| Mount Kusatsu-Shirane (草津白根山, Kusatsu Shirane-san) is a 2,165 m (7,103 ft) active stratovolcano in Kusatsu, Gunma, Japan.[2] It is called Kusatsu Shirane to differentiate it from the Mount Nikkō-Shirane on the other side of Gunma Prefecture. The summit of Kusatsu-Shirane volcano, located immediately north of Asama volcano, consists of a series of overlapping pyroclastic cones and three crater lakes. The largest of these is Yu-gama, an acidic emerald green lake with rafts of yellow sulfur sometimes seen floating on its surface.[3][4] |
