🇯🇵Artificial Intelligence in Japan

39 artificial intelligence providers in Japan, publishing 105 APIs.

39 providers 105 published APIs 149 indexed documents

Artificial Intelligence in Japan — 39 providers on the APIs.io network sit in both cohorts, and between them they publish 105 indexed APIs.

19 of the 39 publish at least one machine-readable API; 20 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 17 minimal, 9 emerging, 7 developing, 4 thin, 1 exemplar, and 1 strong.

Leading by rating: LINE, SUPER STUDIO, MeetsMore, HORIZON SHIELD, ai-akari-ai, Magic Moment, and 33 more.

Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in Japan when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.
