Minami-Omuro-koya is a classic Southern Alps mountain hut + designated campsite sitting in a sheltered forest basin on the approach to Houō Sanzan. Despite being on a ridgeline route, it’s famously well supplied with water, with a stream running beside the hut—so it feels calmer and “softer” than many exposed ridge huts.

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.
