How do I search the company register in Japan?
Start with gBizINFO / Legal Affairs Bureau (https://info.gbiz.go.jp) for Japan company records. Use the supported legal-name or identifier search and inspect available fields, such as Corporate Number (13-digit), Company name (Japanese/English). Official searches, documents and APIs have separate access rules; LemReveal's free lookup does not remove those conditions.
Step-by-step
- 1
Know which register holds the record
In Japan, company records sit on gBizINFO / Legal Affairs Bureau. Trade directories and aggregator sites are copies — the register is the source of truth.

Search by name or registration number
Use the exact identifier with its issuing register or jurisdiction. Name searches can return several candidates; a number is not a guarantee that the source is available or covers the record.
- 3
Read the register entry, not the marketing page
The register entry shows Corporate Number (13-digit), Company name (Japanese/English). That is what a bank, auditor or counterparty will check.

Keep a dated copy
Register entries change. Save the record with the date you retrieved it, or set up monitoring so you are told when the entry changes.
Frequently asked questions
Is the Japan company register free to search?
Check gBizINFO / Legal Affairs Bureau's current terms for basic searches, profiles, documents and APIs. Not all are necessarily free or available without an account.
Which register is the official one in Japan?

What does a Japan register entry show?
Corporate Number (13-digit), Company name (Japanese/English). Availability of each field depends on what gBizINFO / Legal Affairs Bureau publishes.
Do register entries stay accurate?
Only until the company files its next change. Directors, addresses and status can change without notice, which is why a dated copy — or automatic monitoring of the entry — matters for anything contractual.

KK (株式会社 / Kabushiki Kaisha) is Japan's standard joint-stock company, equivalent to a corporation. Minimum capital is ¥1. It's the most prestigious and common company form for medium to large businesses. Almost all listed Japanese companies are KK.
