Onsen Hoyokan (Yu no Se), also in Tsu, Mie Prefecture, heats sodium-chloride water to 41°C, with an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Yu no Se, the thermal waterfall spring, serves the western hills of Tsu City overlooking the Ise Bay coastal plain where the volcanic geology of the Kii Peninsula delivers geothermal heat through ancient fault lines. Tsu is equidistant between the Ise Grand Shrine and Yoshino sacred mountain — Japan two most revered religious destinations — making the city a historical crossroads of pilgrimage traffic whose influence permeated local culture with centuries of sacred hospitality and fine craft production.
