What Well Link does

Well Link Co., Ltd. (ウェルリンク株式会社) is a privately held Japanese mental health and workplace wellness provider founded in March 2000 as a spin-off of the health software division of Exit Co., Ltd. Headquartered in Meguro, Tokyo, with a Kansai sales office in Osaka opened in October 2015, the company serves Japanese enterprises and public institutions with stress check administration, counseling, harassment countermeasures, training and consulting, caregiving work-balance support, and health management certification advisory. Its primary customers include approximately 1,300 corporate clients across industries such as insurance (Asahi Seimei), construction (Ando Hazama), food and beverage (Itochu Shokuhin), IT (Intec), entertainment (gumi), and education (Toyo University), alongside multiple government bodies including the National Police Agency and Gunma Prefectural Government.

The company's core technology is the Self® comprehensive stress check platform, originally launched in June 2002 based on a statistical analysis method filed as a Japanese business model patent (Application EX0101) in October 2000. Self® combines individual stress assessment — separating work-related and private-life stress factors — with organizational group analysis across department, occupation, and employment-form cuts, supporting compliance under Japan's Industrial Safety and Health Act stress check mandate (Article 66-10). The platform has accumulated over 3.5 million cumulative users since launch. Supporting modules include on-demand occupational physician interviews, multi-format counseling (phone, email, in-person, CISM emergency response, return-to-work support), harassment countermeasures (training, hotlines, perpetrator/victim programs), and content delivery through the Wellメディア platform. In March 2024, Well Link launched Nadeshiko Link®, a women's career advancement solution, signaling platform extension beyond traditional mental health.

Well Link generates revenue primarily through annual enterprise subscription contracts covering stress check administration, group analysis, counseling access, and training, supplemented by project-based professional services for consulting and certification advisory work. Pricing is quote-based and not publicly disclosed. The company operates with 40 full-time staff and 342 contracted part-time counselors, instructors, and physicians. It has earned Privacy Mark certification for the healthcare sector (JIS Q 15001) in March 2006, ISMS certification (ISO/IEC 27001) under registration I430, and MHLW Mental Health Support Center registration in February 2011, and has received the Health Management Excellence Organization designation for seven consecutive years including Bright 500 selection in 2026.
