Mount Oakan

Mount Oakan rises approximately 1,370 meters above sea level and displays three distinct explosion craters at its summit. The stratovolcano sits within a national park in eastern Hokkaido and is composed largely of andesite.

The volcano formed during the Late Pleistocene through repeated lava flows. This activity created the pumice deposits that remain visible in the surrounding region.

Local people see this mountain and its neighbor across Lake Akan as two sides of the same natural power. This view shapes how visitors experience the landscape as a unified whole.

Hiking trails lead to viewpoints that offer wide views of the volcanic landscape, with rest areas and information stations placed along the routes. The paths require moderate fitness and are clearly marked.

A fumarole sits approximately 800 meters up the mountainside and demonstrates that volcanic activity continues today. This visible steam vent reminds visitors that the mountain remains geologically alive.
