Ureshinogensen Hyakunen Hot Spring is a day-use bathhouse in Ureshino, Saga, built on a spring with a hundred-year history. The operator says it is the only public bathhouse in Ureshino with its own hot-spring source. The water is smooth and faintly slick on the skin, in keeping with Ureshino's reputation as one of Japan's three great skin-beautifying hot springs. The shared indoor bath has a hotter tub and a cooler one, and six separately booked private baths vary in style: a stone-built room that opens to a semi-outdoor space, a hinoki-wood room, tatami-floored rooms, and a newer sauna-equipped room. A restaurant serves the local onsen yudofu (温泉湯豆腐), tofu simmered in the spring water, alongside a massage room and rest areas. The current building went up in 2016 on the site of the older Motoyu Onsen (元湯温泉) public bath.
