How this count is made, and what it leaves out

The figure for Japan is not a soft directory number. Here is exactly what it counts, what it excludes, and how to check it.

What is counted

An organization is counted when it delivers something to a person with the intent of extending healthy years, through clinical care, screening, diagnostics, or a structured preventive program, and when it is published, not closed, and not a duplicate listing. The 6 figure for Japan counts every such organization across all four pillars of the healthspan economy.

What is left out, and how much

  • 1 organization mapped in Japan is held out of this count as a fertility or IVF clinic or a pure booking or telehealth platform: Kato Ladies Clinic . They keep their Atlas entry, they are only outside the geographic count.
  • No organization recorded in Japan is closed.
  • Organizations still under review, and those announced but not yet open, are held back before publication. They carry no place in the published data, so they are counted nowhere in the Atlas, including here.
  • Aesthetic-only providers, product-only companies, investors, publishers, and events are out of scope for the Atlas and are never recorded as organizations.

What this does not claim

The Atlas records, it does not rate. There is no ranking, no score, and no paid placement. No organization pays to appear or to rank, here or anywhere in the Atlas.

How to check

Japan lists every counted organization on this page, with the count broken down by pillar above. The figure is the sum of that breakdown, reproducible line by line. See how the geographic count is derived.

How is longevity medicine regulated in Japan?

Japan licenses a clinic by notification and reviews a regenerative therapy for safety, not efficacy, which lets a clinic deliver certain cell therapies as paid care. No category is specific to longevity.

No dedicated longevity category exists. A clinic is established by notification under the Medical Care Act.
Prefectural governors; Ministry of Health, Labour and Welfare, Medical Care Act (Act No. 205 of 1948), Article 8, as checked July 2026. Primary source .
Under the Act on the Safety of Regenerative Medicine a clinic files a provision plan reviewed by a certified committee for safety and procedure, not efficacy, sorted into three risk classes. This lets a clinic offer autologous stem cell and platelet-rich plasma therapy as self-pay care without product marketing approval.
Ministry of Health, Labour and Welfare; certified committees, Act on the Safety of Regenerative Medicine (Act No. 85 of 2013), in force November 25, 2014. Primary source .
A 2024 amendment extends the regime to in-vivo gene therapy and adds inspection and disqualification powers over the certified committees. Enforcement is by Cabinet Order within one year of promulgation, and the exact enforcement date is not confirmed.
Ministry of Health, Labour and Welfare, Act No. 51 of 2024, promulgated June 14, 2024. Primary source .
Clinical tests ordered as medical practice fall under the Medical Care Act's quality rules. Direct-to-consumer genetic testing sold outside a physician relationship appears to fall largely outside them, and no dedicated binding instrument was found in the sources checked.

High confidence for the regime. The exact enforcement date of the 2024 amendment is not confirmed and is flagged in the amendment entry above.
