Mt. Asahi (朝日岳, 1945m) straddles Minakami Town in Gunma and Minami-Uonuma City in Niigata. Part of the Tanigawa Mountain Range, it is listed among the Kanto Hyakumeizan, Nihon Sanbyakumeizan, and Gunma Hyakumeizan. The sharp ridgeline and sweeping views are characteristic of the dramatic Tanigawa peaks.
The trailhead at Doaibashi is accessible on foot from JR Doai Station (10 min walk), or by Kan-Etsu Kotsu bus from Minakami Station or Jomo-Kogen Station.
