81 providers 225 APIs

Japan on the APIs.io network surfaces 81 providers that carry a Japan tag — together publishing 225 indexed APIs.

Notable providers include PAY.JP, LINE, KUFU, Soracom, JPX (Japan Exchange Group), Logiless, and 75 more — each profile links out to that provider’s APIs, schemas, and governance artifacts.

Related countries by shared providers: Singapore. Browse every country at countries.apis.io.

Country mapping is derived from the country tags providers carry — it surfaces what is explicitly signalled in the structured data and intentionally does not infer geography further. Most providers carry no country tag, so coverage is deliberately partial; many companies also operate across multiple countries, and cross-listings are expected.
