Where to check Japanese procurement suspensions
Japanese procurement suspension information is published by individual authorities. This English directory explains how to use three official starting points and what each one covers. It is a selected reference, not an exhaustive list of central or local government authorities.
Source coverage and RegBase coverage are different
The links below identify publishers. They do not certify a supplier’s eligibility or guarantee that RegBase holds every record. Check the current procurement coverage report (Japanese) and English data-sources explanation before relying on database results.
The World Bank’s Global Suspension & Debarment Directory, Japan entry (2025) provides background on Japan’s agency-specific framework. The original agency notice controls the scope of each measure.
