The Asahi Mountain Range is located at the prefectural border of Yamagata and Niigata. With Mt. Daiasahidake (1870 m) as the main peak, the range includes 15 km of ridgelines including Mt. Nishiasahidake, Mt. Ryumon, and to Mt. Itodake as its main ridge. It is the largest mountain range in the Tohoku region and characterized with deep valleys cut into the sides. It is referred to as the Tohoku Alps, and loved by many hikers. Also, Mt. Daiasahidake is counted as one of “100 Most Famous Mountains in Japan” and is one of the most popular mountains among them.

Oe Town’s mountaineering club hosts two annual hiking tours, “Himesayuri Hike” when himesayuri comes in full bloom and the Autumn Foliage Hike during the autumnal foliage season when Japanese rowans and alpine cherries change their colors.

Asahi Military Road
In the Age of Provincial Wars, Naoe Kanetsugu, a vassal of the Uesugi family, was ordered to govern over Yonezawa and Shonai areas. However, in order to reach the Shonai area, he was forced to travel through the enemy land ruled by the Mogami family. He devised a way to fulfill his duty by secretly constructing the road to go over the Asahi Mountain Range from Yonezawa. Parts of the zigzag road still remain today on the mountainside of Mt. Itodake.
