Mount Asama
浅間山
An active volcano at 2,568 metres, the iconic backdrop of Karuizawa, best viewed from the outer rim peak Kurofuyama or other lookout points.
Mount Asama is one of Japan's most active volcanoes, constantly releasing white plumes of steam. Its graceful shape can be seen from almost everywhere in Karuizawa, and it is especially impressive when snow-capped in winter. Access to the summit crater is restricted depending on the current eruption warning level. Most visitors set out from Takayama Plateau in Komoro City or Kurumazaka Pass to climb Kurofuyama (2,404 metres), an outer-rim peak about four hours round trip, from where you can view the crater and the Maekake peaks. Always check the Japan Meteorological Agency's eruption warning level before you climb, and dress warmly. You can also see the mountain from the Hokuriku Shinkansen or from the area around Naka-Karuizawa.
