Takahata Onsen / Yu no Honkan, in Gujō, Gifu Prefecture, taps a sodium-chloride spring at 41°C. The bathhouse combines an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Yu no Honkan, the main spring building at Takahata, serves the southern Gujō community near the confluence of the Nagara and Yoshida rivers where mountain gorge gives way to Mino basin. The Takahata area preserves traditions of Hon-mino-shi handmade washi paper production using Nagara River water for the sheet-formation process, a craft recognized by UNESCO as an Intangible Cultural Heritage of Humanity.
