🇯🇵Telecommunications & Connectivity in Japan

8 telecommunications & connectivity providers in Japan, publishing 31 APIs.

8 providers 31 published APIs 101 indexed documents

Telecommunications & Connectivity in Japan — 8 providers on the APIs.io network sit in both cohorts, and between them they publish 31 indexed APIs.

6 of the 8 publish at least one machine-readable API; 2 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: 3 minimal, 2 thin, 1 exemplar, 1 strong, and 1 emerging.

Leading by rating: LINE, Soracom, Rakuten, NTT Docomo, NTT, Rakuten Mobile, and 2 more.

Country membership reads a tag or a stated headquarters. A provider lands in Japan when one of its own top-level tags names the country, or when its own description states a headquarters that names the country or one of its cities (roadmap#542, #719). A description that calls a company by its nationality, or names a city in a phrase that is not a headquarters statement, is not counted, so this cell is a floor, not a census.

This page is the intersection of two independently computed cohorts: Japan and Telecommunications & Connectivity. 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.
