exchanges, Nomura may be required to assume a certain share of the financial obligations of another member who may default on its obligations to the clearing house or the exchange. These guarantees are generally required under the membership agreements. To mitigate these risks, exchanges and clearing houses often require members to post collateral. The potential for Nomura to make payments under such guarantees is deemed remote. Contingencies— Investigations, lawsuits and other legal proceedings In the normal course of business as a global financial services entity, Nomura is involved in investigations, lawsuits and other legal proceedings and, as a result, may suffer loss from any fines, penalties or damages awarded against Nomura, any settlements Nomura chooses to make to resolve a matter, and legal and other advisory costs incurred to support and formulate a defense. The ability to predict the outcome of these actions and proceedings is inherently difficult, particularly where claimants are seeking substantial or indeterminate damages, where investigations and legal proceedings are at an early stage, where the matters present novel legal theories or involve a large number of parties, or which take place in foreign jurisdictions with complex or unclear laws. The Company regularly evaluates each legal proceeding and claim on a case-by-case Contingencies ” (“ASC 450”), the Company recognizes a liability for this risk of loss arising on each individual matter when a loss is probable and the amount of such loss or range of loss can be reasonably estimated. The amount recognized as a liability is reviewed at least quarterly and is revised when further information becomes available. If these criteria are not met for an individual matter, such as if an estimated loss is only reasonably possible rather than probable, no liability is recognized. However, where a material loss is reasonably possible, the Company will disclose details of the legal proceeding or claim below. Under ASC 450 an event is defined as reasonably possible if the chance of the loss to the Company is more than remote but less than probable. As of March 31, 2021, 2022 and 2023, a total liability of ¥62,889 million, ¥ million has been recognized, respectively, and reported within the consolidated balance sheets within Other liabilities million, respectively, which has been reported within the consolidated statements of income within Non-interest — Other The most significant actions and proceedings against Nomura are summarized below. The Company believes that, based on current information available as of the date of these consolidated financial statements, the ultimate resolution of these actions and proceedings will not be material to the Company’s financial condition. However, an adverse outcome in certain of these matters could have a material adverse effect on the consolidated statements of income or cash flows in a particular quarter or annual period. For certain of the significant actions and proceedings, the Company is currently able to estimate the amount of reasonably possible loss, or range of reasonably possible losses, in excess of amounts recognized as a liability (if any) against such cases. These estimates are based on current information available as of the date of these consolidated financial statements and include, but are not limited to, the specific amount of damages or claims against Nomura in each case. As of June 28, 2023, for those cases where an estimate of the range of reasonably possible losses can be made, the Company estimates that the total aggregate reasonably possible maximum loss in excess of amounts recognized as a liability (if any) against these cases is approximately ¥ 51 billion. For certain other significant actions and proceedings, the Company is unable to provide an estimate of the reasonably possible loss or range of reasonably possible losses because, among other reasons, (i) the proceedings are at such an early stage there is not enough information available to assess whether the stated grounds for the claim are viable; (ii) damages have not been identified by the claimant; (iii) damages are unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant legal issues to be resolved that may be dispositive, such as the applicability of statutes of limitations; (vi) there are novel or unsettled legal theories underlying the claims and/or (vii) a judgment has been made against Nomura but detailed reasons for the basis for the judgment and how the amount of the judgment has been determined have not yet been received. Nomura will continue to cooperate with regulatory investigations and to vigorously defend its position in the ongoing actions and proceedings set out below, as appropriate. Claims for reimbursement of tax credits paid on dividends on Italian shares have been made by the tax authorities in Pescara, Italy alleging breaches of the U.K.-Italy Double Taxation Treaty of 1998 against IBJ Nomura Financial Products (UK) PLC (“IBJN”) a group company which has been in members’ voluntary liquidation since 2000. An Italian Supreme Court judgment in June 2019 confirmed that an amount of approximately EUR million (comprised of tax credit refunds plus accrued interest), plus further interest, was payable by IBJN to the Italian tax authorities. In October 2010 and June 2012, two actions were brought against NIP, seeking recovery of payments allegedly made to NIP by Fairfield Sentry Ltd. and Fairfield Sigma Ltd. (collectively, “Fairfield Funds”), which are now in liquidation and were feeder funds to Bernard L. Madoff Investment Securities LLC (in liquidation pursuant to the Securities Investor Protection Act in the U.S. since December 2008) (“BLMIS”). The first suit was brought by the liquidators of the Fairfield Funds. It was filed on October 5, 2010 in the Supreme Court of the State of New York, but was subsequently removed to the United States Bankruptcy Court for the Southern District of New York. The second suit was brought by the Trustee for the liquidation of BLMIS (“Madoff Trustee”). NIP was added as a defendant in June 2012 when the Madoff Trustee filed an amended complaint in the United States Bankruptcy Court for the Southern District of New York. Both actions seek to recover approximately $34 million plus interest. Certain of the Company’s subsidiaries in the U.S. securitized residential mortgage loans in the form of residential mortgage-backed securities (“RMBS”). These subsidiaries did not generally originate mortgage loans, but purchased mortgage loans from third-party loan originators (“originators”). In connection with such purchases, these subsidiaries received loan level representations from the originators. In connection with the securitizations, the relevant subsidiaries provided loan level representations and warranties of the type generally described below, which mirror the representations the subsidiaries received from the originators. The loan level representations made in connection with the securitization of mortgage loans were generally detailed representations applicable to each loan and addressed characteristics of the borrowers and properties. The representations included, but were not limited to, information concerning the borrower’s credit status, the loan-to-value With respect to certain of the RMBS issued from 2005 to 2007, the relevant subsidiaries received claims demanding the repurchase of certain loans from trustees of various securitization trusts, made at the instance of one or more investors, or from certificate insurers. The total original principal amount of loans for which repurchase claims were received by the relevant subsidiaries within six years of each securitization is million. The relevant subsidiaries summarily rejected any demand for repurchase received after the expiration of the statute of limitations applicable to breach of representation claims. For those claims received within six years, the relevant subsidiaries reviewed each claim received, and rejected those claims believed to be without merit or agreed to repurchase certain loans for those claims that the relevant subsidiaries determined to have merit. In several instances, following the rejection of repurchase demands, investors instituted actions through the trustee alleging breach of contract from 2011 to 2014. The breach of contract claims that were brought within the six-year statute of limitations for breach of contract actions have survived motions to dismiss and discovery was completed and Notes of Issue were filed. The Company has been engaged in efforts to resolve the actions outside of Court; certificateholder approval has been obtained for five settlement agreements and the Court is currently reviewing the agreements for approval. A monoline insurer, Ambac Assurance Corp (“Ambac”), brought an action in April 2013 against Nomura Credit & Capital, Inc. (“NCCI”) and Nomura Holding America Inc. (“NHA”) alleging breach of contract with respect to representations concerning specific loan characteristics and fraud in the inducement of the insurance contract based on misrepresentations concerning the loans for two trusts insured by Ambac. The court dismissed all claims against NHA. Ambac and NCCI resolved all claims and the action was dismissed pursuant to a stipulation filed January 3, 2023. In November 2011, NIP was served with a claim filed by the Madoff Trustee in the United States Bankruptcy Court for the Southern District of New York. This is a clawback action similar to claims filed by the Madoff Trustee against numerous other institutions. The Madoff Trustee alleges that NIP received redemptions from the BLMIS feeder fund, Harley International (Cayman) Limited in the six years prior to December 11, 2008 (the date proceedings were commenced against BLMIS) and that these are avoidable and recoverable under the U.S. Bankruptcy Code and New York law. The amount that the Madoff Trustee is currently seeking to recover from NIP is approximately $24.4 million plus interest. In March 2013, Banca Monte dei Paschi di Siena SpA (“MPS”) issued a claim in the Italian Courts against (1) two former directors of MPS and (2) NIP. MPS alleged that the former directors improperly caused MPS to enter into certain structured financial transactions with NIP in 2009 (“Transactions”) and that NIP acted fraudulently and was jointly liable for the unlawful conduct of MPS’s former directors. MPS claimed damages of not less than EUR 1.1 billion. In March 2013, NIP commenced a claim against MPS in the English Courts. The claim was for declaratory relief confirming that the Transactions remained valid and contractually binding. MPS filed and served its defence and counterclaim to these proceedings in March 2014. MPS alleged in its counterclaim that NIP was liable to make restitution of a net amount of approximately EUR 1.5 billion, and sought declarations regarding the illegality and invalidity of the Transactions. On September 23, 2015, NIP entered into a settlement agreement with MPS to terminate the Transactions. NIP believes that the Transactions were conducted legally and appropriately, and does not accept the allegations made against it or admit any wrongdoing. Taking into account the views of relevant European financial authorities and the advice provided by external experts, NIP considered it to be in its best interests to reach a settlement in relation to this matter. As part of the agreement, the Transactions were unwound at a discount of EUR 440 million in favour of MPS and the civil proceedings between MPS and NIP in Italy and England, respectively, will no longer be pursued. Pursuant to the settlement agreement MPS and NIP applied to the Italian Courts to discontinue the proceedings brought by MPS against NIP. These proceedings have since been discontinued. In April 2013, an investigation was commenced by the Public Prosecutor’s office in Siena, Italy, into various allegations against MPS and certain of its former directors, including in relation to the Transactions. The investigation was subsequently transferred to the Public Prosecutor of Milan. On April 3, 2015, the Public Prosecutor’s office in Milan issued a notice concluding its preliminary investigation. The Public Prosecutor was seeking to indict MPS, three individuals from MPS’s former management, NIP and two former NIP employees for, among others, the offences of false accounting and market manipulation in relation to MPS’s previous accounts. The preliminary hearing at which the Milan criminal court considered whether or not to grant the indictment concluded on October 1, 2016, the Judge ordering the trial of all individuals and banks involved except for MPS (which entered into a plea bargaining agreement with the Public Prosecutor). The trial commenced in December 2016. As part of these proceedings, a number of civil claimants have been permitted to bring damages claims against a number of entities and individuals, including NIP. On November 8, 2019, the court delivered its oral verdict, finding two former employees of NIP guilty of false accounting, market manipulation and obstructing the supervisory activities of CONSOB and that NIP had breached Italian corporate liability legislation. In so doing it imposed a fine of EUR 3.45 million on NIP as well as ordering confiscation of EUR 88 million. On May 12, 2020, the court issued the detailed reasoning for the verdict (including the rationale for the penalties imposed). NIP appealed the decision to the Milan Court of Appeal. On May 6, 2022, the Milan Court of Appeal delivered its oral verdict, overturning the first instance judgment and acquitting the two former employees of NIP of all charges. The court also overturned the first instance judgment in respect of NIP and quashed the EUR 3.45 million fine and EUR 88 million confiscation order imposed on NIP. The detailed reasoning for the verdict was made available on October 3, 2022. In November 2022, the Public Prosecutor appealed the decision to the Supreme Court. In addition, NIP is involved in a number of separate civil or administrative matters relating to the Transactions including those described further below. In January 2018, a claim before the Italian Courts brought by two claimants, Alken Fund Sicav (on behalf of two Luxembourg investment funds Alken Fund European Opportunities and Alken Fund Absolute Return Europe) and Virmont S.A. (formerly, Alken Luxembourg S.A, the funds’ management company) (collectively referred to as “Alken”) was served on NIP. The claim was made against NIP, MPS, four MPS former directors and a member of MPS’s internal audit board, and sought monetary damages of approximately EUR plus interest, as well as non-monetary In May 2019, a claim before the Italian Courts brought by York Global Finance Offshore BDH (Luxembourg) Sàrl and a number of seemingly related funds was served on NIP. The claim is made against NIP, MPS, two MPS former directors and a member of MPS’s internal audit board, and seeks monetary damages of approximately EUR 186.7 million plus interest, as well as non-monetary the Judge. Additionally , NIP was served by the Commissione Nazionale per le Società e la Borsa (“CONSOB”, the Italian financial regulatory authority) with a notice commencing administrative sanction proceedings for market manipulation in connection with the Transactions. In relation to the Transactions, the notice named MPS, three individuals from MPS’s former management and two former NIP employees as defendants, whereas NIP was named only in its capacity as vicariously liable to pay any fines imposed on the former NIP employees. On May 22, 2018 CONSOB issued its decision in which it levied EUR 100,000 fines in relation to each of the two former NIP employees. In addition, CONSOB decided that the two employees did not meet the necessary Italian law integrity requirements to perform certain senior corporate functions, for a period of three months and six months respectively. NIP was vicariously liable to pay the fines imposed on its former employees. NIP paid the fines and appealed the decision to the Milan Court of Appeal. In December 2020, the Court of Appeal annulled the CONSOB decision against NIP. CONSOB has appealed the Court of Appeal’s decision to the Italian Supreme Court. In June 2016 and August 2016, Nomura International (Hong Kong) Limited (“NIHK”) and Nomura Special Investments Singapore Pte Limited (“NSIS”) were respectively served with a complaint filed in the Taipei District Court against NIHK, NSIS and certain individuals by Cathay United Bank, Co., Ltd., Taiwan Cooperative Bank Ltd., Chang Hwa Commercial Bank Ltd., Taiwan Business Bank Ltd., KGI Bank and Hwatai Bank Ltd. (collectively, “Syndicate Banks”). The Syndicate Banks’ complaint relates to a $60 million syndicated term loan to a subsidiary of Ultrasonic AG that was arranged by NIHK, and made by the Syndicate Banks together with NSIS. The Syndicate Banks’ allegations in the complaint included allegations that NIHK failed to comply with its fiduciary duties to the lenders as the arranger of the loan and the Syndicate Banks sought to recover approximately $48 million in damages, plus interest. By judgment dated June 2, 2022, the Taipei District Court dismissed the Syndicate Banks’ claims in entirety. On July 4, 2022, a Statement of Appeal was filed by 5 of the 6 Syndicate Banks (Cathay United Bank Co., Ltd., Taiwan Cooperative Bank Ltd., Chang Hwa Commercial Bank Ltd., Taiwan Business Bank Ltd. and Hwatai Bank Ltd., together the “Appellants”), indicating the Appellants’ intention to appeal the Taipei District Court decision to the Taiwan High Court. The claim amount for the appeal was approximately million in damages, plus interest. The Appellants’ appeal was dismissed on August 30, 2022. The Taipei District Court judgment dated June 2, 2022, dismissing the Syndicate Banks’ claims, became final and binding on September 19, 2022. On May 20, 2021, NIP and the Company were named as addressees in a decision issued by the European Commission in which NIP, the Company and various other third party banks have been found to have infringed EU competition law in connection with their activity in the primary and secondary markets for European Government Bonds (“EGB”). The European Commission found that the infringement consisted of anticompetitive agreements and/or concerted practices in the EGB sector in breach of EU competition law and fined NIP and the Company approximately EUR 129.6 million. In August 2021, NIP and the Company appealed the decision. The fine has been provisionally paid, as is required, pending the outcome of NIP and the Company’s appeal. NIP and Nomura Securities International, Inc. (“NSI”) were named as defendants in a class action filed in the United States District Court for the Southern District of New York alleging violations of U.S. antitrust law in relation to the alleged manipulation of the primary and secondary markets for EGB. NSI has been dismissed from the action. Additionally, NIP and NSI were named as defendants in a separate class action filed in the Toronto Registry Office of the Federal Court of Canada alleging violations of Canadian competition law relating to the alleged manipulation of the market for supranational, sub-sovereign Nomura is responding to requests for information from the U.S. Commodity Futures Trading Commission (“CFTC”) in relation to swap trading related to bond issuances. On February 1, 2021, the CFTC filed a civil enforcement action against a Nomura employee and charged him with violating the anti-fraud, price manipulation and false statements provisions of the Commodity Exchange Act in relation to a 2015 interest rate swap transaction. Nomura also responded to requests for information from the CFTC in relation to compliance with records preservation requirements relating to the use of non-Nomura approved messaging platforms for business communications a penalty non-monetary NSI also responded to requests for information from the Securities and Exchange Commission (“SEC”) in connection with an investigation of compliance with records preservation requirements relating to the use of non-Nomura a penalty non-monetary The SEC and the United States Department of Justice (“DOJ”) investigated past activities of several former employees of NSI in respect of commercial and residential mortgage-backed securities transactions in the secondary market. In July 2019, NSI entered into settlements with the SEC concerning its supervision of certain former employees, and the investig ation has conc fully. In September 2017 and November 2017, NIHK and NSIS were respectively served with a complaint filed in the Taipei District Court against NIHK, NSIS, China Firstextile (Holdings) Limited (“FT”) and certain individuals by First Commercial Bank, Ltd., Land Bank of Taiwan Co., Ltd., Chang Hwa Commercial Bank Ltd., Taishin International Bank, E.Sun Commercial Bank, Ltd., CTBC Bank Co., Ltd., Hwatai Bank, Ltd. and Bank of Taiwan (collectively, “FT Syndicate Banks”). The FT Syndicate Banks’ complaint relates to a $100 million syndicated term loan facility to borrower FT that was arranged by NIHK, and made by the FT Syndicate Banks together with NSIS. The FT Syndicate Banks’ allegations in the complaint include tort claims under Taiwan law against the defendants. The FT Syndicate Banks seek to recover approximately $68 million in damages , In August 2017, the Cologne public prosecutor in Germany notified NIP that it is investigating possible tax fraud by individuals who worked for the Nomura Group in relation to the historic planning and execution of trading strategies around dividend record dates in certain German equities (known as “cum/ex” trading) and in relation to filings of tax reclaims in 2007 to 2012. During the fiscal year ended March 31, 2020, Nomura Group became aware that certain of those individuals would be the subject of investigative proceedings in Germany. NIP and another entity in the Nomura Group are cooperating with the investigation, including by disclosing to the public prosecutor certain documents and trading data, and Nomura Group premises in Frankfurt were raided by the public prosecutor in April 2023 for the purpose of obtaining additional data and documents. It appears that the investigation has expanded including to also now encompass cum/cum trading strategies in certain German equities. If the investigation involving Nomura Group entities and former individuals proceeds to trial, the individuals could face criminal sanctions and Nomura Group entities could face administrative sanctions such as administrative fines or profit confiscation orders. Stichting Vestia, a Dutch housing association and former counterparty, asserted a claim against NIP relating to derivative transactions entered into between Vestia and NIP between 2009 and 2011. On February 1, 2022, Vestia commenced proceedings against NIP in the English Courts. The proceedings alleged that the transactions were void because Vestia lacked the capacity and/or the authority to enter into them. Vestia sought restitution of a EUR In the context of a secured financing and the enforcement of the related pledge agreements following events of default attributable to the counterparty, on February 8, 2022, two former pledgors served a formal notice stating their intention to commence legal proceedings against Nomura European Investment Limited (“NEI”) as lender and NIP as security agent. The pledgors alleged that there had been certain valuation errors in relation to enforcement of the related pledge agreements and sought compensation from NEI or, alternatively, from NIP. On November 9, 2022, NEI and NIP entered into a settlement agreement with the pledgors to resolve the potential claim with no admission of liability or wrongdoing. In August and October 2022, Nomura Financial Advisory and Securities (India) Private Limited (“NFASI”) was served with two commercial suits filed with the Bombay High Court against NFASI and other parties. The lawsuits relate to the same equity disposal where the plaintiffs were two of the sellers and NFASI acted as financial advisor to the sellers, and include allegations that NFASI failed to comply with its duties as financial advisor. The total claim amounts in the suits are approximately INR Guarantees— In the normal course of business, Nomura enters into various guarantee arrangements with counterparties in the form of standby letters of credit and other guarantees, which generally have a fixed expiration date. In addition, Nomura enters into certain derivative contracts that meet the accounting definition of a guarantee, namely derivative contracts that contingently require a guarantor to make payment to a guaranteed party based on changes in an underlying that relate to an asset, liability or equity security held by a guaranteed party. Since Nomura does not track whether its clients enter into these derivative contracts for speculative or hedging purposes, Nomura includes relevant information about these derivative contracts that could meet the accounting definition of guarantees in the disclosure below. For information about the maximum potential amount of future payments that Nomura could be required to make under these derivative contracts, the notional amount of contracts has been disclosed, except for certain derivative contracts, such as written interest rate caps and written currency options, the maximum potential payout amount cannot be estimated, as increases in interest or foreign exchange rates in the future could be theoretically unlimited. The notional amounts do not represent anticipated losses from these derivatives contracts. As Nomura measures all derivative contracts at fair value, carrying value is considered the best indication of probability of payment and performance risks for these derivative contracts. Nomura may also reduce net exposures to certain of these contracts by entering into offsetting transactions or by entering into contracts that hedge the market risks related to these derivative contracts. The following table presents information on Nomura’s derivative contracts that could meet the accounting definition of a guarantee and standby letters of credit and other guarantees.

Geographic information— Nomura’s identifiable assets, revenues and expenses are generally allocated based on the country of domicile of the legal entity providing the service. However, because of the integration of the global capital markets and the corresponding global nature of Nomura’s activities and services, it is not always possible to make a precise separation by location.

Accounting Policies [Abstract] | |
Description of business | Description of business— Nomura Holdings, Inc. (“Company”) and its broker-dealer, banking and other financial services subsidiaries provide investment, financing and related services to individual, institutional and government clients on a global basis. The Company and other entities in which it has a controlling financial interest are collectively referred to as “Nomura” within these consolidated financial statements. Nomura operates its business through various divisions based upon the nature of specific products and services, its main client base and its management structure. On April 1, 2021, the Asset Management Division and the Merchant Banking Division were combined and the Investment Management Division was established. Nomura reports operating results through three business segments: Retail, Investment Management, and Wholesale. In its Retail segment, Nomura provides investment consultation services mainly to individual clients in Japan. In its Investment Management segment, Nomura mainly provides various investment management services and investment solutions such as establishing and managing investment trusts, discretionary investment services for domestic and overseas investors, investment and management for investment corporation and for funds for institutional investors, and management of Tokumei kumiai (silent partnerships). In its Wholesale segment, Nomura engages in the sales and trading of debt and equity securities, foreign exchange contracts and derivatives globally, and provides investment banking services such as the underwriting and distribution of debt and equity securities as well as mergers and acquisitions and financial advisory. |
Basis of presentation | Basis of presentation— The accounting and financial reporting policies of Nomura conform to accounting principles generally accepted in the United States (“U.S. GAAP”) as applicable to broker-dealers. These consolidated financial statements include the financial statements of the Company and other entities in which it has a controlling financial interest. Nomura initially determines whether it has a controlling financial interest in an entity by evaluating whether the entity is a variable interest entity (“VIE”) under Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 810 “ Consolidation For entities other than VIEs, Nomura is generally determined to have a controlling financial interest in an entity when it owns a majority of the voting interests. Equity investments in entities in which Nomura has significant influence over operating and financial decisions (generally defined as a holding of 20 to 50 percent of the voting stock of a corporate entity, or at least 3 percent of a limited partnership) are accounted for under the equity method of accounting (“equity method investments”) and reported within Other assets — Investments in and advances to affiliated companies Financial Instruments Trading assets, Private equity and debt investments or Other assets — Other Equity investments in which Nomura has neither control nor significant influence are carried at fair value, with changes in fair value recognized through the consolidated statements of income and reported within Trading assets, Private equity and debt investments or Other assets — Other Certain consolidated entities are investment companies under ASC 946 “ Financial Services — Investment Companies The Company’s principal subsidiaries include Nomura Securities Co., Ltd. (“NSC”), Nomura Securities International, Inc. (“NSI”), Nomura International plc (“NIP”) and Nomura Financial Products & Services, Inc. (“NFPS”). All material intercompany transactions and balances have been eliminated on consolidation. |
Use of estimates | Use of estimates— Nomura uses accounting estimates to prepare these consolidated financial statements and they require difficult, subjective and complex judgments by management. Such estimates determined by management to be material include estimates regarding the fair value of financial instruments and litigation provisions. Estimates, by their nature, are based on underlying assumptions which require management judgment and depend on the extent of available information. Actual results in future periods may differ from current estimates, which could have a material impact on these consolidated financial statements. Various references are made throughout the notes to these consolidated financial statements where critical accounting estimates based on management judgment have been made, the nature of the estimates, the underlying assumptions made by management used to derive those estimates and how these estimates affect the amounts reported in these consolidated financial statements. |
Fair value of financial instruments | Fair value of financial instruments— A significant amount of Nomura’s financial assets and financial liabilities are carried at fair value, with changes in fair value recognized through the consolidated statements of income and/ or the consolidated statements of comprehensive income. Use of a fair value measurement is either specifically required under U.S. GAAP or Nomura makes an election to use a fair value measurement for certain eligible items under the fair value option. Other financial assets and financial liabilities are carried at fair value on a nonrecurring basis, where the primary measurement basis is not fair value. Fair value is only used in specific circumstances after initial recognition, such as to measure impairment. In both cases, fair value is generally determined in accordance with ASC 820 “ Fair Value Measurements and Disclosures Fair value measurements The fair values of financial assets and financial liabilities of consolidated VIEs which meet the definition of collateralized financing entities are both measured using the more observable fair value of the financial assets and financial liabilities. |
Allowance for current expected credit losses | Allowance for current expected credit losses— Management recognizes allowance for current expected credit losses on financial assets not carried at fair value and certain off-balance “Financial Instruments – Credit Losses” Current expected credit losses are calculated over the expected life of the financial instruments in scope of the requirements on an individual or a portfolio basis, considering all relevant, reasonable and supportable information available about the collectability of cash flows, including information about past events, current conditions and future forecasts. Accrued interest receivables are excluded from the amortized cost basis of financing receivables when calculating current expected credit losses. The methodology used by Nomura to determine allowances for current expected credit losses in accordance with the current expected credit losses impairment model (“CECL impairment model”) primarily depends on the nature of the financial instrument and whether certain practical expedients permitted by ASC 326 are applied by Nomura. Allowances for current expected credit losses against recognized financial instruments are reported in the consolidated balance sheets within Allowance for credit losses off-balance Other liabilities Other expenses. See Note 7 “Financing receivables” |
Transfers of financial assets | Transfers of financial assets— Nomura accounts for the transfer of a financial asset as a sale when Nomura relinquishes control over the asset by meeting the following conditions: (a) the asset has been isolated from the transferor (even in bankruptcy or other receivership), (b) the transferee has the right to pledge or exchange the asset received, or if the transferee is an entity whose sole purpose is to engage in securitization or asset-backed financing activities, if, the holders of its beneficial interests have the right to pledge or exchange the beneficial interests held and (c) the transferor has not maintained effective control over the transferred asset. In connection with its securitization activities, Nomura utilizes special purpose entities (“SPEs”) to securitize commercial and residential mortgage loans, government and corporate securities or other types of financial assets. Nomura’s involvement with SPEs includes structuring and underwriting, distributing and selling debt instruments and beneficial interests issued by SPEs to investors. Nomura derecognizes financial assets transferred in securitizations provided that Nomura has relinquished control over such assets and does not consolidate the SPE. Nomura may obtain or retain an interest in the financial assets, including residual interests in the SPEs dependent upon prevailing market conditions. Any such interests are carried at fair value and reported within Trading assets Revenue —Net gain on trading |
Foreign currency translation | Foreign currency translation— The financial statements of the Company’s subsidiaries and operations are measured using their functional currency which is the currency of the primary economic environment in which the entity operates. All assets and liabilities of subsidiaries and operations which have a functional currency other than Japanese Yen are translated into Japanese Yen at exchange rates at the balance sheet date, and all revenue and expenses are translated at the average exchange rates for the respective years and the resulting translation adjustments are reported within Accumulated other comprehensive income (loss) Foreign currency assets and liabilities are translated at exchange rates at the balance sheet date and the resulting translation gains or losses are credited or charged to the consolidated statements of income. |
Revenue from services provided to customers | Revenue from services provided to customers— Nomura earns revenue through fees and commissions from providing financial services to customers across all three business divisions. These services primarily include trade execution and clearing services, distribution of fund unit services, financial advisory services, underwriting and distribution services and asset management services. Revenue is recognized when or as the client obtains control of the service provided by Nomura which depends on when each of the key distinct substantive promises made by Nomura within the contract with the client (“performance obligations”) are satisfied. Such performance obligations are generally satisfied at a particularly point in time or, if certain criteria are met, over a period of time. Revenue from providing distribution of fund units and clearing services is reported in the consolidated statements of income within Revenue — Commissions, Revenue — Asset management and portfolio service fees Revenue — Fees from investment banking Costs to obtain or fulfill the underlying contract to provide services to a client are deferred as assets if certain criteria are met. These deferred costs, which are reported in the consolidated balance sheets within Other assets impaired |
Trading assets and trading liabilities | Trading assets and trading liabilities— Trading assets Financial assets are classified as being held for trading when any of the following criteria are met: • The financial assets are originated or acquired with the intention to generate profit through sale in the short-term; • The financial assets are part of a portfolio of identified financial instruments that are managed together for the purposes of short-term profit or arbitrage profit-taking; or • The financial assets are derivative assets. Trading liabilities Revenue — Net gain on trading Certain nonderivative trading liabilities are held to economically hedge the price risk of specific investments in equity securities held for operating purposes. Changes in fair value of these trading liabilities are reported within Revenue—Gain (loss) on investments in equity securities the |
Collateralized agreements and collateralized financing | Collateralized agreements and collateralized financing— Collateralized agreements Securities purchased under agreements to resell Securities borrowed Collateralized financing Securities sold under agreements to repurchase Securities loaned Reverse repurchase and repurchase agreements principally involve the buying or selling of securities under agreements with clients to resell or repurchase these securities to or from those clients, respectively. These transactions are generally accounted for as collateralized agreements or collateralized financing transactions and are recognized in the consolidated balance sheets at the amount for which the securities were originally acquired or sold. Certain reverse repurchase and repurchase agreements are carried at fair value through election of the fair value option. Nomura also enters into Gensaki Repo transactions which are the standard type of repurchase agreement used in Japanese financial markets. Gensaki Repo transactions contain margin requirements, rights of security substitution, and certain restrictions on the client’s right to sell or repledge the transferred securities. Gensaki Repo transactions are accounted for as collateralized agreements or collateralized financing transactions and are recognized on the consolidated balance sheets at the amount that the securities were originally acquired or sold. Securities borrowing and lending transactions are generally accounted for as collateralized agreements and collateralized financing transactions, respectively. These transactions are generally cash collateralized and are recognized on the consolidated balance sheets at the amount of cash collateral advanced or received. Allowances for current expected credit losses recognized against securities borrowing transactions are not significant due to an ongoing monitoring of collateral and the short expected life of these transactions. Where Nomura acts as lenders in securities borrowing and lending transactions and receives securities that can be sold or pledged as collateral, Nomura recognizes the securities received at fair value within Other assets — Other Other liabilities. See Note 7 “Financing receivables” Offsetting of collateralized agreements and collateralized financings Reverse repurchase agreements and repurchase agreements (including Gensaki Repo transactions) accounted for as collateralized agreements and collateralized financing transactions, respectively, entered into with the same counterparty and documented under a master netting agreement are offset in the consolidated balance sheets where the specific criteria defined by ASC 210-20 Balance Sheet —Offsetting 210-20”) close-out 210-20 Other secured borrowings Trading balances of secured borrowings Transfers and Servicing Long-term borrowings “Securitizations and Variable Interest Entities” “Borrowings” All Nomura-owned assets pledged to counterparties where the counterparty has the right to sell or repledge the securities, including collateral transferred under Gensaki Repo transactions, are reported parenthetically within Trading assets as Assets pledged See Note 5 “Collateralized transactions” |
Derivatives | Derivatives— Nomura uses a variety of derivatives, including futures, forwards, swaps and options, for both trading and non-trading Trading assets or Trading liabilities Short-term borrowings or Long-term borrowings Derivatives used for trading purposes Derivatives used for trading purposes, including bifurcated embedded derivatives, are carried at fair value with changes in fair value reported in the consolidated statements of income within Revenue — Net gain on trading Derivatives held for non-trading In addition to its trading activities, Nomura uses derivatives for other than trading purposes such as to manage risk exposures arising from recognized assets and liabilities, forecasted transactions and firm commitments. Derivatives held for non-trading Derivatives and Hedging Fair value hedges Nomura designates certain derivative as fair value hedges of interest rate risk and foreign exchange risk arising from specific financial liabilities and foreign currency denominated non-trading Interest expense Revenue — Other Net investment hedges Nomura designates certain derivatives as hedges of the net investment in foreign operations related to specific subsidiaries with non-Japanese Revenue — Other Accumulated other comprehensive income (loss) Economic expense hedges Nomura designates certain derivatives as economic expense hedges to manage equity price risk or foreign currency risk of certain expenses arising from forecasted transactions or firm commitments. Changes in fair value of these derivatives are reported in the same line item in the consolidated statements of income where expenses arising from the hedged transactions are reported. Offsetting of derivatives Derivative assets and liabilities with the same counterparty documented under a legally enforceable master netting agreement and the related cash collateral receivables and payables are presented on a net basis in the consolidated balance sheets where the specific criteria defined by ASC 210-20 Settlement-to-market Exchange traded and centrally cleared OTC derivatives typically involve daily variation margin payments and receipts which reflect changes in the fair value of the related derivatives. Such variation margin amounts are accounted for as either a partial settlement of the derivative or as a separate cash collateral receivable or payable depending on the legal form of the arrangement with the relevant central clearing counterparty. See Note 3 “ Derivatives and hedging activities |
Loans receivable | Loans receivable— Loans receivable are loans which management intends to hold for the foreseeable future. Loans receivable are either carried at fair value or at amortized cost. Interest earned on loans receivable is reported in the consolidated statements of income within Revenue — Interest and dividends Loans receivable carried at fair value Certain loans which are risk managed on a fair value basis are carried at fair value through election of the fair value option. Nomura makes this election to mitigate volatility in the consolidated statements of income caused by the difference in measurement basis that would otherwise exist between the loans and the derivatives used to risk manage those loans. Changes in the fair value of loans receivable carried at fair value are reported in the consolidated statements of income within Revenue — Net gain on trading Loans receivable carried at amortized cost Loans receivable which are not carried at fair value are carried at amortized cost. Amortized cost represents cost adjusted for deferred fees and direct costs, unamortized premiums or discounts on purchased loans and after deducting applicable allowances for current expected credit losses under ASC 326 which Nomura initially adopted from April 1, 2020. Loan origination fees, net of direct origination costs, are amortized to Revenue — Interest and dividends Modifications of loans receivable where the borrower is in financial difficulty and Nomura has granted a financial concession are typically accounted for as troubled debt restructurings (“TDRs”). See Note 7 “ Financing receivables |
Other receivables | Other receivables— Receivables from customers Receivables from other than customers These amounts are carried at contractual amounts due less any applicable allowance for current expected credit losses recognized under ASC 326. See Note 7 “ Financing receivables” |
Loan commitments | Loan commitments— Unfunded loan commitments written by Nomura are accounted for as either off-balance These loan commitments are generally accounted for in a manner consistent with the accounting for the loan receivable upon funding. Where the loan receivable will be classified as a trading asset or will be elected for the fair value option, the loan commitment is also generally carried at fair value, with changes in fair value reported in the consolidated statements of income within Revenue — Net gain on trading For loan commitments where the loan will be held for the foreseeable future and will not be elected for the fair value option, Nomura recognizes allowances for current expected credit losses in accordance with ASC 326. Loan commitment fees are generally deferred and recognized over the term of the loan when funded as an adjustment to yield. If drawdown of the loan commitment is considered remote, loan commitment fees are recognized over the commitment period as service revenue. See Note 7 “Financing receivables” |
Payables and deposits | Payables and deposits— Payables to customers Payables to other than customers failed-to-receive Deposits received at banks |
Office buildings, land, equipment and facilities | Office buildings, land, equipment and facilities— Office buildings, land, equipment and facilities, owned and held for use by Nomura are stated at cost, net of accumulated depreciation and amortization, except for land, which is stated at cost. Significant renewals and additions are capitalized at cost. Maintenance, repairs and minor renewals are expensed as incurred in the consolidated statements of income. Leases and subleases entered into by Nomura as either lessor or lessee are classified as either operating or finance leases on inception date in accordance with ASC 842 “Leases”. right-of-use Other assets—Office buildings, land, equipment and facilities Other liabilities Lease liabilities are initially measured at present value of the future minimum lease payments over the expected lease term. The future minimum lease payments are discounted using a relevant Nomura incremental borrowing rate as derived from information available at lease commencement date. The expected lease term is generally determined based on the contractual maturity of the lease, and adjusted for periods covered by options to extend or terminate the lease when Nomura is reasonably certain to exercise those options. ROU assets are initially measured at the amount of lease liabilities, and adjusted for any prepaid lease payments, initial direct costs incurred and any lease incentives received. After lease commencement date, for operating leases Nomura as lessee recognizes lease expense over the lease term generally on a straight-line basis within Occupancy and related depreciation Information processing and communications Depreciation and amortization charges of owned assets are generally computed using the straight-line method and recognized over the estimated useful lives of each asset. The estimated useful life of an asset takes into consideration technological change, normal deterioration and actual physical usage by Nomura. Leasehold improvements are depreciated over the shorter of their useful life or the term of corresponding lease. The estimated useful lives for significant asset classes are as follows: Office buildings 3 to 50 years Equipment and facilities 3 to 20 years Software 3 to 10 years Long-lived assets, including ROU assets and software assets but excluding goodwill and indefinite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the estimated future undiscounted cash flows generated by the asset is less than the carrying amount of the asset, a loss is recognized to the extent that the carrying value exceeds its fair value. See Note 8 “ Leases |
Investments in equity securities | Investments in equity securities— Nomura holds minority stakes in the equity securities of unaffiliated Japanese financial institutions and corporations in order to promote existing and potential business relationships. These companies often have similar investments in Nomura. Such cross-holdings are a customary business practice in Japan and provide a way for companies to manage shareholder relationships. These investments, which Nomura refers to as being held for operating purposes, are carried at fair value and reported within Other assets — Investments in equity securities Revenue — Gain (loss) on investments in equity securities |
Other non-trading debt and equity securities | Other non-trading Certain subsidiaries within Nomura hold debt securities and minority stakes in equity securities for non-trading Non-trading Other assets — Non-trading Other assets — Other Revenue — Other non-trading Revenue — Other |
Short-term and long-term borrowings | Short-term and long-term borrowings— Short-term borrowings are defined as borrowings which are due on demand, which have a contractual maturity of one year or less at issuance date, or which have a longer contractual maturity but which contain substantive features outside of Nomura’s control that allows the investor to demand redemption within one year from original issuance date, provided exercise of such features are not considered to be remote. Short-term and long-term borrowings primarily consist of commercial paper, bank borrowings, and certain structured notes issued by Nomura and SPEs consolidated by Nomura, and financial liabilities recognized in transfers of financial assets which are accounted for as financings rather than sales under ASC 860 (“secured financing transactions”). Of these financial liabilities, certain structured notes and secured financing transactions are accounted for at fair value on a recurring basis through election of the fair value option. Other short and long-term borrowings are carried at amortized cost. Structured notes are debt securities which contain embedded features (often meeting the accounting definition of a derivative) that alter the return to the investor from simply receiving a fixed or floating rate of interest to a return that depends upon some other variable(s) such as an equity or equity index, commodity price, foreign exchange rate, credit rating of a third party or more complex interest rate calculation. Structured borrowings are borrowings that have similar characteristics as structured notes. All structured notes and certain structured borrowings issued by Nomura are carried at fair value on a recurring basis through election of the fair value option. This blanket election for structured notes and certain structured borrowings are made primarily to mitigate the volatility in the consolidated statements of income caused by differences in the measurement basis for structured notes and the derivatives used to risk manage those positions and to generally simplify the accounting Nomura applies to these financial instruments. Changes in the fair value of structured notes elected for the fair value option are reported within Revenue — Net gain on trading Other comprehensive income See Note 10 “ Borrowings |
Income taxes | Income taxes— Deferred tax assets and liabilities are recognized to reflect the expected future tax consequences of operating loss carryforwards, tax credit carryforwards and temporary differences between the carrying amounts for financial reporting purposes and the tax bases of assets and liabilities based upon enacted tax laws and tax rates. Nomura recognizes deferred tax assets to the extent it believes that it is more likely than not that a benefit will be realized. A valuation allowance is established against deferred tax assets for tax benefits available to Nomura that are not deemed more likely than not to be realized. Deferred tax assets and deferred tax liabilities that relate to the same tax-paying Other assets — Other Other liabilities Nomura recognizes and measures unrecognized tax benefits based on Nomura’s estimate of the likelihood, based on technical merits, that tax positions will be sustained upon examination based on the facts and circumstances and information available at the end of each reporting period. Nomura adjusts the level of unrecognized tax benefits when there is more information available, or when an event occurs requiring a change. The reassessment of unrecognized tax benefits could have a material impact on Nomura’s effective tax rate in the period in which it occurs. Nomura reports income tax-related Income tax expense See Note 1 4 Income taxes |
Stock-based and other compensation awards | Stock-based and other compensation awards— Stock-based awards issued by Nomura to senior management and other employees are classified as either equity or liability awards depending on the terms of the award. Stock-based awards such as Stock Acquisition Rights (“SARs”) and Restricted Stock Units (“RSUs”) which are expected to be settled by the delivery of the Company’s common stock are classified as equity awards. For these awards, total compensation cost is generally fixed at the grant date and measured using the grant-date fair value of the award, net of any amount the employee is obligated to pay and estimated forfeitures. Stock-based awards such as Notional Stock Units (“NSUs”) and Collared Notional Stock Units (“CSUs”) which are expected to be settled in cash are classified as liability awards. Liability awards are remeasured to fair value at each balance sheet date, net of estimated forfeitures with the final measurement of cumulative compensation cost equal to the settlement amount. For both equity and liability awards, fair value is determined either by using option pricing models, the market price of the Company’s common stock or the price of the third party index, as appropriate. Compensation cost is recognized in the consolidated statements of income over the requisite service period, which generally is equal to the contractual vesting period. Where an award has graded vesting, compensation expense is recognized using the accelerated recognition method. Certain deferred compensation awards include “Full Career Retirement” (“FCR”) provisions which permit recipients of the awards to continue to vest in the awards upon voluntary termination or by claiming FCR during a pre-defined See Note 1 3 Deferred compensation awards |
Earnings per share | Earnings per share— The computation of basic earnings per share is based on the weighted average number of shares outstanding during the year. Diluted earnings per share reflects the assumed conversion of all dilutive securities based on the most advantageous conversion rate or exercise price available to the investors, and assuming conversion of convertible debt under the if-converted See Note 1 1 Earnings per share |
Cash and cash equivalents | Cash and cash equivalents— Nomura defines cash and cash equivalents as cash on hand and demand deposits with banks. |
Goodwill and intangible assets | Goodwill and intangible assets— Goodwill is recognized upon completion of a business combination as the difference between the purchase price and the fair value of the net assets acquired. Subsequent to initial recognition, goodwill is not amortized but is tested for impairment at a reporting unit level during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Nomura’s reporting units are at the same level as or one level below its business segments. Nomura tests goodwill of each separate reporting unit by initially qualitatively assessing whether events and circumstances indicate that it is more likely than not (i.e., greater than 50% likelihood) that a reporting unit’s fair value is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the reporting unit is deemed not to be impaired and no further analysis is required. If it is more likely than not that fair value of the reporting unit is below its carrying value, a quantitative test is then performed. A goodwill impairment loss is recognized through the consolidated statements of income as the excess of the carrying amount of a reporting unit, including goodwill, over its fair value but limited to the total amount of goodwill allocated to the reporting unit. Intangible assets not subject to amortization (“indefinite-lived intangible assets”) are tested for impairment on an individual asset basis during the fourth quarter of each fiscal year, or more frequently during earlier interim periods if events or circumstances indicate there may be impairment. Similar to goodwill, Nomura tests an indefinite-lived intangible asset by initially qualitatively assessing whether events or circumstances indicate that it is more likely than not that the fair value of the intangible asset is less than its carrying amount. If such assessment indicates fair value is not less than the carrying value, the intangible asset is deemed not to be impaired and no further analysis is required. If it is more likely than not that the fair value of the intangible asset is below its carrying value, the current estimated fair value of the intangible asset is compared with its carrying value. An impairment loss is recognized if the carrying value of the intangible asset exceeds its estimated fair value. Intangible assets with finite lives (“finite-lived intangible assets”) are amortized over their estimated useful lives and tested for impairment either individually or with other assets (“asset group”) when events and circumstances indicate that the carrying value of the intangible asset (or asset group) may not be recoverable. A finite-lived intangible asset is impaired when its carrying amount or the carrying amount of the asset group exceeds its fair value. An impairment loss is recognized only if the carrying amount of the intangible asset (or asset group) is not recoverable and exceeds its fair value. For both goodwill and intangible assets, to the extent an impairment loss is recognized, the loss establishes a new cost basis for the asset which cannot be subsequently reversed. See Note 9 Other assets — Office buildings, land, equipment and facilities and Other / Other liabilities” |
Equity method investments | Equity method investments— Nomura’s equity method investments are tested in their entirety for other-than-temporary impairment when there is an indication of impairment. The underlying assets associated with the equity method investments, including goodwill, are not tested separately for impairment. If we conclude that an other-than-temporary impairment exists, the investment is written down to its fair value, which establishes a new cost basis to be used prospectively for application of the equity method investments. |
Employee benefit plans | Employee benefit plans— Nomura provides certain eligible employees with various benefit plans, including pensions and other post-retirement benefits. These benefit plans are classified as either defined benefit plans or defined contribution plans. Plan assets and benefit obligations, as well as the net periodic benefit cost of a defined benefit pension or post-retirement benefit plan, are recognized based on various actuarial assumptions such as discount rates, expected return on plan assets and future compensation levels at the balance sheet date. Actuarial gains and losses in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets and unrecognized prior service costs or credits are amortized to net periodic benefit cost on a straight-line basis over the average remaining service life of active employees expected to receive benefits. The overfunded or underfunded status of a plan is reported within Other assets — Other Other liabilities Other comprehensive income (loss) net-of-tax The net periodic pension and other benefit cost of defined contribution plans is recognized within Compensation and benefits See Note 12 “ Employee benefit plans |

Future accounting developments | Future accounting developments— The following table presents a summary of new authoritative accounting pronouncements relevant to Nomura which will be adopted on or after April 1, 2023, the expected date of adoption by Nomura and whether the new accounting pronouncement may have a material impact on these consolidated financial statements: Pronouncement Summary of new guidance Expected adoption Effect on these ASU 2022-02 “Financial instruments – Credit losses (Topic 326): Troubled debt restructurings and vintage disclosures” • Eliminates specific recognition and measurement guidance for troubled debt restructurings (“TDRs”). Single guidance to be applied to all modifications when determining whether a modification results in a new receivable or a continuation of an existing receivable; • Requires to use a discounted cash flow (“DCF”) or reconcilable method for measurement of current expected credit losses for modified receivables is removed; where a DCF method is used for the measurement, an effective interest rate (EIR) derived from the modified contractual terms should be applied; • Enhances disclosures by creditors for modifications of receivables from debtors experiencing financial difficulty in the form of principal forgiveness, an interest rate reduction, other-than-insignificant payment delay or term extension; • Augments the current requirements for public business entity creditors to disclose current-period gross write-offs by year of origination (i.e., the vintage year) for financing receivables and net investments in leases. Nomura will adopt the amendments from April 1, 2023. No material financial impact expected unless a significant number of TDRs occur in the future. Certain disclosures about modification of receivables and write-offs will be updated or removed. Pronouncement Summary of new guidance Expected adoption Effect on these ASU 2022-03 “Fair value measurement (Topic 820)” • Clarifies that a contractual sale restriction is an entity-specific characteristic and therefore should not be considered in the fair value measurement of an equity security. • Enhances disclosures for fair value of investments in equity securities subject to contractual sale restrictions, nature and remaining duration of the restrictions and circumstances that could cause a lapse in the restrictions. Nomura currently plans to adopt the amendments from April 1, 2024. No material financial impact expected. |

(2) Weighted average information for non-derivatives (3) Nomura has not provided weighted average information for derivatives as unlike cash products the risk on such products is distinct from the balance sheet value and is subject to netting. (4) The above table only considers the impact of an increase in each significant unobservable valuation input on the fair value measurement of the financial instrument. However, a decrease in the significant unobservable valuation input would have the opposite effect on the fair value measurement of the financial instrument. For example, if an increase in a significant unobservable valuation input would result in a lower fair value measurement, a decrease in the significant unobservable valuation input would result in a higher fair value measurement. (5) The impact of an increase in the significant unobservable valuation input on the fair value measurement for a derivative assumes Nomura is long risk to the input e.g., long volatility. Where Nomura is short such risk, the impact of an increase would have a converse effect on the fair value measurement of the derivative. (6) Consideration of the interrelationships between significant unobservable valuation inputs is only relevant where more than one unobservable valuation input is used to determine the fair value measurement of the financial instrument.

[1]Consideration of the interrelationships between significant unobservable valuation inputs is only relevant where more than one unobservable valuation input is used to determine the fair value measurement of the financial instrument.[2]Range information is provided in percentages, coefficients and multiples and represents the highest and lowest level significant unobservable valuation input used to value that type of financial instrument. A wide dispersion in the range does not necessarily reflect increased uncertainty or subjectivity in the valuation input and is typically just a consequence of the different characteristics of the financial instruments themselves.[3]The above table only considers the impact of an increase in each significant unobservable valuation input on the fair value measurement of the financial instrument. However, a decrease in the significant unobservable valuation input would have the opposite effect on the fair value measurement of the financial instrument. For example, if an increase in a significant unobservable valuation input would result in a lower fair value measurement, a decrease in the significant unobservable valuation input would result in a higher fair value measurement.[4]The impact of an increase in the significant unobservable valuation input on the fair value measurement for a derivative assumes Nomura is long risk to the input e.g., long volatility. Where Nomura is short such risk, the impact of an increase would have a converse effect on the fair value measurement of the derivative.[5]Nomura has not provided weighted average information for derivatives as unlike cash products the risk on such products is distinct from the balance sheet value and is subject to netting.[6]Weighted average information for non-derivatives is calculated by weighting each valuation input by the fair value of the financial instrument.[7]Derivatives which contain multiple types of risk are classified based on the primary risk type of the instrument.[8]Valuation techniques and unobservable valuation inputs in respect of equity securities reported within Other assets in the consolidated balance sheets. |

[1]The U.K. Finance Act 2021, enacted on June 10, 2021, increases the headline U.K. corporation tax rate from 19% to 25% on April 1, 2023. Deferred tax assets and liabilities as of the balance sheet date are calculated by reference to the most appropriate enacted rates as of March 31, 2022. As a result of the change in closing deferred tax rate, Nomura recognized a movement in Effect of changes in foreign tax laws of ¥36 billion (which decreased Nomura’s effective tax rate by 16.0%), which was offset by a movement in Changes in deferred tax valuation allowances of ¥36 billion (which increased Nomura’s effective tax rate by 16.0% ) during the year ended March 31, 2022.[2]Tax benefit recognized on the outside basis differences for investment in subsidiaries and affiliates during the year ended March 31, 2021 of approximately ¥21 billion (which decreased Nomura’s effective tax rate by 9.1%) arises from the recognition of deferred tax assets from the decision and commitment of Nomura management to liquidate a certain wholly-owned subsidiary within Nomura in the foreseeable future. The valuation allowances of ¥3 billion have been recognized against these deferred tax assets, the impact of which are reported in Changes in deferred tax valuation allowances for the same period. |
