Yakushi-dake-koya (薬師岳小屋)

Yakushi-dake-koya is a classic high-ridge mountain hut on Houō Sanzan (Yakushi-dake / Kannon-dake / Jizō-dake), positioned on the saddle between Yakushi-dake and Sunaharai-dake. It’s primarily a stage hut: a practical overnight to split long ridge days, time weather windows, and access the Houō ridgeline with better margins.
