What Medical corporation Kiyokai does

Medical Corporation Kiyokai (医療法人社団紀洋会) is a private Japanese healthcare and elderly care organization headquartered in Tambasasayama City, Hyogo Prefecture, operating since 1994. Its core service portfolio is built around Okamoto Hospital (岡本病院), an acute-care facility offering 24-hour emergency services and multiple specialty departments, paired with an extensive integrated Kaigo (介護) Group that provides the full continuum of elderly care. The care network includes Sakuraso (咲楽荘) nursing rehabilitation, Fukinonosato (ふきの郷) medical nursing care facility, nine group homes, multiple day service centers, home-visit nursing, home-visit rehabilitation, day rehabilitation, small-scale multifunctional home care, care management services, and the Green Leaf (グリーンリーフ) fee-based nursing home. The organization serves local residents of Tambasasayama, Tamba City, and Sanda City in Hyogo Prefecture, with elderly and disabled care recipients as the primary segment alongside general community medical needs.

The company's revenue model is anchored in Japan's national health insurance and long-term care insurance reimbursement systems, with a supplementary private-pay stream from the fee-based Green Leaf facility. Pricing is regulated under standardized co-payment structures tied to age, income, and care level. Its technology stack is primarily standard healthcare IT infrastructure augmented by an AI-powered pre-visit questionnaire (AI来院前問診) launched in August 2024 to streamline patient intake. Distribution is fully direct: services are delivered through owned hospital and care facilities or via home-visit staff, with no third-party resellers or partner channels. The organization also operates a 24-hour on-site nursery (ぽっぽ保育園, since 1994) to support staff retention in the caregiver labor market.

Kiyokai's competitive position rests on its vertically integrated care continuum within a rural Hyogo geography, its regulated medical corporation status, and a sustained track record of workplace certifications (Kurumin, Mimosa, Hyogo Work-Life Balance Promotion Company). Leadership is headed by Chairman Yoda (余田理事長). There is no disclosed external investment, no parent company, no M&A activity, and no public listing, making Kiyokai a stable, regionally anchored operator whose growth trajectory is bounded by Japan's demographic-care demand and public insurance fee schedules rather than by capital-driven scaling.
