Mt. Tanigawadake (1,977 m) is a part of the Mikuni Mountain Range in the border of Minakami Town in Gunma Prefecture and Yuzawa Town in Niigata Prefecture. It is in the center of the peaks of Tanigawa mountains, which start from Shimizu Pass, Mt. Shigekuradake and Mt. Ichinokuradake to Mt. Mantaro, Mt. Tairappyo and Mikuni Pass. Counted as one of Japan’s 100 Fine Mountains, Mt. Tanigawadake is a beautiful mountain but at the same time it is one of the most difficult mountains in Japan.

Mt. Tanigawadake has two peaks. One is Okinomimi Peak and the other is Tomanomimi Peak. Due to its geographical features, the seasonal wind from the northwest causes heavy snow in winter, while from early through mid summer, the mountain is covered with alpine flowers. In September, when leaves of Japanese rowan trees near the summit turn red, the foliage season approaches the mountain. During the foliage season in October, the mountain is visited much more climbers than in summer.
