The stratovolcano Akagi ( Jap. 赤城山 , Akagiyama ) is one of the major mountains in Gunma Prefecture in Japan . It is characterized by its long, gently sloping slopes. The highest point is 1828 m above sea level.
Akagi Nature Park is on the west side of the mountain . The Andesite volcano rises above the north end of the Kanto plain. The 3 × 4 km measuring, elliptical caldera contains several lava domes , which lie in a line oriented from northwest to southeast. Lake Ono is located in the northeast end of the caldera. The construction of the central crater began after the last major Plinian eruptions about 31,000 years ago. Historically, some eruptions were reported in the 9th century. However, reports of outbreaks in 1251 and 1938 must be considered uncertain.
