Sales region

Japan & Korea

Japan and South Korea — high-density industrial and consumer-tech API markets.

233 providers 686 APIs

Japan & Korea on the APIs.io network surfaces 233 providers mapped to this sales region — together publishing 686 indexed APIs.

Notable providers include LINE, PAY.JP, TheCarApi, Actionpower, 3-shake, PortOne, and 227 more — each profile links out to that provider’s APIs, schemas, and governance artifacts.

Related regions by shared providers: Southeast Asia, Greater China, and Europe. Browse every sales region at regions.apis.io.

Region mapping is derived from three explicit signals: a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. It surfaces what is signalled and intentionally infers no further — a provider that says nothing about where it is appears in no region at all. This is a map of stated headquarters, not of markets served. A London company selling across Europe is listed under United Kingdom & Ireland only, and several of the largest API providers carry no geographic statement of any kind, so they appear here nowhere.

About this region

APIs from Japan and South Korea. Two of the world’s most mature industrial economies, with strong API concentration in manufacturing, automotive, robotics, gaming, and the deep B2B consumer-tech integrations that power both markets.
