Yakushi-sawa-goya (薬師沢小屋)

Yakushi-sawa-goya is a classic deep-valley stage hut in the Northern Japanese Alps, set at the dramatic confluence of the Kurobe headwaters and Yakushi-sawa. It’s best understood as strategic infrastructure: a key overnight node linking major interior hubs such as Taro-daira-goya and Kumono-daira-sanso, used by traverse parties moving through one of Japan’s most committing backcountry corridors.
