Suirendo Onsen is located in Ena, Gifu Prefecture. Bicarbonate water flows at 40°C here, filling both an indoor bath and an outdoor rotenburo, with a sauna rounding out the facility.
Insider tip — Suirendo Onsen occupies a forested valley in Ena City along the Kiso River gorge in southern Gifu, where bicarbonate-rich spring water emerges from the ancient sedimentary rock formations of the Chuo Alps foothills. The silky, slightly alkaline water is celebrated locally for its skin-softening qualities and the gentle, effervescent sensation that distinguishes true bicarbonate springs. The surrounding Suirendo gorge is one of Gifu's hidden scenic treasures, with sheer rock faces and emerald river pools visible from the outdoor bath. Autumn evenings here, with the mist rising off the river and the mineral warmth enveloping the body, are genuinely unforgettable.
