Seikokai Group

What Seikokai Group does

Seikokai Group (聖光会メディカルケアグループ / Seikohkai Medicalcare Group) is a private Japanese regional healthcare organization headquartered in Saitama City, Saitama Prefecture, founded in 1981 with the establishment of Kasukabe Kosei Hospital. The group operates through three regulated legal entities — two medical corporations (医療法人聖仁会 Seijinkai and 医療法人光仁会 Kojinkai) and one social welfare corporation (社会福祉法人大幸会 Taikoukai) — running an integrated delivery network anchored by Seibu General Hospital (259 acute-care beds), Kasukabe Kosei Hospital, and Nanbu Kosei Hospital (including a 30-bed palliative care ward), plus outpatient clinics, two home care centers (Seibu and Himawari), and the SaiKou no Mori special elderly nursing home. Services span acute hospitalization, multi-specialty ambulatory care, recovery rehabilitation, home-visit medical and nursing care, daycare, residential care support, sick-child daycare, and a Saitama City-commissioned Comprehensive Community Care Support Center.

The group's care model is built around Japan's regional inclusive care system (地域包括ケアシステム), coordinating patient flow across acute treatment, recovery rehabilitation, home healthcare, and welfare services within a tightly defined two-city catchment (Saitama City Sakura Ward and Kasukabe City). It operates a 70+ member rehabilitation department (43 PTs, 20 OTs, 6 STs as of April 2026) and has refreshed senior clinical leadership in April 2025 with academically credentialed directors from Dokkyo Medical University and Jichi Medical University. A July 2023 data partnership with 医用工学研究所 (Medical Engineering Research Institute) covers pseudonymized clinical datasets for operational and R&D use, but no AI/ML products or proprietary technology platforms are disclosed.

Revenue is generated entirely through patient service delivery billed under Japan's regulated national health insurance fee schedule, on a per-visit and per-episode basis. The customer base consists of regional residents receiving acute, rehabilitative, preventive, and elderly care services; no enterprise clients or non-insurance commercial revenue streams are disclosed. The group is privately held by its operating medical and welfare corporations with no parent company, external investment, or public trading status indicated.
