What Shinkokai does

Shinkokai Medical Corporation (医療法人社団進興会) is a private Japanese medical corporation operating a network of 11 health examination clinics across Tokyo, Miyagi, Aichi, and Hokkaido, serving approximately 550,000 patients annually. Founded approximately 30 years ago (circa 1994) and led by Chairman Moriyama Noriyuki, a former Director of the Cancer Prevention and Screening Research Center at the National Cancer Center, the organization specializes in comprehensive health examinations (健康診断) and Human Dock (人間ドック) programs. Its flagship technical offering is a proprietary whole-body MRI screening using Diffusion Weighted Imaging (DWI) that delivers zero-radiation cancer detection across neck, chest, abdomen, and pelvis in approximately 20 minutes, supplemented by 3.0 Tesla MRI, 80-slice multi-slice CT, digital mammography, and advanced endoscopy equipment. The company also recently introduced M-Vision Health, an AI-assisted brain MRI risk-assessment service for dementia and stroke prediction.

The business operates a hybrid B2B/B2C model with multiple revenue streams: self-pay human dock packages ranging from ¥47,850 (Day-Trip Human Dock) to ¥275,000 (MRI Executive Dock, 3-session method); corporate enterprise contracts managed by dedicated sales representatives; government-mandated Specific Health Examinations and Specific Health Guidance (特定健診・特定保健指導) priced up to ¥13,200-¥33,000 per person; insurance union-covered examinations; vaccinations; industrial physician contracts; and mobile (巡回) workplace screenings covering the Kanto region. Distribution is primarily through owned facilities (11 clinics in commercial hubs such as Shimbashi, Osaki, Nihonbashi Hamacho, Tachikawa, Sendai, Nagoya, and Sapporo), supplemented by mobile examination services, a self-serve web reservation platform, and a referral network with major specialty hospitals including Toranomon Hospital, Cardiovascular Institute Hospital, IMS Kinen Hospital, and St. Luke's International Hospital. Certifications include the Japan Society of General Medicine facility certification (since April 2005), the Human Dock Facility Functional Evaluation certification (May 2025), and the JIPDEC Privacy Mark. The organization has no disclosed external funding, operates as an independent medical corporation under Japanese law, and is governed by a board led by the founder.
