Medical Corporation Koujinkai

What Medical Corporation Koujinkai does

Medical Corporation Koujinkai (医療法人社団光仁会) is a private Japanese medical corporation founded in 1980 and headquartered in Hiroshima City, operating an integrated medical and long-term care network across six wholly-owned facilities. The group centers on Kajikawa Hospital, an 88-bed community hospital in Nishi-ku offering internal medicine, surgery, urology, orthopedics, cardiovascular care, and rehabilitation, with a mix of community integrated care beds and medical care beds. Adjacent to the hospital, Phoenix Clinic operates a 34-console artificial dialysis center specialized in long-duration (5–6 hour) hemodialysis, Online HDF, and intermittent HDF, augmented by a kidney rehabilitation program where physical therapists conduct in-bed exercise therapy during dialysis sessions.

The long-term care arm includes Ashitaba Visiting Nursing Station (home nursing and rehabilitation, established 1995), Rinden care management office, Sumire day-care/day-rehabilitation, and Benimansaku no Sato, a 100-bed home-reinforcement-type elderly care facility in Hatsukaichi City that also operates 40 day-care slots and uses Cyberdyne's HAL lumbar-support robot for caregiver injury prevention. Revenue is generated across three streams — medical services (hospital and clinic), long-term care insurance services (home nursing, day care, short-stay, care management), and the elderly care facility — all reimbursed under Japan's national health insurance and long-term care insurance fee schedules with patient co-payments.

The go-to-market model is community-based and referral-driven: patients are acquired through direct visits, physician referrals, municipal care information systems managed by the Ministry of Health, Labour and Welfare, and care manager referrals, with no paid digital advertising or third-party distribution channels. The free shuttle service for dialysis patients across Nishi-ku, Naka-ku, and southern Minami-ku addresses transportation as a critical barrier for the multi-day-per-week treatment regimen. Leadership is physician-led under Chairperson Kajikawa Emiko, with specialty directors at each facility; ownership is internal with no external investors, parent company, or private equity involvement indicated.

• Aoi-kai Medical Group (葵会): Multi-facility medical corporation operating hospitals, dialysis centers, roken-style elderly facilities, and home care services. Closely mirrors Koujinkai's hospital-plus-dialysis-plus-elderly-care configuration, though serving the Kanto region.
• Hakuai-kai Medical Group (博愛会): Regional Japanese medical corporation operating hospitals, roken, and home care services under an integrated physician-led model. Closely matches the size, scope, and community-anchored operating model of Koujinkai.

Broad incumbents

• Sompo Care (SOMPOケア): Major Japanese operator of paid nursing homes, group homes, day services, and home care under the Sompo Holdings umbrella. Comparable to the elderly-care and home-care components of Koujinkai but at nationwide scale.
• Tokushukai Medical Group: Japan's largest private hospital network, operating acute-care hospitals alongside elderly care facilities and home services. Comparable to Koujinkai as an integrated medical-and-elderly-care group, though at vastly greater scale and geographic reach.
• Solasto (ソラスト): Listed Japanese provider of home nursing, home care, day services, and elderly facility management. Directly comparable to Ashitaba Visiting Nursing Station and Sumire day service, though operating across many more prefectures.
• Nichii Gakkan Company (日医幹): Large Japanese provider of home care, education, and care staffing services, including operating its own home nursing stations. Comparable to the Ashitaba Visiting Nursing Station and care management functions at Koujinkai.
• Tsuji Inc. (ツクイ): Listed Japanese operator focused on day care services, home care, and elderly care facilities, with nationwide coverage. Comparable to the day-care and home-care lines of Koujinkai (Sumire and Ashitaba).

Regional players

• Eikokai Medical Group (永耕会): Japanese medical corporation group operating hospitals and elderly care facilities primarily outside Hiroshima. Comparable integrated medical-and-elderly-care operator competing in adjacent regional markets rather than directly in Koujinkai's catchment area.
