Daizumori-yama is a mountain on the borders of Oe Town and Nishikawa Town near the Oisawa Tunnel. The trail is relatively easy even for beginners, and along the trail there are beech and Erman’s birch trees, as well as Moriaogaeru frogs, hawk eagles, and serows. In spring there is fresh greenery, bamboo shoots, Zenmai (ostrich fern), and other mountain vegetables. In autumn, many families and friends go out to take in all the leaves. Also, there is the Jintsukyo gorge, the Okuoe Yanagawa Onsen, and Kodera Kosen hot springs nearby. 

Daizumori-yama Trail (30 minutes one-way)

There is an 800m trail essentially straight to the summit from the base of the mountain. At the summit there is a 10m high lookout made of Nishiyama cedar from where you can get 360° views out to the Asahi Mountain Range, Gassan, Murayama Hayama, Zao-san, and more. There is also a carillon bell with a nice sound, so be sure to play it when you go.
