Kanazawa Onsen, located in Kitaakita, Akita Prefecture, offers sodium-chloride water at 42°C. The facility provides an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Kanazawa Onsen in Kitaakita should not be confused with the famous Kanazawa of Ishikawa — this is a quiet mountain spring in northern Akita whose Ani River valley borders the Shirakami Sanchi, a UNESCO World Heritage wilderness of primary beech forest stretching across the Akita-Aomori border. The ancient beech ecosystem here filters some of Japan purest snowmelt into the river systems that feed these highland springs.
