Mount Asahi

Mount Asahi is an active volcano in Daisetsuzan National Park standing at approximately 2,290 meters and ranking among Hokkaido's highest peaks. Fumaroles and hot springs dot the slopes, revealing ongoing geothermal activity beneath the mountain.

The volcano formed as part of the Daisetsuzan volcanic complex and experienced its most recent recorded eruption in 1739. Volcanic activity here extends back thousands of years to approximately 3200 BC.

Local indigenous traditions hold this summit as a sacred place where spirits are believed to dwell among the volcanic slopes. Visitors walking the trails encounter signs of this spiritual connection woven into the landscape.

A ropeway system transports visitors to higher elevations during warmer months, significantly reducing hiking time. The best season for trail exploration is June through October when snow and ice do not obstruct the paths.

Rare optical phenomena such as diamond dust and sun pillars appear in the thin mountain air during winter months. Alongside these wintry displays, alpine plants flourish on the slopes during warmer months, creating a striking contrast between seasons.
