Business

MRSO, Inc. is a HealthTech company that promotes the digitalization of preventive medicine, centered on its health checkup and medical examination reservation site "MRSO.jp". Based on its platform, which lists the largest number of medical institutions in Japan (1,906 as of the end of December 2025), the company offers reservation and advertising services for individuals, as well as DX services for medical institutions, corporations, and government entities. The company serves a wide range of customers, from individuals to corporations and government, through partnerships with major life insurance companies such as Sumitomo Life, Meiji Yasuda Life, and Fukoku Life to provide reservation functions, as well as corporate reservations (with a corporate user base of approximately 700,000 people), which began in earnest in April 2025. The company listed on the Tokyo Stock Exchange Growth Market in December 2023.

Business Model

The core reservation revenue is a performance-based model in which medical institutions pay a service fee based on the examination amount when examinees make reservations and receive checkups via MRSO.jp. Advertising revenue secures stable income through increased exposure for medical institutions and support for corporate promotions. DX revenue is recurring (stock-type) revenue generated by providing web reservation systems for medical institutions, corporations, and government entities. In FY2025 (ending December 2025), the revenue composition was 56.5% reservation, 28.2% advertising, and 15.2% DX.

Company Strengths

The number of medical facilities listed on MRSO.jp reached 1,906 as of the end of December 2025 (up 229 from the previous period). Covering everything from national and public hospitals to major group hospitals and clinics, the service has been recognized as No. 1 among the top 3 individual health checkup reservation sites in a survey conducted by Do House Inc.

The company provides reservation functionality through business alliances with major life insurance companies including Sumitomo Life, Meiji Yasuda Life, Sony Life, Fukoku Mutual Life, Asahi Mutual Life, and Hanasaku Life. For corporate reservations launched in April 2025, the corporate base (the number of health checkup targets at contracted organizations) has already expanded to approximately 700,000 people.

In 2016, the company obtained and renewed ISMS (ISO27001) and QMS (ISO9001) certifications, and in 2017 also obtained the Privacy Mark (P Mark). As a platform handling sensitive medical and health information, the company has established an institutional foundation of trust.

ENVALITH's Perspective

For Q1 of FY2026 (ending December 2026), operating loss was ¥(10) million (vs. ¥(12) million in the same period last year), and quarterly net loss was ¥(5) million (vs. ¥(10) million in the same period last year), confirming a narrowing of losses. Revenue also showed modest growth, up 3.6% year-on-year to ¥291 million. However, the full-year forecast calls for revenue of ¥1,262 million (+17.1%) and an operating loss of ¥(76) million, with Q1 progress against the full-year revenue target at only about 23%. Whether corporate reservations gain full momentum in the second half will be key to achieving the full-year targets.

In Q1, the company disclosed that corporate reservation transaction volume, a leading indicator of revenue, increased significantly year-on-year, although specific figures were not disclosed. Given the time lag between transaction volume and revenue recognition (performance-based fees are recognized after health checkups are conducted), the increase in Q1 transaction volume is expected to be reflected in revenue and profit mainly from Q2 onward. As an external factor, shifts in US trade policy and geopolitical risks are exerting downward pressure on corporate capital expenditure sentiment, making it necessary to continue closely monitoring trends in corporate health checkup demand.

In Q1, selling, general and administrative expenses continued to increase, reaching ¥235 million (vs. ¥231 million in the same period last year), a structure that continues to exceed gross profit of ¥225 million. For FY2026 (ending December 2026), the company plans to actively pursue strategic investments such as personnel expansion, and achieving the full-year revenue forecast of +17.1% will require a sharp acceleration in the second half. Risks remain regarding the vulnerability of the earnings structure, including the potential for the small-scale organization of about 25 employees to become a bottleneck in hiring and training, as well as the risk of dependence on SEO for individual reservations.

Growth Strategy

Transforming the earnings structure through full-scale entry into the corporate reservation market (approx. ¥600 billion) and expansion of DX services

Centered on health checkup arrangement services for corporations and health insurance societies, the company is expanding corporate reservation transaction volume by leveraging its base of approximately 700,000 corporate health checkup recipients. In Q1 of FY2026 (ending December 2026), transaction volume achieved a significant year-on-year increase, and the company aims to accelerate penetration into the approximately ¥600 billion corporate reservation market.

Through ongoing sales activities, the company is expanding the number of listed medical institutions, strengthening the foundation for reservation revenue and advertising revenue. As of the end of December 2025, the number reached 1,906 facilities, and increasing the number of facilities directly contributes to enhancing the platform's ability to attract users.

Centered on the MRS (Web Reservation System for Medical Institutions) for medical institutions, government bodies, and corporations, the company is deploying an integrated DX service covering everything from health checkup reservations to health data management. The company is also expanding its scope of provision to government entities, primarily municipalities, aiming for a steady accumulation of DX-related revenue.

Toward FY2026 (ending December 2026), the company is accelerating strategic investment including workforce expansion. Selling, general and administrative expenses are on an increasing trend, and the company's policy is to prioritize building a medium- to long-term earnings foundation while accepting a short-term expansion of losses. Ample cash on hand (¥1,637 million) underpins the capacity for investment.
