To Hikers Planning to Climb Mt. Asama

As of August 19th, 2019 at 11:00 a.m., the Japan Meteorological Agency has lowered the Volcanic Alert level of Mt. Asama from Level 3 to Level 2. Caution must be exercised for falling rocks and pyroclastic flow within a 2km radius of the volcanic crater.

The current restricted access area is covered by the 2 kilometer-radius concentric circles on this map.

Please follow the instructions of local authorities and refrain from entering dangerous areas.

To Non-Hikers

The area beyond Mt. Asama is unaffected by the eruption and sightseeing facilities are operating as usual.

Due to the eruption, access to the area within a 2km radius of the volcanic crater has been restricted and trailheads are closed; however, sightseeing facilities and public transportation around Mt. Asama, such as Komoro City, Miyota Town, Karuizawa Town, etc., are running normally. We look forward to welcoming you in the Saku region.
