Mt. Washiba (Washibadake, 鷲羽岳, 2,924 m) straddles the Toyama–Nagano prefectural border. One of the 100 Famous Mountains of Japan, it anchors the “Ura-Gin’za traverse” in the Northern Alps. From the summit, a 360° panorama opens to Mt. Yari, Mt. Hotaka, Mt. Suishō, and Mt. Kurobegorō. The view of Washiba Pond just below the summit, with Mt. Yari beyond, is one of the iconic scenes of the Northern Alps.
The shortest approach is JR Toyama → Toyama Chihō Railway Arimineguchi Station → Natsuyama Bus (Arimine Line) to Oritate. From Oritate, the summit is about 11 hours via Tarōdaira and Kumonodaira (standard 2-night plan). Alternative entry via Shin-Hotaka Onsen and Sugoroku Goya is also possible.
