Frequently Asked Questions
Common questions about our company database.
A Corporate Number (法人番号, Hōjin Bangō) is a unique 13-digit identifier assigned by the National Tax Agency to every Japanese legal entity. Our database includes Corporate Numbers for 6,390,884 of the 6,602,965 entities.
Our database covers: K.K. (株式会社 — stock company), G.K. (合同会社 — limited liability company), G.S.K. (合名会社 — general partnership), government bodies, NPOs, and more.

Firmographic data (company details, addresses, industry codes) is refreshed on a rolling basis from the National Tax Agency and Legal Affairs Bureau registries. Corporate ownership and contact data is updated as new filings and records become available.
