Mt. Mamushi
マムシ岳
Ueno, Gunma · Elevation 1,308 m
Mamushi-dake is a 1,307 m peak in Ueno Village (Tano District, Gunma), featured in Nishi-Jōshū no Yama 120 and the variation-route guide Yabuiwa-damashii. The name refers to the snake-like, twisting form of its rocky ridge. With faint paths, friable rock, and exposed scrambling sections, it is regarded as one of the hardest peaks in the Nishi-Jōshū region — a variation route demanding map-reading skill, a helmet, and prior experience.
