Mt. Daibosatsurei, Mt. Koganezawa (Koganezawa-yama) and Mt. Ushiokuno-gangaharasuri (Ushiokuno-gangaharasuri-yama) are a series of mountains running south to north, located in the northeastern part of Yamanashi Prefecture, and are a part of the Daibosatsu Peaks. Located inside the Chichibu Tama Kai National Park, Mt. Daibosatsurei is also selected as one of Japan’s 100 most famous mountains. This course introduces a scenic hiking route with a great view of Mt. Fuji, starting from Kaminikkawa-toge Pass to Mt. Daibosatsurei in the north, then proceeds southward on the ridgeline to Yamato Tenmokuzan Onsen (hot spring).
