Asbestos CheckEvidence-based checks before construction work in Japan

Evidence ledger

Primary sources and evidence ledger

The checker points to Japanese laws and official guidance. Source titles remain in Japanese so users can identify the controlling publication accurately.

This is an unofficial English explanation. Japanese laws and official Japanese-language sources control.

How to use a source link

Open the official publication, confirm its current date and scope, and compare the relevant provision with the actual project facts. A link in a result is evidence for a check—not a conclusion for the project.

Principal authorities

The source ledger includes e-Gov legislation, Ministry of Health, Labour and Welfare guidance, Ministry of the Environment guidance and reviewed local-government materials.

  • 大気汚染防止法
  • 石綿総合情報ポータルサイト
  • 石綿事前調査結果報告システム

Currency and limitations

Review dates help identify stale material, but only the responsible authority can confirm a current filing procedure. If signed rule status verification fails, the checker stops rather than silently using an older rule state.
