Concept
What we stand for
Certification
Filed with, and accepted by, the regional bureau of health
Certified.
These are the cover sheets of the filings, in the original Japanese. The full documents can be viewed at the clinic.
Japanese law requires that regenerative medicine may be offered only after a rigorous review — by a Certified Special Committee for Class 2 treatments, and by a Certified Committee for Class 3 — covering the validity and safety of the treatment, the medical staffing, and the management of cell processing. The resulting treatment plan must then be filed with, and accepted by, the Kanto-Shinetsu Regional Bureau of Health and Welfare.
We have filed both Class 2 and Class 3 treatment plans with the bureau, and both have been accepted — making us a registered provider of regenerative medicine. Each filing passed the rigorous review of the relevant certified committee, whose written opinion we hold.

Regenerative Medicine
Treatments
An advanced regenerative treatment using stem cells taken from your own tissue and cultured, aiming at the recovery of damaged tissue and lost function, and at age care worked at the level of the cell. Because the cells are your own, rejection is unlikely.
Cost: discussed with your doctor
All treatments are private and not covered by Japanese public health insurance. Safety, side effects and other details are explained by a doctor at your consultation. Some treatments use pharmaceuticals or ingredients that are not approved in Japan.

FAQ
Frequently asked questions
All treatments are private and not covered by Japanese public health insurance. The cost is presented as a single total at your consultation, together with the treatment plan.
Under Japan's Act on the Safety of Regenerative Medicine, a clinic may offer these treatments only after review by a certified committee — a Certified Special Committee for Class 2, a Certified Committee for Class 3 — and must then file its treatment plan with the Kanto-Shinetsu Regional Bureau of Health and Welfare. We have made those filings and they have been accepted.
A doctor examines you and explains the treatment, the cost and the safety data in full before anything begins. You decide whether to go ahead after you have heard all of it.
A doctor will examine you and recommend a treatment based on your condition and what you are aiming for. Start by contacting us on WhatsApp or by phone.
We work with Keio University Hospital and Tokyo Saiseikai Central Hospital, covering pre- and post-treatment testing and, should it ever be needed, transfer of care.
You are reading our English site, which mirrors the Japanese one. For enquiries in English, please use the contact form or phone us — we will arrange an English-speaking response. Please note that the official store and our privacy policy are currently available in Japanese only.
We suggest checking these seven points. We meet all of them.
Yes, we see patients by appointment. Book on WhatsApp or by phone (+81-3-6434-0758). We are open Mon–Sat and holidays 11:00–21:00, and Sun 11:00–19:00.
Four things make comparison easier: whether the purity of the raw material is published, whether the plant is GMP-certified, whether it is NMN alone or formulated with ingredients that support how it works, and whether a doctor or specialist was involved in designing the formulation. We supply NMNMASTER, our own doctor's supplement.
