Preview build — not the final site
An independent, source-first guide to medical examinations in Japan — what each test finds, and what it doesn't.
People do not usually go looking for "a health checkup". They go looking for an answer to something specific — whether a lump would show up, whether a stomach can be examined without an X-ray, whether a scan can see a problem before it causes symptoms.
This site works the same way. Each examination has its own page: what it detects, who Japan offers it to and how often, what it cannot settle, and where the rules come from. Every factual claim is traced back to a primary source you can open yourself.

Facilities listed from public certification data, with the languages each one supports. No clinic pays to appear here, and nothing is ranked "best" — the order is alphabetical.
