Asbestos CheckEvidence-based checks before construction work in Japan

Japan-specific qualifications

Who is qualified to survey asbestos in Japan?

The right qualification is determined by the asset, work scope and effective date. An English job title or general asbestos certificate may not match the statutory Japanese scope.

This is an unofficial English explanation of Japan-specific requirements. Japanese laws and official Japanese-language sources control.

Buildings (建築物)

For applicable work starting on or after October 1, 2023, confirm a building-material asbestos surveyor qualification covering the building and scope. The detached-house category has a limited scope.

Work structures (工作物)

Requirements applying from January 1, 2026 distinguish official work-structure classes. Classes 1–10 and 11–17 do not necessarily use the same eligible qualification group.

Steel vessels (鋼製船舶)

Use the official vessel route and effective-date guidance. Do not infer eligibility from a building qualification.

  • Ask for the exact Japanese qualification name.
  • Check scope and effective date.
  • Retain evidence with the survey record.
