Mount Motoshirane

Mount Motoshirane is an active volcano in the Kusatsu-Shirane volcanic group that rises to roughly 2,171 meters with steep slopes and varied geological features. The mountain displays typical characteristics of an active volcanic zone with visible changes in its structure.

A major eruption happened here in 2018 that sent ash traveling far across the region and released large amounts of rock and ash. This event demonstrated how active and powerful the volcano remains.

Local people see this peak as a spiritual presence that shapes stories and art in the region. Visitors notice how the mountain influences daily life and local traditions here.

Hikers can explore this peak along marked trails during summer months, though they should watch for local conditions and volcanic activity. Visitors planning a trek should gather current information and pay attention to regional safety measures.

Below the mountain lies a complex system of hot springs and underground water reservoirs that shape how it erupts. This hidden activity beneath the surface makes the peak a remarkably dynamic place.
