🇯🇵Government & Public Sector in Japan

7 government & public sector providers in Japan, publishing 6 APIs.

7 providers 6 published APIs 6 indexed documents

Government & Public Sector in Japan — 7 providers on the APIs.io network sit in both cohorts, and between them they publish 6 indexed APIs.

6 of the 7 publish at least one machine-readable API; 1 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: 7 emerging.

Leading by rating: Graffer, BODIK ODCS, DATA GO JP, e-Gov Data Catalog, Gifu Prefecture Open Data, Tokyo Metropolitan Open Data, and 1 more.

Country membership is exact-tag only. A provider lands in Japan when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a government & public sector company headquartered in Japan that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

This page is the intersection of two independently computed cohorts: Japan and Government & Public Sector. A provider appears here only when it is already a member of both. Japan membership is matched on tag, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
