Company profile
researched Aug 2026株式会社メンタルヘルステクノロジーズ (MentalHealth Technologies Co, Ltd.) is a Tokyo-based healthcare company headquartered at 3-16-11 Akasaka, Minato-ku, Tokyo. It operates four reported business segments: mental health solutions, medical work shift, medical career support, and digital marketing. Its core offering is "産業医クラウド" (Sangyoi Cloud / occupational physician cloud), which packages service delivery by occupational physicians, in-house occupational health nurses and DX support staff together with the cloud-based mental care software suite "ELPIS". ELPIS supports stress checks, online interviews and counselling, and cloud management of employee health data. The parent company itself handles group management, marketing support and ELPIS development, while operating subsidiaries deliver services.
The group describes itself as a BPaaS provider specialised in the medical and healthcare field. Subsidiaries include 株式会社Avenir (occupational physician cloud for corporates and job-change support for medical professionals; wholly owned), 株式会社ヘルスケアDX (management, operations and patient-acquisition support for medical institutions), 株式会社明照会労働衛生コンサルタント事務所 (Nagoya-based occupational health services for the Tokai region), 株式会社タスクフォース (staffing services for medical institutions, mainly nursing assistants), 株式会社みらい産業医事務所 (Fukuoka-based occupational health services for Kyushu), and インクルード株式会社 (operator of the Neuro Rework return-to-work and re-employment support service). Additional group services cover employment transition support/independence training for people with depression or mental health difficulties, mental clinic operation support, and digital marketing including medical-society services and website production.
The company frames its market opportunity around rising rates of mental illness in Japan (from 2.58 million patients in 2002 to over 6 million in 2020), projected labour shortages of 6.44 million people by 2030, and demographic ageing. It states a mission of "幸せをリデザインする" and a vision of "ウェルビーイングのスタンダードを創る" (creating a standard for well-being).
Founding story
The company was founded in March 2011 in Chiyoda-ku, Tokyo as 株式会社Miew, an IT solutions business (now the digital marketing segment), by 刀禰真之介, who became representative director and president. Prior to founding the company he worked at Deloitte Tohmatsu Consulting (now Abeam Consulting), UFJ Tsubasa Securities (now Mitsubishi UFJ Morgan Stanley Securities) and Environmental Energy Investment. The founding-era slogan was "人が家で永眠可能な社会の実現", later reframed into the mission "幸せをリデザインする".
Business model
The company sells packaged occupational health and mental health services to corporate employers, combining human service delivery (occupational physicians, occupational health nurses, DX support staff) with subscription cloud software (ELPIS series) under the "産業医クラウド" brand. Adjacent revenue lines come from placement and staffing services for medical professionals and nursing assistants, operational and patient-acquisition support for medical institutions and mental clinics, employment-transition/rework support programmes, and digital marketing work including medical-society electronic publishing systems and web marketing built on a physician database.
Segment revenue is reported across mental health solutions, medical work shift, medical career support and digital marketing. Mental health solution revenue derives from packaged occupational physician services plus cloud service subscriptions; medical career support derives from physician recruitment/placement; digital marketing derives from system maintenance, application provision, site construction and outsourced web marketing.
Traction
As of the end of June 2026 the company reported 1,659 consolidated employees (excluding directors and part-time staff, but including employees concurrently serving as officers) and capital of 559,269 thousand yen. Its IPO market capitalisation at the initial trading price was 8,462 million yen. The group comprises six wholly owned subsidiaries alongside the parent.
Latest developments
In March 2026 the company acquired all shares of インクルード株式会社, operator of the Neuro Rework return-to-work and re-employment support service, making it a wholly owned consolidated subsidiary. During 2026 the company also publicised media coverage of its CEO and of occupational health nurses at subsidiary Avenir, and it maintains open solicitations for acquisitions of, and investments in, mental health businesses, medical staffing services and clinics.

Market position
The company positions itself as a leading provider of well-being services and a BPaaS provider specialised in the medical and healthcare domain, describing its offering as an all-in-one, non-stop service covering mental health from all angles and focused on "problem-solving operation" rather than minimum legal compliance. It cites the Japanese mental health care market as exceeding 500 billion yen and has stated a target of more than doubling annually.
The company states that it differentiates by combining human occupational health delivery with proprietary cloud software in a single package, offering all-in-one coverage of mental health rather than point solutions, and by focusing on active problem-solving rather than minimum statutory compliance. Its medical career support arm can offer physicians occupational physician roles in addition to conventional clinical placements because the mental health solution business sits inside the same group.
Technology
The ELPIS series is a cloud-based mental care and health management software suite developed in-house by the parent company. Functions cited include stress checks, online interviews and counselling, and cloud-based management of employee physical and mental health data. Digital marketing work includes the medical-society electronic book service "KaLib" developed with 株式会社杏林舍 and system maintenance and operation of the Japan Medical Association's "日医Lib", plus applications and sites for medical societies and a physician database used for marketing support.
Go-to-market
The company sells directly to corporate employers under the "産業医クラウド" brand, supported by television advertising featuring actress 安達祐実, published survey research on workplace mental health and physician opinion, seminars, and books authored by the CEO. Regional coverage is extended through acquired local occupational health practices, and the company publicly solicits acquisitions of and investments in mental health businesses, medical staffing firms and clinics.
Corporate employers, particularly large companies, seeking occupational health and mental health programmes; medical institutions requiring management, operations, patient-acquisition and staffing support; physicians and medical professionals seeking career moves; medical societies and general companies buying digital marketing services; and individuals returning to work after mental health difficulties.
Geography
Headquartered in Minato-ku, Tokyo, with nationwide service coverage in Japan. Regional occupational health delivery is provided from Nagoya for the Tokai area (明照会労働衛生コンサルタント事務所) and from Fukuoka for the Kyushu area (みらい産業医事務所). The company has said it would consider expansion into overseas markets such as China and Singapore after strengthening its domestic base.
