🇯🇵Blockchain, Crypto & Web3 in Japan
3 blockchain, crypto & web3 providers in Japan, publishing 1 API.
Blockchain, Crypto & Web3 in Japan — 3 providers on the APIs.io network sit in both cohorts, and between them they publish 1 indexed API.
This cell is below the 5-provider floor, so it carries no generated statistics. A distribution over 3 providers is not a small characterisation of blockchain, crypto & web3 in Japan, it is a wrong one. What follows is the roster and nothing more. The gap is a statement about catalog coverage rather than about the market: Japan holds 124 providers in total and Blockchain, Crypto & Web3 holds 1277, so the intersection being this small is worth reading as a queue of organisations not yet profiled.
Country membership reads a tag or a stated headquarters. A provider lands in Japan when one of its own top-level tags names the country, or when its own description states a headquarters that names the country or one of its cities (roadmap#542, #719). A description that calls a company by its nationality, or names a city in a phrase that is not a headquarters statement, is not counted, so this cell is a floor, not a census.

This page is the intersection of two independently computed cohorts:
Japan and
Blockchain, Crypto & Web3. A provider appears here only when it is
already a member of both. Japan membership is matched on tag, stated HQ,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
