B2B Database Japan

The National Tax Agency (NTA) assigns Corporate Numbers (法人番号) to all Japanese legal entities. Our database sources from the NTA, Legal Affairs Bureau, and other official registries, enriching each record with global business intelligence and corporate ownership structures.

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.

P&L and balance sheet data is not currently available for Japan. We provide revenue estimates, employee counts, industry classifications, and corporate ownership data.

Yes. All data is sourced from publicly available business registers and complies with both GDPR and Japan’s Act on the Protection of Personal Information (APPI).

Yes. Our REST API allows you to look up any Japanese legal entity by Corporate Number (法人番号), company name, or address. Unlike the official NTA lookup, CompanyData returns enriched data including corporate ownership, industry classifications, and contact details — all in a single API call. The same API key works for 200+ countries, making it ideal if you need company data beyond Japan.

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.
