An active volcano that you can see above Taisho Pond in Kamikochi. Yakedake literally means “burning mountain” and it still releases volcanic gases and smoke to this day. Taisho Pond was formed by an eruption on Mt. Yakedake in the early 1900s and evidence of the landslides it caused can be seen on the mountain.
Climbing Mt. Yakedake is possible even if you are not a seasoned hiker. It takes about 4 hours to climb to the peak (2,455 m) from Kamikochi and 2.5 hours to go descend to Nakanoyu Hot Springs or 3 hours to return back to Kamikochi. You can also do this in reverse, climbing up from the Nakanoyu trailhead instead.
