Key takeaways

  • Start by confirming the supplier's legal entity.
  • Use Corporate Number and Japanese registered name before interpreting risk records.
  • Review public enforcement, public-risk, and subsidy records where relevant.
  • Preserve the reviewed source URLs and decision notes.

Practical workflow

  1. 1Collect supplier legal name, Japanese name, Corporate Number, website, address, and contact domain.
  2. 2Search the supplier in RegBase and confirm identity signals.
  3. 3Review enforcement records by regulator, law, action type, and date.
  4. 4Check public-risk and subsidy-fraud disclosures when the supplier profile makes them relevant.
  5. 5Save an evidence report and record the internal decision or escalation path.

The first-pass checklist

A useful Japan supplier due diligence checklist should separate identity, public-source risk, and internal decisioning. Mixing those steps creates confusion and makes it harder to defend an approval or escalation later.

RegBase supports the public-source layer. It helps teams identify the company, find public records, open source URLs, and save an evidence report for review files.

  • Identity: registered name, Corporate Number, address, website
  • Public records: enforcement, warnings, public risk, subsidy records
  • Evidence: source URLs, generated report, reviewer notes
  • Decisioning: approve, clarify, escalate, or reject under internal policy

When a record should trigger escalation

Escalation depends on your internal policy, but common triggers include recent business suspension orders, repeated regulatory actions, unresolved source ambiguity, public subsidy fraud disclosures, or records tied to the same products or services you plan to buy.

The goal is not to reject every supplier with a record. The goal is to make sure the right person reviews the right evidence before onboarding or renewal.

How to preserve the review trail

For each screened supplier, keep the search date, search terms, matched company page, Corporate Number context, original source URLs, and a short note explaining the review outcome.

Important limitation

RegBase supports public-source screening and evidence collection. It is not a credit report, sanctions result, legal opinion, or final due-diligence conclusion.
