During our 26th fiscal year (from January 1, 2025 to December 31, 2025), the Japanese economy continued on a moderate recovery trend, supported by personal consumption reflecting improved employment and income conditions, as well as further expansion in inbound tourism demand. However, factors such as rising import prices driven by the depreciation of the yen and unstable international conditions have continued to create uncertainty for both domestic and international economies and markets.

Under these circumstances, we continued to strengthen our structure as a pure holding company following the transition in July 2023 and focused on improving group management efficiency and expanding our revenue base. Through the reorganization of certain of our subsidiaries effective January 1, 2025 (integration into MEDIROM Wellness Co.), we consolidated the management structure of the relaxation salon segment and promoted the optimal allocation of management resources.

With respect to the relaxation salon operation segment, primarily through MEDIROM Wellness Co., we continued to work on shortening the lead time before newly hired staff are deployed to salons through improvements in our training and education programs, and strengthening recruitment of contract-based therapists, in response to the intensification of competition for talent in the job market. We also promoted the adoption of our in-house payment system “Re.Ra.Ku PAY” to improve customer convenience and enhance the efficiency of salon operations through cashless payments. Furthermore, in commemoration of our 25th anniversary, we held a special customer appreciation event and offered “Special Value Tickets” to strengthen customer relationships and drive customer acquisition. In terms of new salon openings, we continued working to close certain existing salons and open new salons with caution, resulting in a total of 292 salons in the group as of December 31, 2025. Additionally, sales of salons to investors also grew steadily, with MEDIROM Wellness Co. selling 58 salons (including resales and brokering sales between investors), respectively, during the fiscal year.

Furthermore, in August 2025, in collaboration with Hakuhodo Inc., we announced our participation in the “World” protocol promoted by Tools for Humanity (“TFH”), co-founded and chaired by Sam Altman, co-founder of OpenAI. We commenced entry into a new business area contributing to the development of a “proof of humanity” infrastructure for the AI era, through the installation and operation of the World ID authentication device “Orb” at our “Re.Ra.Ku” salons. Subsequently, effective February 2, 2026, this business transitioned to a direct contract with TFH.

With respect to the healthtech segment (which mainly consists of the following operations: government-sponsored specific health guidance program and our MOTHER Bracelet^® business), primarily through MEDIROM MOTHER Labs Inc., we

8

continued to promote our health guidance program utilizing our internally-developed on-demand health monitoring smartphone application, Lav^®, and steadily expanded our client base, which mainly consists of health insurance providers, and as of December 31, 2025, we had entered into contracts with 102 health insurance providers. We also worked to promote MOTHER Bracelet®, the world's self-charging smart tracker, and in light of the severe heat conditions experienced in recent summers, we enhanced our heat illness prevention solution utilizing the device's function to detect changes in physical condition from vital data. As a result, adoption expanded across construction sites with a large proportion of outdoor workers, care facilities and local governments with high monitoring needs, contributing to the resolution of social challenges and advancing the establishment of a business-to-business (BtoB) revenue model.

With respect to the rehabilitation center operation segment, MEDIROM Rehab Solutions Inc. continued to work toward establishing a solid revenue base for the rehabilitation center operation business acquired in the previous fiscal year.

With respect to financing activities, with the aim of flexible financing and strengthening of our financial base, we issued the 3rd series of Unsecured Convertible-Type Corporate Bonds with Stock Acquisition Rights on November 27, 2025 raising a total of JPY 400 million. Through these measures, we have worked to secure a stable financial foundation for future growth investments.

Financial Results Under Japanese GAAP

Note: The following discussion is based upon our statutory non-consolidated financial results prepared in accordance with Japanese generally accepted accounting principles (“GAAP”) which have not been reviewed or audited by an independent auditor. As such, these results may differ in material respects from the financial results and audited consolidated financial statements prepared in accordance with U.S. GAAP that will be reported at a later date and included in our Annual Report on Form 20-F to be filed with the U.S. Securities and Exchange Commission (the “SEC”) and available at www.sec.gov. U.S. GAAP results for the year ended December 31, 2025 remain subject to the completion of management’s reviews and reconciliations and/or adjustments under U.S. GAAP, the Company’s other financial closing procedures, and the audit by the Company’s independent auditor in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”). Furthermore, in addition to reflecting the consolidation of entities that is not reflected in these non-consolidated Japanese GAAP financial results, these U.S. GAAP financial statements and results may differ from our Japanese GAAP results due to the completion of the Company’s financial closing procedures, the audit under the standards of the PCAOB, and other developments that may arise during the audit process under the standards of the PCAOB. Accordingly, you should not place undue reliance on this information. See “Important Notice Regarding Japanese GAAP Financial Information” below.

The discussion of financial results below is presented to our shareholders and holders of our American Depositary Shares (“ADSs”) solely for purposes of compliance with requirements under the Japanese Companies Act in connection with our 26^th Ordinary General Meeting of Shareholders. For your convenience, information presented in Japanese yen has been translated into U.S. dollars based upon the conversion rate of $1.00 = JPY 156.80, as reported by the Federal Reserve Bank on December 31, 2025.

For the year ended December 31, 2025, the Company recorded (i) net revenues of 604,533 thousand yen (US$3,855 thousand), while the Company recorded net revenue of 778,035 thousand yen (US$4,949 thousand) for the year ended December 31, 2024, (ii) operating income of 61,980 thousand yen (US$395 thousand), while the Company recorded operating income of 116,562 thousand yen (US$740 thousand) for the year ended December 31, 2024, and (iii) ordinary income of 39,893 thousand yen (US$254 thousand), while the Company recorded ordinary income of 115,609 thousand yen (US$734 thousand) for the year ended December 31, 2024, on a non-consolidated basis, under Japanese GAAP. These standalone figures reflect the impact, among other factors, of optimizing our commissioned fees charged to our subsidiaries, following the revision of the store sales fee calculation standards to better manage the group’s overall profit and loss.

Our audited consolidated financial statements for the year ended December 31, 2025 prepared in accordance with U.S. GAAP will be reported at a later date and included in our Annual Report on Form 20-F to be filed with the SEC.

Important Notice Regarding Japanese GAAP Financial Information

The financial results for the year ended December 31, 2025 presented in this business report and the accompanying Japanese GAAP financial statements are prepared solely in accordance with Japanese GAAP on a non-consolidated basis, have not been reviewed or audited under Japanese generally accepted auditing standards (“GAAS”), the standards of the PCAOB or

9

U.S. GAAS, and do not present all information necessary for an understanding of the Company’s results of operations for the year ended December 31, 2025. Our U.S. GAAP results for the year ended December 31, 2025 remain subject to the completion of management’s reviews and reconciliations and/or adjustments under U.S. GAAP, the Company’s other financial closing procedures, and the audit by the Company’s independent auditor in accordance with the standards of the PCAOB, and may differ from the Japanese GAAP results for this period due to the completion of the Company’s financial closing procedures, the audit under the standards of the PCAOB, and other developments that may arise during the audit process.

The Company expects that its audited consolidated U.S. GAAP results for the year ended December 31, 2025, in addition to reflecting the consolidation of entities that is not reflected in the non-consolidated Japanese GAAP financial results, may differ from the Japanese GAAP results contained in this business report and the accompanying Japanese GAAP financial statements in the following line items, among others: (1) increase/decrease in amortization expenses recognized from the difference in the accounting treatment of salon purchases; (2) recognition of impairment losses on our long-lived salon assets, goodwill and other intangible assets; (3) increase/decrease in allowance or provisional expenses; and (4) the accounting treatment of the Company’s sales of shares of one of its subsidiaries.

The Japanese GAAP financial results included in this business report have been prepared by and are the responsibility of the Company’s management. In addition, the Japanese GAAP financial results have not been reviewed or audited by an independent auditor and therefore do not reflect any potential changes that may have resulted had such financial results been audited under Japanese GAAS. The Company’s independent U.S. auditor has not audited, reviewed, compiled, or performed any procedures with respect to the Japanese GAAP financial results presented in this business report or the accompanying Japanese GAAP financial statements under either the standards of the PCAOB or U.S. GAAS. Accordingly, the Company’s independent U.S. auditor does not express an opinion or any other form of assurance with respect thereto.

The Company intends to file its Annual Report on Form 20-F containing the audited financial statements for the year ended December 31, 2025 prepared in accordance with U.S. GAAP by the filing deadline prescribed by the SEC, and such financial information for 2025 contained in the Annual Report, including the Company’s audited financial statements prepared in accordance with U.S. GAAP, may differ from the Japanese GAAP financial information disclosed in this business report and the accompanying Japanese GAAP financial statements. As such, this Japanese GAAP financial information should not be viewed as a substitute for the Company’s audited annual financial statements prepared in accordance with U.S. GAAP and is not necessarily indicative of any future period. Accordingly, you should not place undue reliance on this Japanese GAAP information.

There are no matters to be stated.

On January 1, 2025, an absorption-type merger was conducted with Wing Inc. as the surviving company and Medirom Human Resources Inc. as the extinguished company, along with an absorption-type company split in which Wing Inc. was the succeeding company and JOYHANDS WELLNESS Inc. was the splitting company, transferring JOYHANDS WELLNESS Inc.'s relaxation salon operation business to Wing Inc. On the same date, Wing Inc. changed its company name to MEDIROM Wellness Co.

With the aim of flexible financing and strengthening of our financial base, on November 27, 2025, we issued the 3rd series of Unsecured Convertible-Type Corporate Bonds with Stock Acquisition Rights, raising JPY 400 million.

10

While we continue to face a challenging business environment due to rising prices driven by the depreciation of the yen and increasing labor costs, we are working to build a robust internal structure that can withstand these conditions and aim to secure stable earnings.

In respect of the relaxation salon segment, we will continue our efforts to optimize personnel allocation in response to busy and off-peak periods at salons, shorten the lead time before newly hired staff are deployed to salons through improvements in our training and education programs, strengthen recruitment of contract-based therapists, and work to strengthen our revenue base through accelerating cashless adoption by promoting “Re.Ra.Ku PAY” and improving customer repeat ratios. We will continue to strive to improve customer satisfaction and increase sales, improve the efficiency of directly managed and franchised salon operations, and expand salon sales to investors.

In connection with our participation in the “World” protocol, we will collaborate with TFH to promote the installation and operation of “Orb” devices at our “Re.Ra.Ku” salons, contribute to the domestic expansion of World ID, and aim to establish a new revenue model.

In connection with the healthtech segment, we will strive to further expand the number of health insurance providers under contract with us in our health guidance program utilizing the Lav® application, while working to improve profitability. Additionally, with regard to our heat illness prevention solution and “REMONY”, a remote monitoring and centralized management system using MOTHER Bracelet®, we will promote expanded adoption primarily in the construction, care facility, and local government sectors, and aim to further establish a business-to-business (BtoB) revenue model.

With respect to the rehabilitation center operation segment, MEDIROM Rehab Solutions Inc. will steadily advance the monetization of existing locations while also working to create business synergies in the wellness domain.

Additionally, our Company views acquiring business opportunities through M&A as a strategic priority for achieving sustainable growth and maximizing corporate value. Moving forward, we intend to continue to strengthen our organizational structure, enhance risk management, expedite and optimize the integration process of acquired businesses, and proactively implement measures to ensure these initiatives contribute reliably to our performance.

The Company's Corporate Auditors shall receive notifications on the operation of the whistle-blowing system once a quarter. If they deem it necessary, the Corporate Auditors may have relevant personnel immediately report on the system's operation.

The Directors of the Company shall establish the standard rules of the Company stipulating that those who have made the report described in the preceding item shall not be treated disadvantageously because of such information and shall operate the rules appropriately after making them known to each subsidiary of the Company.

If the Company's Corporate Auditors request advance payment or redemption procedures of expenses incurred in the performance of their duties, the Company's Directors shall promptly pay such fees, except in cases where such payment is deemed unnecessary for the performance of the Corporate Auditors' duties, under the internal rules established through consultation with the Company's Corporate Auditors.

The Company's Corporate Auditors shall hold meetings to exchange opinions with the representative directors and outside directors of the Company regularly. Besides, the Directors of the Company shall establish a system to ensure that the audits by the Company's Corporate Auditors are conducted effectively, such as by ensuring that the Company's Corporate Auditors have the opportunity to attend meetings of each subsidiary of the Company at the request of the Company's Corporate Auditors.

(2)Overview of the operation of the system to ensure the appropriateness of operations.

In 2020, our common shares represented by ADSs became listed on the Nasdaq Stock Market in the United States, and as a large company under the Companies Act, we have worked to establish a so-called “system of internal control over financial reporting” to ensure appropriate business operations. Specifically, we worked to document business processes and improve deficiencies in internal controls to comply with the Sarbanes-Oxley Act of the United States, prepare for the replacement and introduction of business systems, and reinforce accounting personnel. At the same time, we promoted the acceleration of the account closing process and the strengthening of the review process by allocating operations more efficiently.

In addition, the Board of Directors met 13 times, these being the main meetings to monitor and supervise the appropriate operation of the business described in (1) above. In addition to ensuring the legality of the execution of duties by directors, Mr. Ogawa and Mr. Nojima, outside directors who have no conflicts of interest with the Company, attended 12 meetings and all meetings of the Board of Directors, respectively. The Board of Corporate Auditors met 12 times.

The members of the Board of Corporate Auditors conduct audits based on the audit plans established by the Board of Corporate Auditors, and exchange opinions with our representative directors, other directors, the Internal Audit Office, and the accounting auditor.

In order to confirm the appropriateness of the operational status of our business, we established the Internal Audit Office and appointed dedicated personnel.

(3)Basic Policy on Control of Kabushiki Kaisha

As a Japanese company with ADSs listed on overseas markets, we respect the free trading of our ADSs in the market, and according to our amended and restated articles of incorporation and under the Companies Act, the final decision on whether to accept a proposal for a purchase of the Company's shares that would result in a change of control should be left to the shareholders.

The Company has issued one (1) Class A share with Kouji Eguchi, the founder, and representative director, as the holder. The Class A share is so-called “golden share” with the same rights as common shares in terms of dividends and receipt of residual assets and has the right to consent to critical corporate decisions such as reorganization and disposal of substantial assets and issuance of new shares.

The Company's Board of Directors, including outside directors, shall determine whether a party conducting a tender offer for a significant purchase of the Company's shares is a party that contributes to the enhancement of the Company's corporate value and, in turn, the common interests of its shareholders. The Board of Directors, including the outside directors, will take appropriate measures to consider the laws of Japan and the United States, where the Company's ADSs are listed.

Under the Japanese Companies Act and our Articles of Incorporation, our shareholders are entitled to have information and time to consider whether or not to accept a tender offer for a change of control and protect the Company's corporate value and the shareholders' common interests. The Company believes that it is essential to ensure that shareholders have such information and time.

(4)Company policy in regard to the decisions related to distribution of dividends etc.

The Company considers the distribution of earnings to our shareholders as an essential management policy. Our basic approach is to strive to continuously provide stable returns to our shareholders while securing the necessary internal reserves to respond to future growth and changes in the business environment. However, currently we plan to actively invest in our business to achieve further growth in the future, and we do not expect to pay any dividends on our common shares for the foreseeable future.

(Significant accounting policies)

Securities without market price are stated at the moving average cost.

The depreciation methods and applicable usage periods are as follows:Property and equipment: Straight-line method, 7-15 years

Vehicles: Declining balance method, 6 years

Tools, furniture and fixtures: Declining balance method, 3-10 years

Straight-line method is adopted. Software for company use is amortized over the useful life (5 years depending on each software).

3.Basis to recognize allowances

The Company estimates uncollectible amounts of its receivables by multiplying historical bad debt ratio of receivables with accounts receivable amount for those without specific sign of default, and by individually estimating collectability of each specific receivable such as those with sign of default.

Revenues are recognized when control of the promised goods or services are transferred to the customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.

The Company determines revenue recognition through the following steps:

Step 1: identification of the contract with a customer;

29

[This is an English translation of the original issued in Japanese]

Step 2: identification of the performance obligations in the contract;

Step 3: determination of the transaction price;

Step 4: allocation of the transaction price to the performance obligations in the contract; and

Step 5: recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company’s primary revenue sources consist of the consulting fees determined based on the number of sales of salon transactions that are closed by its subsidiaries and the royalty income related to its trademarks. The Company is entitled to a performance bonus when a sale of salon transaction is closed as the Company provides consulting services to find buyers and close transactions, and the Company recognizes the revenue upon a salon sale transaction is closed as a performance obligation is considered to be satisfied. The Company calculates the amount of royalty income based on the number of salons and the certain fees per salon, and the Company allows the subsidiaries to use the Company’s trademarks over the contract period and performance obligation is deemed to be satisfied as the time passes. As such, the Company recognizes royalty income over the contract period. The considerations for the above revenue transactions do not include significant financial elements.

(Notes related to accounting estimates)

(Evaluation of investments, loans receivable, and accounts receivable from our subsidiaries)

​

2．Information related to accounting estimates over the identified items

The judgments on necessity/unnecessity to impair the investments on common shares of subsidiaries without market prices is done by comparing the purchase price and practical price, and if the practical price has dramatically decreased, the Company impairs the investment amounts except the case that collectability of the invested amounts is sufficiently supported by enough evidences. The Company uses future plans and so on for the judgment of such collectability.

The receivables from our subsidiaries are evaluated by each entity for the estimated uncollectible amounts, and such estimated uncollectible amounts are recognized as allowance for doubtful accounts. Such uncollectible amounts are estimated based on the financial position of each subsidiary considering general ability to pay by each subsidiary.

If the financial positions or operating performance of the subsidiaries are worsened in the following fiscal year, there is a risk that the Company needs to recognize losses from impairment of the investments on subsidiaries and/or allowance for doubtful accounts, which could impact our financial positions and/or operating performance.

The fair values of financial instruments include reasonably estimated amounts in case there is no market value. Such a value calculation reflects volatile factors, and so subject to change of the value due to adopting different assumptions.

The disclosed amounts on the Balance Sheet, fair values, the differences as of December 31, 2025 are as presented in the following table. The table excludes financial instruments, the fair value of which is deemed impossible to determine. (Please see Note 2 below.) Furthermore, cash is omitted from the table and bank balances, accounts receivable-trade, accounts receivable-other, accounts payable-other, short-term loans receivable, accounts payable-trade, accounts payable-other, and short-term loans payable are omitted from the table since they can be settled within a short period and so their fair values approximate their book values.

※5　Convertible bond due within 1 year is included.

​

(Note 1)  Items related to calculation methodologies of financial instruments and securities or derivative transactions

Since the estimated uncollectible amounts are calculated based on the expected collectible amounts, etc., the fair values of them are approximate with the amount disclosed on the Balance Sheet less the latest estimated bad debt as of fiscal year end. Hence, the Company regards the amount as the fair value of this account.

The fair value of the Long-term borrowings, Convertible bonds with share acquisition rights, and Long-term accounts payable-other are calculated under the method that the sum of principals and interest payable is discounted by the interest rates assumed to be applicable provided the Company newly entered into the loan agreements with the same terms and conditions.
