Mount Shiragamon

白毛門

Minakami, Gunma · Elevation 1,720 m

Mount Shiragamon is a 1,720 m peak in Minakami Town, Tone District, Gunma, set across the Yubiso River directly opposite Mount Tanigawa and standing as the first summit on the Tanigawa horseshoe traverse. It lies within Jōshin'etsu-Kōgen National Park and along the Gunma Border-Ridge Trail; the east face is designated as a Gunma Prefectural Nature Conservation Area. The top serves as a grandstand for Tanigawa's east-face precipices — the Machiga, Ichinokurasawa, and Yu-no-sawa walls — and the long traverse from Doai Station via Mount Kasa to Mount Asahi takes roughly six hours, rating as an advanced climb. The peak features in Gunma Hyakumeizan and Kantō Hyakuzan.
