Sales region
Japan & Korea
Japan and South Korea — high-density industrial and consumer-tech API markets.
15 providers
119 APIs
Japan & Korea on the APIs.io network surfaces 15 providers mapped to this sales region — together publishing 119 indexed APIs.
Notable providers include Soracom, Samsung, Toyota, LINE, Coupang, Nissan, and 9 more — each profile links out to that provider’s APIs, capabilities, schemas, and governance artifacts.
Region mapping is derived from provider tags and provider-name pattern matching — it surfaces what is explicitly signalled in the structured data and intentionally does not infer further. Many providers operate across multiple regions; cross-listings are expected.
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.
