Mount Hiuchi (火打山, Hiuchi-yama) is one of the 100 Famous Japanese Mountains,[4] reaching the height of 2,462 m (8,077 ft).

It is situated in Japan's Kubiki Mountains in Niigata Prefecture.

It was specified for Jōshin'etsu Kōgen National Park on July 10, 1956,[5] but since has been absorbed by the Togakushi-Renzan National Park, which encompasses Mount Myōkō (妙高山 Myōkō-san) and Mount Niigata-Yake (新潟焼山 Niigata-Yakeyama).

This mountain is famous for the many alpine plants found above the tree line.

There are several climbing routes to the top of the mountain, principally from Sasagemine after the annual spring re-opening of the road.
