Financial Technology in Japan & Korea

21 financial technology providers across Japan & Korea, publishing 17 APIs.

21 providers 17 published APIs 96 indexed documents

Financial Technology across Japan & Korea — 21 providers on the APIs.io network sit in both cohorts, and between them they publish 17 indexed APIs.

10 of the 21 publish at least one machine-readable API; 11 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 thin, 6 minimal, 5 emerging, 1 exemplar, 1 strong, and 1 developing.

Leading by rating: PAY.JP, PortOne, Payple, LayerX, Toss Payments, KOMOJU, and 15 more.

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 Financial Technology. 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.
