🇯🇵Artificial Intelligence in Japan
32 artificial intelligence providers in Japan, publishing 92 APIs.
Artificial Intelligence in Japan — 32 providers on the APIs.io network sit in both cohorts, and between them they publish 92 indexed APIs.
15 of the 32 publish at least one machine-readable API; 17 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: 12 minimal, 9 emerging, 5 developing, 5 thin, and 1 exemplar.
Leading by rating: LINE, HORIZON SHIELD, SUPER STUDIO, MeetsMore, Magic Moment, Preferred Networks, and 26 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.

Other industries in Japan
Artificial Intelligence elsewhere
This page is the intersection of two independently computed cohorts:
Japan and
Artificial Intelligence. A provider appears here only when it is
already a member of both. Japan membership is matched on tag, stated HQ,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
