Your free National Tax Agency Houjin-Bangou Web-API application ID. Register free at https://www.houjin-bangou.nta.go.jp/webapi/ (issued within 1 business day, no commercial restriction). Without an ID, the actor returns a curated reference dataset of well-known Japanese corporations covering all 47 prefectures and all corporate types — useful for schema validation, KYC pipeline development, and B2B prospecting demos. With an ID, the actor hits the live NTA Web-API v4 endpoints (/4/num, /4/name, /4/diff) and returns real registry rows.
