Japan & Korea × Construction

Construction in Japan & Korea

5 construction providers across Japan & Korea, publishing 31 APIs.

5 providers 31 published APIs 31 indexed documents

Construction across Japan & Korea — 5 providers on the APIs.io network sit in both cohorts, and between them they publish 31 indexed APIs.

4 of the 5 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: 2 minimal, 1 developing, 1 thin, and 1 emerging.

Leading by rating: HORIZON SHIELD, Den, ANDPAD, Sankun, and Planby Technologies.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.

This page is the intersection of two independently computed cohorts: Japan & Korea and Construction. A provider appears here only when it is already a member of both. Japan & Korea membership is matched on tag, name pattern, 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 region here is available over the APIs.io API and to AI agents over MCP.
