Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	Kura Sushi USA, Inc. (the “Company”) is a technology-enabled Japanese restaurant concept that provides guests with a distinctive dining experience by serving authentic Japanese cuisine through an engaging revolving sushi service model, which the Company refers to as the “Kura Experience.” Kura Sushi encourages healthy lifestyles by serving freshly prepared Japanese cuisine using high-quality ingredients that are free from artificial seasonings, sweeteners, colorings, and preservatives. Initial Public Offering On August 5, 2019, the Company completed the initial public offering of its Class A common stock at a public offering price of $14.00 per share. The Company issued 3,335,000 shares, including 435,000 shares sold to the underwriters pursuant to their over -allotment option. After underwriter discounts and commissions and offering expenses, net proceeds from the offering were $38.6 million. No payments were made by the Company to directors, officers or persons owning 10% or more of the Company’s common stock or to their associates, or to the Company’s affiliates. Follow-On Offering On July 23, 2021, the Company completed a follow-on offering and sold an aggregate of 1,265,000 shares of Class A common stock, including the exercise in full of the underwriters’ option to purchase 165,000 additional shares, at the price of $45.00 per share less an underwriting discount of $2.48 per share. The Company received aggregate net proceeds of $53.5 million after deducting the underwriting discounts and commissions and offering expenses payable by the Company. The Company used a portion of the net proceeds to repay all of the $17.0 million borrowings outstanding under the Company’s credit facility with Kura Japan, with the remaining proceeds to be used to support new unit growth, for working capital and general corporate purposes. No payments were made by the Company to directors, officers or persons owning 10% or more of the Company’s common stock or to their associates, or to the Company’s affiliates. Effects of COVID-19 The negative effects of the COVID-19 pandemic on the Company’s business have been significant. In March 2020, the World Health Organization declared the novel strain of coronavirus COVID-19 a global pandemic. This contagious virus, which has continued to spread, has adversely affected workforces, customers, economies and financial markets globally. In response to this outbreak, many state and local authorities mandated the temporary closure of non-essential businesses and dine-in restaurant activity or limited indoor dining capacities. COVID-19 and the government measures taken to control it have caused a significant disruption to the Company’s business operation. As of fiscal year-end August 31, 2021, the Company had all of its 32 restaurants operating at 100% indoor dining capacity. In October 2021, the Company opened one new restaurant in San Francisco, California. As of the filing date of this Annual Report on Form 10-K, the Company had all of its 33 restaurants operating at 100% indoor dining capacity. In response to the ongoing COVID-19 pandemic, the Company has prioritized taking steps to protect the health and safety of its employees and customers. The Company has maintained cleaning and sanitizing protocols of its restaurants and has implemented additional training and operational manuals for its restaurant employees, as well as increased handwashing procedures. The Company also provides each restaurant employee with face masks and gloves, and requires each employee to pass a health screening process, which includes a temperature check, before the start of each shift. The reduced capacities at the Company’s restaurants have caused a substantial decline in its sales in the most recently completed fiscal year compared to pre-pandemic levels. In response to the ongoing challenges posed by the COVID-19 pandemic, the Company is focused on maximizing its in-restaurant dining capacity as permitted by the jurisdictions where it operates, continuing to provide a safe environment for its employees and customers, maintaining its operational efficiencies as much as possible and preserving its liquidity. Currently, with the lift of all indoor dining restrictions at all of its restaurants, the Company has experienced a staffing shortage and has provided certain employee retention and new hire bonuses. In line with the Company’s long-term growth strategy, the Company expects to continue to open new restaurants at locations where it believes they have the potential to achieve profitability. Recent Events Concerning the Company’s Financial Position On April 10, 2020, the Company and Kura Sushi, Inc. (“Kura Japan”), the majority stockholder of the Company, entered into a Revolving Credit Agreement Under the provisions of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) signed into law on March 27, 2020 and the subsequent extension of the CARES Act, the Company was eligible for a refundable employee retention credit subject to certain criteria. The Company recognized a $10.3 million employee retention credit and a $1.8 million employee retention credit during the fiscal years 2021 and 2020, respectively. For fiscal year 2021, $9.3 million is included in labor and related costs and $1.0 million is included in general and administrative expenses in the statements of operations. For fiscal year 2020, $1.7 million is included in labor and related costs and $0.1 million is included in general and administrative expenses in the statements of operations. The Company has filed for refunds of the employee retention credits and subsequent to August 31, 2021 and as of the date of this Annual Report on Form 10-K, has received $8.0 million in refunds and cannot reasonably estimate when it will receive any or all of the remaining refunds. As of August 31, 2021, the Company is no longer eligible to receive refundable employee retention credits. The Company has received rent concessions from its landlords for certain of its restaurants in the form of rent abatements and rent deferrals which were immaterial for fiscal year 2021. Due to a staffing shortage, the Company provided certain employee retention and new hire bonuses totaling $1.2 Due to the impact of COVID-19, the Company assessed its long-lived assets for potential impairment, which resulted in no impairment charges recorded as of August 31, 2021. The Company also assessed the realizability of its deferred tax assets and, as of August 31, 2021, had a total valuation allowance of $8.4 million. See “Note 10. Income Taxes”.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2—Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company’s fiscal year begins on September 1 and ends on August 31 and references made to “fiscal year 2021”, “fiscal year 2020” and “fiscal year 2019” refer to the Company’s fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods presented. Significant items subject to such estimates include asset retirement obligations, stock-based compensation, the useful lives of assets, the assessment of the recoverability of long-lived assets, and income taxes. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from those estimates and assumptions. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents. The Company maintains its cash and cash equivalents with financial institutions and, at times, the balance may exceed the Federal Deposit Insurance Corporation federally insured limits. The Company has never experienced any losses related to these balances. Concentration of Significant Suppliers The Company relies on third parties for specified food products and supplies. In instances where these parties fail to perform their obligations, the Company may be unable to find alternative suppliers. The Company is subject to supplier concentration risk as JFC International Inc., a subsidiary of Kikkoman Corporation and the Company’s largest supplier, accounted for 58% 27% 28% for fiscal year Segment Information Management has determined that the Company has one operating segment and therefore one reportable segment. The Company’s chief operating decision maker, its Chief Executive Officer, reviews financial performance and allocates resources. All of the Company’s sales are derived in the United States of America. Cash and Cash Equivalents Cash and cash equivalents consist primarily of cash on hand, deposits with banks, money market funds and term deposits. As of August 31, 2021 and August 31, 2020, cash equivalents were $36.1 and $8.8 million, respectively. Due to the short-term maturities and their relatively low interest rates, the carrying value of the money market funds approximates their fair value. Cash and cash equivalents are maintained at financial institutions with strong credit ratings. The Company considers all highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Accounts and Other Receivables Accounts and other receivables consist primarily of receivables from landlords for tenant allowances and credit card receivables. The Company does not extend credit to guests and thus does not have credit risk from guests. Accounts and other receivables balances are stated at the amounts management expects to collect from balances outstanding at fiscal year-end, and no allowance for doubtful accounts is recorded as of August 31, 2021 and August 31, 2020. Inventories Inventories consist of food and beverages and are stated at the lower of cost or net realizable value, with cost determined on an average cost basis. Property and Equipment Property and equipment consists of computer equipment, vehicles, software, furniture and fixtures, leasehold improvements and leased assets. Property and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization on property and equipment is calculated using the straight-line method over the estimated useful lives of the respective assets, ranging from three to 20 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the remaining lease term or estimated life of the improvements. The following table represents the various types of property and equipment and their respective useful lives: Property and Equipment Useful Life Computer equipment 3 – 5 years Vehicles 5 years Software 5 years Furniture and fixtures 10 years Leasehold improvements Shorter of useful life or remaining lease term Lease assets Fixed lease term Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to its estimated fair value. Liquor Licenses Liquor licenses are deemed to have indefinite useful lives and are subject to annual impairment testing. Liquor licenses are included in deposits and other assets in the accompanying balance sheets. Asset Retirement Obligations Asset retirement obligations (“ARO”) represents the estimated present value of future expenses the Company expects to incur at the end of a lease to restore the location to its original condition. The ARO is recorded as a liability at its estimated present value at inception with an offsetting increase in the carrying amount of the related property and equipment in the accompanying balance sheet. Periodic accretion of the discount of the estimated liability is recorded as interest expense in the accompanying statements of operations. Asset retirement obligations are amortized on a straight-line basis over the shorter of the remaining lease term or estimated life of the leasehold improvements. The Company’s ARO liability is $0.4 million and $0.3 million as of August 31, 2021 and August 31, 2020, respectively and is included in other liabilities in the accompanying balance sheets. Impairment of Long-lived Assets The Company assesses potential impairments of its long-lived assets, which includes property and equipment and operating lease right-of-use assets, in accordance with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360—Property, Plant and Equipment. An impairment test is performed on an annual basis or whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. In determining the recoverability of the asset value, an analysis is performed at the individual restaurant level. Assets are grouped at the individual restaurant level for purposes of the impairment assessment because a restaurant represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of an asset group is measured by a comparison of the carrying amount of an asset group to its estimated undiscounted forecasted restaurant cash flows expected to be generated by the asset group. Factors considered by the Company in estimating future cash flows include but are not limited to: significant underperformance relative to expected historical or projected future operating results; significant changes in the manner of use of the acquired assets; and significant negative industry or economic trends. The estimated undiscounted forecasted cash flows include assumptions made by management regarding certain items such as revenue, food and beverage costs, labor costs, occupancy costs, and other restaurant operating costs and therefore are subject to uncertainty as the Company’s actual results may differ from its estimates. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. The assumptions and estimated undiscounted forecasted cash flows used in the estimate have not changed materially during the year, and Income Taxes The provision for income taxes, income taxes payable, and deferred income taxes are determined using the asset and liability method. Deferred income tax assets and liabilities are determined based on temporary differences between the financial carrying amounts and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. The Company establishes a valuation allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income. Income tax expense or benefit is the income tax payable or refundable for the period, plus or minus the change during the period to deferred income tax assets and liabilities. The Company regularly evaluates the likelihood of realizing the benefit for income tax positions it has taken in federal and state filings by considering all facts, circumstances, and information available. For those benefits that the Company believes it is more likely than not will be sustained, it recognizes the largest amount it believes is cumulatively greater than 50% likely to be realized. Revenue Recognition Revenue from sales is recognized when food and beverages are sold to customers. Sales are presented net of discounts and sales taxes collected from customers. Sales Taxes Sales taxes are imposed by state, county, and city governmental authorities, collected from customers and remitted to the appropriate governmental agency. The Company’s policy is to record the sales taxes collected as a liability on the books and then remove the liability when the sales tax is remitted. There is no impact on the statements of operations as restaurant sales are recorded net of sales tax. Operating and Finance Leases At inception of a contract, the Company assesses whether the contract is a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lease classification, measurement, and recognition are determined at lease commencement, which is the date the underlying asset is available for use by the Company. The accounting classification of a lease is based on whether the arrangement is effectively a financed purchase of the underlying asset (finance lease) or not (operating lease). The Company has operating and finance leases for its corporate office, restaurant locations, office equipment, kitchen equipment and automobiles. The leases have remaining lease terms of less than 1 year to 20 years, some of which include options to extend the leases. For leases with renewal periods at the Company’s option, the Company determines the expected lease period based on whether the renewal of any options is reasonably assured at the inception of the lease. Operating leases are accounted for on the balance sheet with the right-of-use (“ROU”) assets and lease liabilities recognized in “Operating lease right-of-use assets,” “Operating lease liabilities - current" and "Operating lease liabilities - noncurrent" on the balance sheet, respectively. Finance leases are accounted for on the balance sheet with ROU assets and lease liabilities recognized in "Property and equipment – net,” “Finance lease - current" and "Finance lease - noncurrent" on the balance sheet, respectively. Lease assets and liabilities are recognized at the lease commencement date. All lease liabilities are measured at the present value of the lease payments not yet paid. To determine the present value of lease payments not yet paid, the Company estimates incremental borrowing rates corresponding to the maturities of the leases. As the Company has no outstanding debt, it estimates this rate based on prevailing financial market conditions, comparable company and credit analysis, and management judgment. ROU assets, for both operating and finance leases, are initially measured based on the lease liability, adjusted for initial direct costs, prepaid or deferred rent, and lease incentives. The operating lease ROU assets are subsequently measured at the carrying amount of the lease liability adjusted for initial direct costs, prepaid or accrued lease payments, and lease incentives. Depreciation of the finance lease ROU assets are subsequently calculated using the straight-line method over the shorter of the estimated useful lives or the expected lease terms and recorded in "Depreciation and amortization expense" on the statement of operations. The Company accounts for lease and non-lease components as a single component for its entire population of operating lease assets. The Company recognizes expense for these leases on a straight-line basis over the lease term. In addition to the fixed minimum payments required under the lease arrangements, certain leases require variable lease payments, such as common area maintenance, insurance and real estate taxes, which are recognized when the associated activity occurs. Additionally, contingent rental payments based on sales thresholds for certain of its restaurants are accrued based on estimated sales. Other Costs Other costs in restaurant operating costs in the accompanying statements of operations include utilities, repairs and maintenance, credit card fees, royalty payments, stock-based compensation for restaurant-level employees, and other restaurant-level expenses. The Company incurred $10.4 million, $6.7 million and $7.1 million in other costs for the fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively. Advertising Costs Advertising costs are expensed as incurred and are included in other costs in the accompanying statements of operations. The Company incurred $0.6 million, $0.3 million and $0.4 million in advertising expenses for the fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively. Fair Value Measurements The Company defines fair value as the exchange price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value measurement accounting guidance creates a fair value hierarchy to prioritize the inputs used to measure fair value into three categories. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement, where Level 1 is the highest and Level 3 is the lowest. The three levels are defined as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets. Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 – Observable inputs other than Level 1 prices, such as unadjusted quoted prices for similar assets or liabilities in active markets, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on the Company’s own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation. The Company’s financial statements include cash and cash equivalents, accounts and other receivables, accounts payable, accrued expenses and other current liabilities, and salaries and wages payable for which the carrying amounts approximate fair value due to their short-term maturity. The fair value of payments due to or from Kura Japan is not determinable due to its related-party nature. Stock-based Compensation Stock-based compensation consists of stock options issued to employees and non-employees. The Company measures and recognizes stock-based compensation for the estimated fair value of stock options based on the grant date fair value of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model and is impacted by the fair value of the Company’s common stock, as well as changes in assumptions regarding certain subjective variables. These variables include, but are not limited to, the expected common stock price volatility over the term of the stock option awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. For stock options that are based on a service requirement, the cost is recognized on a straight-line basis over the requisite service period, which is typically the vesting period. Stock options granted in fiscal year 2021 have vesting periods ranging from 12 months to 48 months. Stock options granted in fiscal year 2020 have vesting periods ranging from 9 months to 46 months. The majority of stock options granted in fiscal 2019 have a vesting period of approximately 45 months. Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) is the same as net income (loss) for all periods presented. Therefore, a separate statement of comprehensive income (loss) is not included in the accompanying financial statements. Earnings (Loss) Per Share Earnings (loss) per share is calculated by dividing net income (loss) by the weighted average shares outstanding during the period, without consideration of common stock equivalents. Diluted earnings per share assumes the conversion, exercise or issuance of all potential dilutive common stock equivalents outstanding for the period. For the purposes of this calculation, options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive. Diluted earnings per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method. Recently Adopted Accounting Pronouncements On September 1, 2019, the Company adopted ASU 2016-02, “Leases (Topic 842)” (“Topic 842”), along with related clarifications and improvements. As a result of the adoption of Topic 842, the accompanying balance sheets and fiscal years 2021 and 2020 statement of operations and statement of cash flows reflect the adoption; however, the fiscal year 2019 statement of operations and statement of cash flows are presented on the basis of ASC Topic 840: “Leases.” The adoption of Topic 842 had an immaterial impact on the statement of operations and statement of cash flows. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which is intended to simplify various aspects related to accounting for income taxes. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. ASU 2019-12 is effective for the Company beginning in fiscal year 2022. The Company is currently in the process of evaluating the effects of this pronouncement on its financial statements.

The total fair value of options vested was $0.7 million, $0.6 million, and $0.6 million for the fiscal years ended August 31, 2021, August 31, 2020, and August 31, 2019, respectively. As of August 31, 2021, unrecognized stock-based compensation of $4.1 million related to unvested stock options is expected to be recognized on a straight-line basis over a weighted average period of 3.1 years. Stock-based Compensation Expense Stock-based compensation for restaurant-level employees is included in other costs and stock-based compensation for corporate-level employees is included in general and administrative expenses in the statements of operations. The total stock-based compensation recognized under the Stock Incentive Plan in the statements of operations is as follows: Fiscal Years Ended August 31, 2021 2020 2019 (amounts in thousands) Other Costs $ 118 $ 86 $ 80 General and administrative expenses 1,291 774 510 Total stock-based compensation $ 1,409 $ 860 $ 590 Determination of Fair Value For the fiscal years ended August 31, 2021, August 31, 2020, and August 31, 2019, the fair value of stock options was estimated on the grant date using the Black-Scholes valuation model with the following assumptions: Fiscal Years Ended August 31, 2021 2020 2019 Expected term (in years) 5.50 - 6.11 5.23 - 5.98 5.96 Expected volatility 61.7% - 62.7% 48% - 58.5% 64 % Risk-free interest rate 0.47% - 1.16% 0.40% - 1.67% 2.77 % Dividend rate — — — Weighted average grant date fair value $ 16.66 $ 11.01 $ 6.91 Expected Term - The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For option grants that are considered to be “plain vanilla,” the Company determines the expected term using the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options. Expected Volatility - Since the Company does not have a trading history of its common stock equivalent to the expected term of the stock option grants, the expected volatility is derived from the average historical stock volatilities of several unrelated public companies within the Company’s industry that the Company considers to be comparable to its business over a period equivalent to the expected term of the stock option grants. Risk-Free Interest Rate - The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero-coupon U.S. Treasury notes with maturities approximately equal to the option’s expected term. Dividend Rate - The expected dividend is assumed to be zero as the Company has never paid dividends and has no current plans to do so. Fair Value of Common Stock - Given the absence of a public trading market prior to the IPO, the Company’s board of directors considered numerous objective and subjective factors to determine the fair value of its common stock at each grant date, which was $10.75 for the fiscal year 2019. These factors included, but were not limited to (i) independent contemporaneous third-party valuations of common stock; (ii) the lack of marketability of its common stock; and (iii) the likelihood of achieving a liquidity event, such as an initial public offering of the Company, given prevailing market conditions. Subsequent to the IPO, the fair value of common stock is based on the closing price of the Company’s common stock, as reported on The Nasdaq Global Market.

Diluted income (loss) per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include dilutive outstanding employee stock options. For the fiscal years ended August 31, 2021 and August 31, 2020 and 532 thousand outstanding employee stock options, respectively, that were excluded from the calculation of diluted loss per share because their inclusion would have been anti-dilutive.

The primary difference between the effective tax rate and the federal statutory tax rate relates to the recognition of valuation allowance against deferred tax assets, federal tax liabilities offset by employer tip credits, and non-deductible stock-based compensation. The deferred income taxes reflect the tax effects of the temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities are as follows: As of August 31, 2021 2020 (amounts in thousands) Deferred tax assets: NOL carryover $ 7,324 $ 6,472 General business credit 2,496 2,003 Lease liabilities 18,807 16,635 State tax deduction 22 12 Other 1,089 535 Gross deferred tax assets 29,738 25,657 Deferred tax liabilities: Basis difference on fixed assets (4,477 ) (4,593 ) Right-of-use assets (16,880 ) (15,496 ) Gross deferred tax liabilities (21,357 ) (20,089 ) Valuation allowance (8,381 ) (5,568 ) Net deferred tax $ — $ — As of August 31, 2021, the Company has U.S. federal net operating loss (“NOL”) carryover of $28.9 million and federal tax credit carryover of $2.5 million. If not utilized, $25.5 million of the federal NOL can be carried forward indefinitely, and the remainder will begin to expire in the fiscal year ending August 31, 2032. The federal tax credit will begin to expire in the fiscal year ending August 31, 2032. Utilization of the Company’s NOL and federal tax credit carryover may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Sections 382 and 383 of the Internal Revenue Code of 1986, as amended. The Company has not recorded any unrecognized tax benefits as of August 31, 2021. Tax benefits of uncertain tax positions are recognized only if it is more likely than not that the Company will be able to sustain a position taken on an income tax return. The Company has no liability for uncertain positions. Interest and penalties, if any, related to unrecognized tax benefits would be recognized as income tax expense. The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establish valuation allowance when it is more likely than not that all or a portion of a deferred tax asset may not be realized. During the fiscal year ended August 31, 2021, the adverse effects of the COVID-19 pandemic have caused the Company to continue the need for valuation allowances against deferred tax assets. The total amount of the valuation allowances was $8.4 million. On December 27, 2020, Congress passed, and the President signed into law, the Consolidated Appropriations Act, 2021 (the “Act”), which includes certain business tax provisions. The Act did not have a material impact on the Company’s effective tax rate or income tax expense for the fiscal year ended August 31, 2021. On March 11, 2021, Congress passed, and the President signed into law, the American Rescue Plan Act, 2021 (the “ARP”), which includes certain business tax provisions. The ARP did not have a material impact on the Company’s effective tax rate or income tax expense for the fiscal year ended August 31, 2021.

Effects of COVID-19	Effects of COVID-19 The negative effects of the COVID-19 pandemic on the Company’s business have been significant. In March 2020, the World Health Organization declared the novel strain of coronavirus COVID-19 a global pandemic. This contagious virus, which has continued to spread, has adversely affected workforces, customers, economies and financial markets globally. In response to this outbreak, many state and local authorities mandated the temporary closure of non-essential businesses and dine-in restaurant activity or limited indoor dining capacities. COVID-19 and the government measures taken to control it have caused a significant disruption to the Company’s business operation. As of fiscal year-end August 31, 2021, the Company had all of its 32 restaurants operating at 100% indoor dining capacity. In October 2021, the Company opened one new restaurant in San Francisco, California. As of the filing date of this Annual Report on Form 10-K, the Company had all of its 33 restaurants operating at 100% indoor dining capacity. In response to the ongoing COVID-19 pandemic, the Company has prioritized taking steps to protect the health and safety of its employees and customers. The Company has maintained cleaning and sanitizing protocols of its restaurants and has implemented additional training and operational manuals for its restaurant employees, as well as increased handwashing procedures. The Company also provides each restaurant employee with face masks and gloves, and requires each employee to pass a health screening process, which includes a temperature check, before the start of each shift. The reduced capacities at the Company’s restaurants have caused a substantial decline in its sales in the most recently completed fiscal year compared to pre-pandemic levels. In response to the ongoing challenges posed by the COVID-19 pandemic, the Company is focused on maximizing its in-restaurant dining capacity as permitted by the jurisdictions where it operates, continuing to provide a safe environment for its employees and customers, maintaining its operational efficiencies as much as possible and preserving its liquidity. Currently, with the lift of all indoor dining restrictions at all of its restaurants, the Company has experienced a staffing shortage and has provided certain employee retention and new hire bonuses. In line with the Company’s long-term growth strategy, the Company expects to continue to open new restaurants at locations where it believes they have the potential to achieve profitability.
Recent Events Concerning the Company's Financial Position	Recent Events Concerning the Company’s Financial Position On April 10, 2020, the Company and Kura Sushi, Inc. (“Kura Japan”), the majority stockholder of the Company, entered into a Revolving Credit Agreement Under the provisions of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) signed into law on March 27, 2020 and the subsequent extension of the CARES Act, the Company was eligible for a refundable employee retention credit subject to certain criteria. The Company recognized a $10.3 million employee retention credit and a $1.8 million employee retention credit during the fiscal years 2021 and 2020, respectively. For fiscal year 2021, $9.3 million is included in labor and related costs and $1.0 million is included in general and administrative expenses in the statements of operations. For fiscal year 2020, $1.7 million is included in labor and related costs and $0.1 million is included in general and administrative expenses in the statements of operations. The Company has filed for refunds of the employee retention credits and subsequent to August 31, 2021 and as of the date of this Annual Report on Form 10-K, has received $8.0 million in refunds and cannot reasonably estimate when it will receive any or all of the remaining refunds. As of August 31, 2021, the Company is no longer eligible to receive refundable employee retention credits. The Company has received rent concessions from its landlords for certain of its restaurants in the form of rent abatements and rent deferrals which were immaterial for fiscal year 2021. Due to a staffing shortage, the Company provided certain employee retention and new hire bonuses totaling $1.2 Due to the impact of COVID-19, the Company assessed its long-lived assets for potential impairment, which resulted in no impairment charges recorded as of August 31, 2021. The Company also assessed the realizability of its deferred tax assets and, as of August 31, 2021, had a total valuation allowance of $8.4 million. See “Note 10. Income Taxes”.
Basis of Presentation	Basis of Presentation The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company’s fiscal year begins on September 1 and ends on August 31 and references made to “fiscal year 2021”, “fiscal year 2020” and “fiscal year 2019” refer to the Company’s fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods presented. Significant items subject to such estimates include asset retirement obligations, stock-based compensation, the useful lives of assets, the assessment of the recoverability of long-lived assets, and income taxes. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from those estimates and assumptions.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents. The Company maintains its cash and cash equivalents with financial institutions and, at times, the balance may exceed the Federal Deposit Insurance Corporation federally insured limits. The Company has never experienced any losses related to these balances.
Concentration of Significant Suppliers	Concentration of Significant Suppliers The Company relies on third parties for specified food products and supplies. In instances where these parties fail to perform their obligations, the Company may be unable to find alternative suppliers. The Company is subject to supplier concentration risk as JFC International Inc., a subsidiary of Kikkoman Corporation and the Company’s largest supplier, accounted for 58% 27% 28% for fiscal year
Segment Information	Segment Information Management has determined that the Company has one operating segment and therefore one reportable segment. The Company’s chief operating decision maker, its Chief Executive Officer, reviews financial performance and allocates resources. All of the Company’s sales are derived in the United States of America.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist primarily of cash on hand, deposits with banks, money market funds and term deposits. As of August 31, 2021 and August 31, 2020, cash equivalents were $36.1 and $8.8 million, respectively. Due to the short-term maturities and their relatively low interest rates, the carrying value of the money market funds approximates their fair value. Cash and cash equivalents are maintained at financial institutions with strong credit ratings. The Company considers all highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents.
Accounts and Other Receivables	Accounts and Other Receivables Accounts and other receivables consist primarily of receivables from landlords for tenant allowances and credit card receivables. The Company does not extend credit to guests and thus does not have credit risk from guests. Accounts and other receivables balances are stated at the amounts management expects to collect from balances outstanding at fiscal year-end, and no allowance for doubtful accounts is recorded as of August 31, 2021 and August 31, 2020.
Inventories	Inventories Inventories consist of food and beverages and are stated at the lower of cost or net realizable value, with cost determined on an average cost basis.
Property and Equipment	Property and Equipment Property and equipment consists of computer equipment, vehicles, software, furniture and fixtures, leasehold improvements and leased assets. Property and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization on property and equipment is calculated using the straight-line method over the estimated useful lives of the respective assets, ranging from three to 20 years. Leasehold improvements are amortized on a straight-line basis over the shorter of the remaining lease term or estimated life of the improvements. The following table represents the various types of property and equipment and their respective useful lives: Property and Equipment Useful Life Computer equipment 3 – 5 years Vehicles 5 years Software 5 years Furniture and fixtures 10 years Leasehold improvements Shorter of useful life or remaining lease term Lease assets Fixed lease term Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to its estimated fair value.
Liquor Licenses	Liquor Licenses Liquor licenses are deemed to have indefinite useful lives and are subject to annual impairment testing. Liquor licenses are included in deposits and other assets in the accompanying balance sheets.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations (“ARO”) represents the estimated present value of future expenses the Company expects to incur at the end of a lease to restore the location to its original condition. The ARO is recorded as a liability at its estimated present value at inception with an offsetting increase in the carrying amount of the related property and equipment in the accompanying balance sheet. Periodic accretion of the discount of the estimated liability is recorded as interest expense in the accompanying statements of operations. Asset retirement obligations are amortized on a straight-line basis over the shorter of the remaining lease term or estimated life of the leasehold improvements. The Company’s ARO liability is $0.4 million and $0.3 million as of August 31, 2021 and August 31, 2020, respectively and is included in other liabilities in the accompanying balance sheets.
Impairment of Long-lived Assets	Impairment of Long-lived Assets The Company assesses potential impairments of its long-lived assets, which includes property and equipment and operating lease right-of-use assets, in accordance with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360—Property, Plant and Equipment. An impairment test is performed on an annual basis or whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. In determining the recoverability of the asset value, an analysis is performed at the individual restaurant level. Assets are grouped at the individual restaurant level for purposes of the impairment assessment because a restaurant represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of an asset group is measured by a comparison of the carrying amount of an asset group to its estimated undiscounted forecasted restaurant cash flows expected to be generated by the asset group. Factors considered by the Company in estimating future cash flows include but are not limited to: significant underperformance relative to expected historical or projected future operating results; significant changes in the manner of use of the acquired assets; and significant negative industry or economic trends. The estimated undiscounted forecasted cash flows include assumptions made by management regarding certain items such as revenue, food and beverage costs, labor costs, occupancy costs, and other restaurant operating costs and therefore are subject to uncertainty as the Company’s actual results may differ from its estimates. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. The assumptions and estimated undiscounted forecasted cash flows used in the estimate have not changed materially during the year, and
Income Taxes	Income Taxes The provision for income taxes, income taxes payable, and deferred income taxes are determined using the asset and liability method. Deferred income tax assets and liabilities are determined based on temporary differences between the financial carrying amounts and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. The Company establishes a valuation allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income. Income tax expense or benefit is the income tax payable or refundable for the period, plus or minus the change during the period to deferred income tax assets and liabilities. The Company regularly evaluates the likelihood of realizing the benefit for income tax positions it has taken in federal and state filings by considering all facts, circumstances, and information available. For those benefits that the Company believes it is more likely than not will be sustained, it recognizes the largest amount it believes is cumulatively greater than 50% likely to be realized.
Revenue Recognition	Revenue Recognition Revenue from sales is recognized when food and beverages are sold to customers. Sales are presented net of discounts and sales taxes collected from customers.
Sales Taxes	Sales Taxes Sales taxes are imposed by state, county, and city governmental authorities, collected from customers and remitted to the appropriate governmental agency. The Company’s policy is to record the sales taxes collected as a liability on the books and then remove the liability when the sales tax is remitted. There is no impact on the statements of operations as restaurant sales are recorded net of sales tax.
Operating and Finance Leases	Operating and Finance Leases At inception of a contract, the Company assesses whether the contract is a lease based on whether the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Lease classification, measurement, and recognition are determined at lease commencement, which is the date the underlying asset is available for use by the Company. The accounting classification of a lease is based on whether the arrangement is effectively a financed purchase of the underlying asset (finance lease) or not (operating lease). The Company has operating and finance leases for its corporate office, restaurant locations, office equipment, kitchen equipment and automobiles. The leases have remaining lease terms of less than 1 year to 20 years, some of which include options to extend the leases. For leases with renewal periods at the Company’s option, the Company determines the expected lease period based on whether the renewal of any options is reasonably assured at the inception of the lease. Operating leases are accounted for on the balance sheet with the right-of-use (“ROU”) assets and lease liabilities recognized in “Operating lease right-of-use assets,” “Operating lease liabilities - current" and "Operating lease liabilities - noncurrent" on the balance sheet, respectively. Finance leases are accounted for on the balance sheet with ROU assets and lease liabilities recognized in "Property and equipment – net,” “Finance lease - current" and "Finance lease - noncurrent" on the balance sheet, respectively. Lease assets and liabilities are recognized at the lease commencement date. All lease liabilities are measured at the present value of the lease payments not yet paid. To determine the present value of lease payments not yet paid, the Company estimates incremental borrowing rates corresponding to the maturities of the leases. As the Company has no outstanding debt, it estimates this rate based on prevailing financial market conditions, comparable company and credit analysis, and management judgment. ROU assets, for both operating and finance leases, are initially measured based on the lease liability, adjusted for initial direct costs, prepaid or deferred rent, and lease incentives. The operating lease ROU assets are subsequently measured at the carrying amount of the lease liability adjusted for initial direct costs, prepaid or accrued lease payments, and lease incentives. Depreciation of the finance lease ROU assets are subsequently calculated using the straight-line method over the shorter of the estimated useful lives or the expected lease terms and recorded in "Depreciation and amortization expense" on the statement of operations. The Company accounts for lease and non-lease components as a single component for its entire population of operating lease assets. The Company recognizes expense for these leases on a straight-line basis over the lease term. In addition to the fixed minimum payments required under the lease arrangements, certain leases require variable lease payments, such as common area maintenance, insurance and real estate taxes, which are recognized when the associated activity occurs. Additionally, contingent rental payments based on sales thresholds for certain of its restaurants are accrued based on estimated sales.
Other Costs	Other Costs Other costs in restaurant operating costs in the accompanying statements of operations include utilities, repairs and maintenance, credit card fees, royalty payments, stock-based compensation for restaurant-level employees, and other restaurant-level expenses. The Company incurred $10.4 million, $6.7 million and $7.1 million in other costs for the fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and are included in other costs in the accompanying statements of operations. The Company incurred $0.6 million, $0.3 million and $0.4 million in advertising expenses for the fiscal years ended August 31, 2021, August 31, 2020 and August 31, 2019, respectively.
Fair Value Measurements	Fair Value Measurements The Company defines fair value as the exchange price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value measurement accounting guidance creates a fair value hierarchy to prioritize the inputs used to measure fair value into three categories. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement, where Level 1 is the highest and Level 3 is the lowest. The three levels are defined as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets. Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 – Observable inputs other than Level 1 prices, such as unadjusted quoted prices for similar assets or liabilities in active markets, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on the Company’s own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation. The Company’s financial statements include cash and cash equivalents, accounts and other receivables, accounts payable, accrued expenses and other current liabilities, and salaries and wages payable for which the carrying amounts approximate fair value due to their short-term maturity. The fair value of payments due to or from Kura Japan is not determinable due to its related-party nature.
Stock-based Compensation	Stock-based Compensation Stock-based compensation consists of stock options issued to employees and non-employees. The Company measures and recognizes stock-based compensation for the estimated fair value of stock options based on the grant date fair value of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model and is impacted by the fair value of the Company’s common stock, as well as changes in assumptions regarding certain subjective variables. These variables include, but are not limited to, the expected common stock price volatility over the term of the stock option awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. For stock options that are based on a service requirement, the cost is recognized on a straight-line basis over the requisite service period, which is typically the vesting period. Stock options granted in fiscal year 2021 have vesting periods ranging from 12 months to 48 months. Stock options granted in fiscal year 2020 have vesting periods ranging from 9 months to 46 months. The majority of stock options granted in fiscal 2019 have a vesting period of approximately 45 months.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) is the same as net income (loss) for all periods presented. Therefore, a separate statement of comprehensive income (loss) is not included in the accompanying financial statements.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Earnings (loss) per share is calculated by dividing net income (loss) by the weighted average shares outstanding during the period, without consideration of common stock equivalents. Diluted earnings per share assumes the conversion, exercise or issuance of all potential dilutive common stock equivalents outstanding for the period. For the purposes of this calculation, options are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive. Diluted earnings per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements On September 1, 2019, the Company adopted ASU 2016-02, “Leases (Topic 842)” (“Topic 842”), along with related clarifications and improvements. As a result of the adoption of Topic 842, the accompanying balance sheets and fiscal years 2021 and 2020 statement of operations and statement of cash flows reflect the adoption; however, the fiscal year 2019 statement of operations and statement of cash flows are presented on the basis of ASC Topic 840: “Leases.” The adoption of Topic 842 had an immaterial impact on the statement of operations and statement of cash flows. Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which is intended to simplify various aspects related to accounting for income taxes. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. ASU 2019-12 is effective for the Company beginning in fiscal year 2022. The Company is currently in the process of evaluating the effects of this pronouncement on its financial statements.
