Established in 1964, Medical Corporation Yamamoto Iin has served community medicine for three generations. On that foundation, Cellforce One Clinic Tokyo now delivers the next era of medicine — regenerative, preventive, personalized — from the heart of Ginza.
Japan's super-aged society has reached a turning point in medical economics. Rather than waiting for insurance coverage to catch up, we believe in the proactive protection of one's own body through three layers: prevention, early intervention, and regeneration. Our integrated care experience unites precision imaging, cellular therapy, and concierge coordination under one philosophy.
In the year of the Tokyo Olympic Games — as Japan transitioned from post-war reconstruction to high-growth modernization — Yamamoto Iin was established as a community medical practice. Three generations of medical succession begin here.
Japan became the first country in the world to establish a comprehensive legal framework for regenerative medicine (Act No. 85 of 2013, effective 2014). Regulatory infrastructure for clinic-level cellular therapy delivery was formally established.
Cellforce One Clinic Tokyo (CFO) opens in Ginza. Built on the medical legacy of Yamamoto Iin, the clinic integrates regenerative therapy, preventive care, and precision imaging, with dedicated inbound patient capability.
Presented at the 91st China International Medical Equipment Fair (CMEF 2025) and the Medical AI Innovation Forum. CFO began global thought-leadership on precision regenerative medicine.
The clinic organizes filed regenerative-medicine provision plans, cell-processing and operational contracts, physician review, informed consent, quality confirmation, and periodic reporting.
Filed / notified under Japan's Act on Safety of Regenerative Medicine (Act No. 85 of 2013). The clinic manages MSC chronic pain plans (PB3240161 / PB3250154) and MSC osteoarthritis plans (PB3240166 / PB3250155), with physician review before any treatment decision.

The clinic manages filed provision plans, cell-processing and operational contracts, informed-consent flow, quality confirmation, and reporting obligations. Details are reviewed by the physician for each patient.
For each provision plan, the clinic confirms cell-processing facility, quality checks, transport and storage conditions, and treatment schedule.
