About
Yumoto Sugishima is a small ryokan of 13 rooms in Itadori, deep in Gifu's Oku-Mino mountains, built around a wealthy farmer's house relocated here from the Edo era. The indoor bath keeps two tubs side by side: one gently heated with a hinoki scent, one cooler and left untouched, its water straight from the source with a light whiff of sulfur, kept flowing without reheating. Up a bamboo grove behind the main building are two reservable open-air baths named after the Myojin-yama (明神山) and Takaga-yama (高賀山) peaks. Guest rooms vary, some with an irori hearth, some with their own open-air bath, and the kitchen serves river fish raised on site alongside spring greens, autumn mushrooms, and winter boar hot pot. The inn belongs to the Association of Secluded Hot Spring Inns (日本秘湯を守る会), and day visitors can pair a soak with the lunch kaiseki.
