Medical Plaza

What Medical Plaza does

Medical Plaza (医療法人社団創造会 / Sozokai) is a private Japanese medical corporation founded in 1986 by Dr. Doi in Abiko City, Chiba Prefecture. It operates an integrated healthcare and welfare network built around the 188-bed Heiwadai Hospital, which provides acute care, surgery (over 500 procedures annually), orthopedics, plastic surgery, rehabilitation, dialysis, palliative care, and a Prevention Medical Center. Adjacent facilities span the full care continuum: Kaigo medical facility Espero (95 residents), elderly care facility Kureo (100 beds, all-single-room unit care), dementia group home Vistalio (18 residents in two units), day-service centers (Care Plaza Shibazaki and Kotobuki), serviced senior housing Abiisa Arakino (52 units), a home-visit care center, a patient support center, and a 24/365-day on-site staff nursery. The organization uses an electronic medical record (EMR) system and is JIS Q 15001-compliant for personal information handling.

Revenue is generated primarily through Japan's universal public health insurance (national health insurance and employee health insurance) for medical services and through the long-term care insurance (kaigo hoken) system for eldercare and home-support services, with additional out-of-pocket and elective-service revenue. The go-to-market is purely direct-to-consumer: patients and residents access services at owned facilities in Abiko City, with no franchise, reseller, or third-party channel structure. Customers are local community residents across three primary segments — general patients, elderly individuals requiring long-term care, and employers seeking occupational health services — all served within a single-city geographic footprint in the Kanto region. The organization holds Kurumin (childcare-supporting company) and Health Workplace Declaration certifications and is led by founding chairman Dr. Doi. No private equity, venture capital, or public market participation is referenced.

Revenue model

1. Medical Insurance Services (National Health Insurance / Social Insurance): Revenue is generated through Japan's universal public health insurance system. Medical services at Heiwadai Hospital and affiliated clinics are billed under national health insurance (national health insurance / employee health insurance). Patients pay co-payments per visit or treatment cycle.
2. Long-Term Care Insurance Services (介護保険): Nursing care and welfare services at facilities including Kaigo medical facilities (Espero), elderly care facilities (Kureo), day services (Shibasaki), group homes (Vistalio), and serviced housing for seniors (Abiisa Arakino) are provided under Japan's long-term care insurance system (kaigo hoken). Revenue is generated through per-diem/per-service billing under the insurance scheme.
3. Out-of-Pocket / Premium Services: Certain additional services such as specific examinations, prevention medical check-ups, and some elective care may be billed partially as out-of-pocket expenses or as services outside standard insurance coverage.
