Mount Asama, Complex stratovolcano in Honshū, Japan.

Mount Asama rises 2,568 meters above sea level at the border between Gunma and Nagano prefectures, with two distinct craters within its volcanic structure.

The 1783 Tenmei eruption lasted three months, causing lahars that destroyed the village of Kanbara and resulted in over 1,600 deaths along the Agatsuma River.

Mount Asama appears as a significant location in Japan's first color film Carmen Comes Home and receives recognition in the Neon Genesis Evangelion anime series.

The Japan Meteorological Agency maintains constant monitoring stations around the volcano, implementing a five-level alert system to inform about potential volcanic hazards.

Scientists from the University of Tokyo utilize muon imaging technology to create detailed internal maps of Mount Asama's volcanic structure.
