Mount Mantarō

万太郎山

Minakami, Gunma · Elevation 1,954 m

Mount Mantarō is a 1,954 m peak on the border between Minakami Town in Gunma and Yuzawa Town in Niigata, set near the middle of the Tanigawa range — the Mikuni Mountains — half-way along the Jōetsu border ridge between Mount Tanigawa and Mount Tairappyō, within Jōshin'etsu-Kōgen National Park. As the spine dividing the Pacific and Sea of Japan watersheds, the summit is famously fickle. The Gosaku-Shindō trail cut by Yuzawa local Takanami Gosaku from 1953 climbs from Tsuchitaru on the Niigata side in about four hours, and the peak also serves as a key waypoint on the long traverse from the Tanigawa Kata-no-koya hut or Tairappyō. An unstaffed emergency shelter, the Daishōji Hut, sits just below the summit. The peak features in the Gunma Border-Ridge Trail, Niigata 100 Meizan, and Echigo Hyakuzan.
