Shichikama Onsen Yuraku-kan is a day-use hot spring bathhouse in the Shichikama Onsen area of Shinonsen. It has indoor and outdoor baths, making it an easy stop if you want the onsen experience without staying overnight.
It is less famous than nearby Yumura Onsen, which is part of the appeal. Come for a soak after walking the coast or visiting the town's smaller museums.
