About Japan company search
Every registered entity in Japan holds a 13-digit corporate number (法人番号) issued by the National Tax Agency, and larger companies also publish structured data through gBizINFO. A Japan company search returns the corporate name in Japanese and Latin script, the corporate number, registered address, incorporation date, entity type (KK — kabushiki kaisha, or GK — godo kaisha) and status. Search in English by name or corporate number.

How to search the gBizINFO / Legal Affairs Bureau

- 3
Obtain Official Registry via Legal Affairs Bureau
For certified legal documents (Touki-jikou-shoumeisho), use the 'Touki-jouhou-teikyou-service' portal. This requires a paid account or guest login to view official registry records.
Who uses this data
Global compliance officers conducting KYB, procurement teams sourcing Japanese manufacturing partners, and legal researchers verifying the representative directors and capital structures of KK and GK entities.
Access, fees & notes
While gBizINFO provides broad data for free, it is an aggregator. The definitive legal record remains the Registry of the Legal Affairs Bureau, which requires a fee for each document viewed. English names are not always officially registered; searching in Japanese characters (Kanji/Katakana) is recommended.
Cost & access
gBizINFO and NTA portal searches are free. Official registry extracts (Touki) from the Legal Affairs Bureau cost approximately 330-600 JPY per document.

Common mistakes to avoid
✗ Using a 12-digit Individual MyNumber instead of the 13-digit Corporate Number.
✓ Corporate numbers always have 13 digits; verify the number on the NTA portal before searching.
✗ Ignoring suffixes when searching for branch offices.
✓ Japanese companies often have branch registrations (Shiten); check the address fields to ensure you are looking at the head office (Honten).
Frequently Asked Questions
What is a KK (Kabushiki Kaisha)?▾
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.
What is a GK (Godo Kaisha)?▾
GK (合同会社 / Godo Kaisha) was introduced in 2006, modeled after the US LLC. It's cheaper and simpler to establish than a KK, with no minimum capital. Many foreign companies (including Amazon Japan and Google Japan) use GK.
How do I search Japanese companies?▾
gBizINFO (info.gbiz.go.jp) provides free search in Japanese and limited English. The National Tax Agency also provides a Corporate Number search at houjin-bangou.nta.go.jp. For detailed filings, access the EDINET system for listed companies.
What is the Corporate Number system?▾
Since 2015, every Japanese corporation receives a unique 13-digit Corporate Number (法人番号). It's used for tax, social insurance, and government procurement. The number is publicly searchable and freely available.
How do I search for a company in Japan by name?▾
Use the available lookup or the linked official Houjin Bangou service. Start with the legal name, then compare the exact Corporate Number number and available identity fields. Name matches are candidates; source coverage and partial-name support vary.
Is the Japan company register free to search?▾
Basic company lookup is free on LemReveal. The official Japan register has independent access rules and may require an account or charge for searches, extracts or particular documents. Check the source's current terms.
Can I search Japan companies by registration number?▾
Where the source supports it, use the exact Corporate Number number together with its register or jurisdiction. Preserve prefixes and leading zeros and compare the returned legal name. A number alone does not guarantee coverage or a successful lookup.
How do I check whether a company is registered in Japan?▾
Search the exact Corporate Number number or legal name above, then confirm the entity's identifier and source. An empty result can reflect coverage limits, a source outage, spelling or a different jurisdiction; it does not prove the business is unregistered. A fuzzy candidate is not a confirmed identity.
How can I tell if a Japan company is still active?▾
Read the status and effective date where the Houjin Bangou supplies them. Active registration does not establish trading or financial health. Monitoring is available only for supported sources and confirmed records; verify the actual watch state.
How do I find a company's Corporate Number number?▾
Identify the legal entity using the available lookup or official Houjin Bangou route. Record the Corporate Number only where supplied, with its source and jurisdiction. Do not infer missing identifiers from a similar name.
