Nanno Onsen Suisho no Yu is located in Nanno, Gifu Prefecture. Its iron-rich water surfaces at 41°C, pH 6.3. Facilities include an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Suisho no Yu, Crystal Bath, offers iron-laden spring water in the fertile flatlands of Gifu Prefecture south of the Japan Alps. The characteristic amber tint of the water is a mark of its mineral richness, and bathers often emerge with a pleasant warmth that persists for hours. Surrounded by rice fields, the facility has a distinctly rural character that contrasts with its modern amenities. The open-air bath at dusk, with mountains silhouetted against a pastel sky, is the highlight of any visit.
