Seijinkai Designated Medical Corporation

What Seijinkai Designated Medical Corporation does

Seijinkai Designated Medical Corporation (特定医療法人 誠仁会) is a private, non-profit-oriented medical corporation founded in August 1976 under Japan's Designated Medical Corporation framework (designated March 1991). It operates a 199-bed multi-functional general hospital, Okubo Hospital, in Akashi City, Hyogo Prefecture, providing acute care, emergency medicine, outpatient services, inpatient hospitalization, palliative care, and health examinations across 14+ clinical departments including internal medicine, cardiology, nephrology, orthopedics, neurosurgery, and obstetrics/gynecology.

The organization's core product is integrated healthcare delivery anchored on two specialty surgical centers established in 2017: the Akashi Okubo Joint Replacement Center, performing approximately 200 knee and hip arthroplasties annually with ~30-minute operation times, and the Akashi Spine Surgery & Lower Back Pain Center, performing 216-294 spine surgeries annually (growth from 180 cases in 2017) using advanced technology including the NVM-5 spinal cord monitoring system, spinal navigation, and microendoscopic discectomy (MED). Spine Center Director Ishii Takaharu brings approximately 3,000 lifetime surgical cases since 2004. The rehabilitation department (~30 staff) operates with ultrasound imaging capabilities, Pilates-based therapy, and published research output, including a 2025 peer-reviewed paper in AP-SMART journal.

The business model is revenue from Japan's national health insurance reimbursement schedule for clinical services, supplemented by subscription-based senior housing (Okubonosato with 36 rooms adjacent to the hospital at ¥60,000-85,000 monthly rent plus service fees), health examination programs, dialysis services, and an integrated care continuum spanning two visiting nursing stations, two senior housing facilities, an elderly care facility (Hirano), regional comprehensive support centers, and care plan centers across Akashi City and Kobe's Nishi Ward. Distribution is direct-to-consumer through hospital outpatient visits, referrals via the regional medical coordination conference network (15th iteration held March 2025), and community health seminars. The organization operates without external PE/VC capital or public listing, is self-sustaining through medical fees, and has not disclosed revenue figures.
