Check any Japanese company.
Free company verification and import tools built on the official Japanese registers — the National Tax Agency invoice registry, gBizINFO, customs notices, METI/MIC databases and Japan Post data.
Company search — T-number & license check
One search for everything: a company name (all 5.79M registered companies — kanji, kana or romaji), a T-number / corporate number (invoice status and licenses together), or browse by license type.
What license data is included?
License and certification data is combined from several official sources:
- gBizINFO notifications & certifications (METI, ~132,000 records / 128 types, monthly): FSA financial licenses (securities, moneylenders, banking & insurance, funds transfer, crypto-asset exchanges…), METI / SME Agency certifications (DX, management-improvement and business-continuity plans…), MHLW certifications (Youth Yell, Monisu…).
- Unified government bidding qualification (統一資格): when you look a company up by number, its qualification (grades per category) is checked against the official GEPS roster and cached — full coverage, not just the gBizINFO subset.
- Construction business licenses (建設業許可): loaded prefecture by prefecture from the official prefectural rosters, matched to corporate numbers (currently 秋田県; more prefectures are added on the monthly refresh). A few records confirmed from official rosters are added manually and marked as such.
- Representative names: from gBizINFO basic info (monthly; available for ~43,000 companies — mostly larger/active ones).
⚠️ Real-estate licenses, electrician registrations and construction licenses of prefectures not yet loaded are not searchable here — verify those in MLIT's official search system.
Invoice-registration status: NTA Qualified Invoice Issuer Publication Site, refreshed daily. Contains processed data from gBizINFO (METI) and the GEPS procurement system.
Everything here is also a free JSON API (attribution required).
