About the Mountain

  Mt. Asama is a prominent active volcano known around the world, and loved by local people as the symbol of the Saku area. It is 2,568m (8,425ft) above sea level, and was chosen as one of 100 Famous Japanese Mountains.

  There are two trekking trails on the mountain: the Kurofu Course (enter from Kuruma-zaka Pass), and Kazankan Volcano Visitor Center Course (enter from Hotel Tengu Onsen Asama Sanso). Please enjoy magnificent views of the active volcano from either trail. Shuttle buses are available for circuit trekking connecting both courses.
