Quick public-record checks

  1. 1Search by English name, Japanese registered name, or Corporate Number.
  2. 2Confirm the 13-digit Corporate Number when it is available.
  3. 3Check whether an English company name comes from an official source.
  4. 4Review public enforcement and public-risk records before relying on a match.
  5. 5Save the company evidence report with source URLs for internal review.

What a Japanese company registry check should answer

Most overseas searches start with a simple question: is this Japanese company real, and am I looking at the right entity? In Japan, the safest first step is to match the registered Japanese name, address context, and Corporate Number rather than relying only on an English rendering.

RegBase is designed to make that first pass easier in English. It brings company identity context together with public enforcement records and source links so a compliance, procurement, or investment team can decide whether a counterparty needs deeper review.

  • Registered Japanese name and address context
  • Corporate Number and company status where available
  • Official-source English name labels when recorded
  • Public enforcement and public-risk links tied to the entity

Why the Corporate Number matters

A Japanese Corporate Number is a stable 13-digit entity identifier. It is often the cleanest way to reduce false matches when English names vary, a company has multiple romanizations, or a group contains similarly named entities.

For material decisions, use the Corporate Number as a matching anchor and then review original public-source URLs before drawing a conclusion.

Where RegBase adds evidence beyond basic identity data

Basic registry information helps identify a company, but overseas teams usually need more than identity. RegBase connects the company profile to public administrative enforcement, public-risk disclosures, Official Gazette company notice metadata, and source evidence where available.

This makes RegBase a public-source evidence layer, not a credit score or legal conclusion.

  • Administrative enforcement actions by regulator, law, and action type
  • Public-risk disclosures such as selected labor, financial warning, and subsidy records
  • Original Japanese source links and preservation status where available
  • Company-level public-record evidence reports for internal files

When to escalate beyond public records

A clean public-record search does not prove that a company is safe. It only means RegBase did not find a matching public record from its collected sources. Escalate when the counterparty is high value, high risk, difficult to match, newly formed, or operating in a regulated sector.

Important limitation

RegBase is a public-source screening and evidence workflow. It is not a credit report, sanctions result, legal opinion, or final due-diligence conclusion. Verify material records against the original Japanese source.
