Kamuro Onsen (Hot House), in Kaneyama, Yamagata Prefecture, heats sodium-chloride water to 42°C. An indoor bath, rotenburo and sauna are offered.
Insider tip — Kamuro Onsen serves Kaneyama-machi in the Mogami River valley of Yamagata, a town nationally celebrated for its commitment to architectural continuity where all new buildings follow traditional cedar construction principles established by the Kaneyama Design Code. The resulting streetscape of unified timber architecture and cedar-forested hillsides has made Kaneyama one of Japan most photographed heritage townscapes.
