The Azuma Kofuji cone with its 300-m-wide crater is one of many volcanic features of the Azumayama complex. This volcano group consists of a cluster of cones and lava domes. Volcanic activity has migrated to the E, with the Higashi-Azuma volcano group being the youngest. This photo was taken from the NW on the flanks of Issaikyoyama, which has been the site of historical eruptions (mostly small phreatic explosions).
