It is also one of the 100 most famous mountains in Japan, and in the alpine zone beyond the forest limit, there are even grouse. From the summit, you can view the Yari-Hotaka mountain range, and if you follow the ridge to the south, you can reach Mt.Chōga! Chōgatake can also be reached by following the ridge line to the south!

Mountain Climbing Experience
Early October was supposed to be the best season to see the autumn leaves in full bloom in a normal year, but in 2023, the weather cooled down rapidly after a heat wave, and the difference in temperature did not allow the leaves to change color properly…. Therefore, we were not able to fully enjoy the autumn foliage, but thanks to the snow, we were able to enjoy the odd sight of autumn leaves and snowy mountains from the summit of the mountain! There are only a limited number of one-day hikes in the Northern Alps, so we encourage everyone to try climbing them!

It is nice to have a stream.
After an hour and a half of climbing, the steepness of the climb increases….
However! On the left, you can see beautifully colored trees!

We are gradually approaching the summit while enjoying the autumn leaves and open scenery!
Only 800 meters to go…!
08:00 Two and a half hours have passed since we started climbing.
We arrived at Jouen Norigoe! Suddenly the wind picked up and it became very cold, so I quickly put on my jacket!
The Jouen Hut and the Yari-Hotaka mountain range towering behind it are beautiful again!
