Understand the safety and regulatory picture before you plan a trip.
This page explains how Japan regulates regenerative medicine, how licensed physicians and medical institutions confirm eligibility and treatment availability, and — just as importantly — what StemCellor cannot promise. Read it before deciding whether to travel, not after.
Japan's regenerative medicine framework
Regenerative medicine in Japan is governed by the Act on the Safety of Regenerative Medicine, which classifies treatments into three risk-based categories and requires each provider to submit a regenerative medicine provision plan for review by a certified regenerative medicine committee before treatment can begin. For an autologous adipose-derived stem cell infusion being considered for an individual case, the receiving licensed physician or medical institution confirms the applicable regulatory pathway before treatment is offered.
This framework exists to review a clinic's processes — screening, cell processing, and post-treatment monitoring — before treatment starts. It is a review of process, not a certification or guarantee of any individual patient's outcome.
Regenerative medicine offered under this framework is elective, self-pay care and is not covered by Japan's national health insurance system. See our Pricing page for what a treatment plan typically costs.
Eligibility review before treatment
Every prospective patient's history is reviewed by a licensed physician before any treatment plan is proposed, and before any travel is planned — not by a booking coordinator, and not as part of a sales consultation.
This review happens deliberately first. Travel and treatment planning follow only once your physician has reviewed your candidacy, not the other way around.
Some patients may be advised to delay treatment until a specific condition is stabilized, or advised not to proceed at all. This is a normal, expected outcome of a genuine review process — not a rare exception.
No specific treatment outcome or eligibility result is guaranteed at any stage of this review.
Cell processing and clinical environment
For stem cell therapy, cells collected from your own tissue are cultured and purified at a cell-processing facility under controlled, clean-room conditions over several weeks. Only cells confirmed sterile and genetically stable are released for use.
We describe our processing conditions in these general terms deliberately. We do not claim a specific third-party facility certification, a named partner facility, or an affiliation with another institution unless that relationship has been independently confirmed as accurate — plainly describing what we can confirm today is a smaller risk to you than an unconfirmed claim.
If you have questions about processing standards for a specific treatment, ask your physician directly during your consultation. This is a reasonable, expected question, not an unusual one.
Risks, limitations, and what cannot be promised
Minor risks are possible with any procedure involving tissue collection or injection — for example localized pain, swelling, bruising, or infection at the treatment site. Rare systemic reactions have been reported in the wider clinical literature on autologous cell-based therapies. Your physician reviews the risk profile relevant to your specific treatment during your eligibility review, before you consent — not after treatment has begun.
A guaranteed treatment outcome, for any treatment on this site.
That any treatment cures a diagnosed disease. Our protocols are not a substitute for treating a medical condition through conventional care.
That any treatment reverses the aging process. Our regenerative and longevity protocols are intended to support the body's own regenerative, circulatory, and metabolic capacity — not to reverse aging.
Guaranteed eligibility. Candidacy is confirmed individually by a physician, and some prospective patients are advised not to proceed, or to delay treatment.
That your individual response will match anyone else's. Response to any regenerative or longevity treatment varies with age, health status, and treatment goals.
Visa or immigration approval, or any other decision made by a third party or government authority — we provide guidance and support, not the decision itself.

Frequently Asked Questions
01Is regenerative medicine legal in Japan?
Yes. Regenerative medicine is legal in Japan and is governed by the Act on the Safety of Regenerative Medicine, which classifies treatments by risk level and requires provider review by a certified regenerative medicine committee before treatment can begin. The receiving licensed physician or medical institution confirms the regulatory pathway that applies to any treatment being considered for an individual case.
02Does StemCellor have a regulatory plan number?
Regenerative medicine in Japan is provided under specific medical and regulatory requirements, confirmed case by case. StemCellor coordinates information and appointment planning; the receiving licensed physician or medical institution confirms the applicable regulatory category and whether a treatment can be appropriately offered for your case. StemCellor does not itself diagnose, and does not guarantee eligibility or treatment availability.
03Who reviews my eligibility?
A licensed physician reviews every prospective patient's history and candidacy — not a booking coordinator, and not as part of a sales consultation. This review happens before any treatment plan or travel itinerary is discussed.
04Can treatment results be guaranteed?
No. No specific treatment outcome is guaranteed for any treatment on this site. Individual response varies with age, health status, and treatment goals, and your physician will discuss what is realistically achievable for your case rather than a fixed result.
05What if I'm not suitable for treatment?
Your physician will tell you directly and explain why — whether that means a treatment isn't appropriate for your case or should be delayed until a specific condition is addressed. Not every prospective patient is advised to proceed, and that's an expected outcome of an honest review, not a failure of the process.
06How are cells processed?
For stem cell therapy, cells collected from your own tissue are cultured and purified at a cell-processing facility under controlled, clean-room conditions over several weeks, and only cells confirmed sterile and genetically stable are released for use. We don't claim a specific third-party facility certification or name a partner institution unless that relationship has been independently confirmed.
07Is travel arranged before my physician review?
No — we recommend against it. Travel should not be arranged until your physician eligibility review is complete, so your trip isn't booked around a treatment plan that hasn't been confirmed yet. See our International Patients guide for a fuller timeline.
08What happens after I return home?
Follow-up arrangements, including any remote review, are confirmed case by case by the receiving physician or medical institution. They do not replace local emergency care — for urgent symptoms, seek care from a local medical provider first.
Let us understand the case before anyone recommends a plan.
Share your goals, medical background, and travel window. StemCellor will help organize the next step around physician review, realistic expectations, timing, and reference cost.
Direct messaging channels are still being confirmed — for now, start through the international patient guide.
Send the main concern, treatment goals, and any medical history that may affect candidacy.
We help clarify which treatment area may be worth discussing before travel is planned.
When appropriate, the case is prepared for physician review and visit planning in Japan.
