Japan-specific asbestos guidance
Asbestos Check for work in Japan
Understand what to check before demolition, renovation, repair or maintenance work in Japan—without mistaking an informational result for a survey or approval.
Start with the project facts
Japan's requirements depend on the asset, work, effect on existing materials, start date, size and location. The checker keeps those questions separate and explains which facts are still missing.
- Check drawings, specifications and renovation history.
- Do not disturb a material to identify it.
- Confirm the work scope with the principal contractor.
Thresholds are not the whole rule
The often-quoted 80 m² and ¥1 million figures concern particular government-reporting routes. They do not, by themselves, mean that a pre-work survey is unnecessary.
- Pre-work survey (事前調査)
- Qualified surveyor requirements
- Government reporting and advance notice
- Site display, records and local procedures
Use official Japanese information
Every checker result links to the Japanese primary source used by the rule. English explanations are navigation aids only; Japanese laws, ministry guidance and the responsible authority control.
