Tokachidake: Volcanic Alert Level 3 / mountain access restrictions JMA raised the alert to Level 3 at 09:30 JST on 12 September 2026 and confirmed it remained in force at 16:00 JST on 14 September. Large ballistic rocks may affect roughly 3 km around the crater. Follow current local-government instructions for actual prohibited areas and road closures.
The route descriptions and map markers below include records from before the upgrade. References to Level 2, 1.5 km, or being outside restrictions are outdated and do not establish current access. The old 1.5 km restriction circle is hidden. We have not drawn a new restriction boundary.
