Mount Tomuraushi

Mount Tomuraushi is an active volcano in Daisetsuzan National Park that rises to 2,141 meters. The trails pass through varied alpine vegetation and rock formations shaped by its volcanic origins.

This mountain formed during the Pleistocene and Holocene epochs, creating a landscape of mafic rock formations. Its geological evolution continues to shape the terrain and character visitors experience today.

The Ainu people named this mountain Tomuraushi, referring to a place abundant with flowers or marked by water stains. This naming reveals how indigenous inhabitants recognized the seasonal changes and natural features visible on the slopes.

The safest climbing window is from July through September, though conditions vary. Access points are available from the nearby towns of Biei and Shintoku for different hiking routes.

Beneath the summit, hot springs and sulfur vents reveal ongoing volcanic activity within the mountain. These thermal features make it a natural laboratory for observing geothermal processes still at work.
