KOAIKAI MEDICAL

What KOAIKAI MEDICAL does

KOAIKAI MEDICAL (医療法人宏愛会) is a privately held Japanese medical corporation founded in 1988, operating an integrated medical and elderly care network across Ota City and Kiryu City in Gunma Prefecture. The organization originated as Shinohara Surgical Clinic in 1975 and has expanded over five decades into a family-controlled group operating 8 facilities: Koaikai Daiichi Hospital (123 beds, all private rooms, designated emergency hospital), Shinohara Clinic (19 beds), two nursing care facilities — Koai-en (90 beds) and Nursing Care Kawanouchi-no-Mori (100 rooms) — four residential-type paid elderly homes (Rikyuu 30, Bashou 62, Kochou 37, Choumei 50 rooms), and a day service center. The group also operates the Ota Regional Rehabilitation Wide-area Support Center designated by Gunma Prefecture since 2005 and launched a Home Visit Care Station in January 2024.

The core technology and IT infrastructure is standard hospital-grade, with SSL encryption and Google Analytics on its web properties, and adoption of Japan's national online eligibility verification system (using My Number card for health insurance) at both the clinic (November 2023) and the hospital (April 2026). No proprietary AI, ML, or platform technology is evidenced; differentiation rests on regulatory designations (long-term care insurance designated facilities, regional rehabilitation support center, emergency hospital designation) and the integrated care coordination across owned facilities rather than on technology.

The business model is reimbursement-driven under Japan's universal health insurance and long-term care insurance systems, supplemented by private pay for residential fees (rooms ¥9,000-24,000/month, management fees ¥23,100-33,000/month, meals ¥61,980/month at one facility), with zero entrance fees across facilities. Additional revenue streams include day rehabilitation fees (¥528-989 per session based on long-term care insurance units and care level), comprehensive health checkups (¥38,500 for a full-day package), and various optional add-ons. The organization employs approximately 300 staff as of February 2023, is led by Chairman and Hospital Director Arai Kosuke, and operates without external institutional capital or private equity investment.
