Choujou-Sansou
頂上山荘
2,867 m · Miyada, Nagano · 0.2 km from the summit of Mt. Nakadake
Mountain hut at about 2,870m in the saddle between Kiso-Komagatake and Nakadake in the Central Alps, administratively in Miyada Village, Nagano. Miyada Kanko Kaihatsu runs it alongside Hokken Sanso and Tengu-so. It lies beyond Norikoshi-jodo and Nakadake from Senjojiki Station on the Komagatake Ropeway, and its draw is the quiet setting just below the summit of Kiso-Komagatake. The flat ground in front is one of the range's few designated campsites, taking about 100 tents, and komakusa and the endemic Komausuyukiso bloom nearby. The hut has a dining room, shop and three guest rooms on the ground floor plus seven upstairs, and serves light meals such as curry rice and pork soup. Open flames and self-catering are not permitted indoors.
2026: open July 10–October 5 · reservation required · sleeps 50
