Medical Corporation Seishikai

What Medical Corporation Seishikai does

Medical Corporation Seishikai (医療法人社団清志会) is a private Japanese medical corporation founded in August 1969 and headquartered in Matsudo City, Chiba Prefecture. The organization operates three integrated facilities serving local residents: Yamamoto Hospital (山本病院), a 60-bed general hospital providing outpatient and inpatient services across internal medicine, gastroenterology, neurology, cardiology, respiratory medicine, surgery, orthopedics, dermatology, urology, rehabilitation, and home-visit care; Okura Kinen Hospital (大倉記念病院), a 150-bed long-term care and rehabilitation hospital with no general outpatient services; and the Kogane Elderly Comprehensive Support Center (小金高齢者いきいき安心センター), a municipally-designated community comprehensive care center providing free consultation, dementia support, rights protection, and preventive care coordination for elderly residents of the Kogane area.

The corporation's product portfolio spans the full continuum of community-based care: primary and specialist outpatient services, inpatient hospitalization, health checkups and corporate examinations (人間ドック・企業検診), day care rehabilitation (大倉記念デイケア), home helper services (ヘルパーステーション), home-visit care planning (居宅介護支援センター), and visiting nursing (訪問看護ステーション). Underlying technology is standard hospital information and referral infrastructure; no proprietary technology platform, AI capability, or digital product surface is disclosed. The corporate website and FAX-based inter-hospital referral process remain the primary channels for service coordination.

Revenue is generated primarily through reimbursements under Japan's national health insurance system for acute/primary care and under the long-term care insurance system for custodial/rehabilitation services. Fee-for-service revenue is derived from health checkups and corporate examinations, while community consultation services at the Kogane Center are provided free of charge, funded indirectly through municipal mandate. The company is privately held under Japanese medical corporation law, with no external private equity or venture capital investment and no public listing. Governance is led by Representative Director Konishi Mari (appointed 2013), with Konishi Hiroiku serving as Director and Manager of Yamamoto Hospital (appointed 1998).
