Nikko-Shirane volcano is a small andesitic volcano located NW of scenic Lake Chuzenji in Nikko National Park. The volcano contains 4 lava domes sitting on top of a shield volcano (Keizuka-yama).
All historical eruptions, recorded during the 17th-20th centuries, were phreatic explosions from Shirane-san, the youngest lava dome.
Keizuka-yama shield volcano is composed of viscous lava flows with prominent levees. The geometry of these flows created scenic lakes to the north of the volcano.
