Kenwakai Medical Association

What Kenwakai Medical Association does

Kenwakai Medical Association (医療法人社団健和会) is a private Japanese medical corporation headquartered in Hakodate, Hokkaido, operating an integrated network of acute orthopedic hospital services and community-based elderly care facilities. Founded in 1946 as Omura Surgical Clinic and formally incorporated as a medical corporation in 1991 under founder Omura Kenji, the organization is now in its third generation of Omura family leadership, with Omura Naohisa serving as representative director since November 2025.

The organization's core clinical asset is Hakodate Omura Orthopedic Hospital, a 56-bed acute care facility offering orthopedic surgery, spinal surgery, artificial joint replacement, hand surgery, pain management via anesthesiology-based pain clinic, and rehabilitation medicine. Supporting facilities include Akamatsunosato Nanae (elderly nursing care), Komorebinosato Nanae (20-room service-supported senior housing), Azumashinosato Nanae (dementia group home including a rare young-onset dementia priority type), and a natural hot spring facility (Yunohikan). Home and community care services span Hakodate and Nanae through care plan centers, visiting nursing, visiting rehabilitation, helper station services, and day rehabilitation. The technology stack is conventional: the Pax electronic medical record system for clinical documentation, on-site MRI and CT imaging, and no disclosed AI or advanced digital capabilities.

Kenwakai generates revenue through four primary streams: medical services revenue from hospital consultations and surgeries covered by Japan's national health insurance; elderly care facility fees from nursing home, group home, and senior housing residents; home care services billed through long-term care insurance on a usage basis; and fee-based health examination packages ranging from JPY 3,500 (basic) to JPY 14,400 (comprehensive). The organization serves orthopedic patients and elderly residents in the Hakodate and Nanae communities of southern Hokkaido through walk-in hospital access and direct facility enrollment, with 101-250 employees across the integrated network.
