Foot BathAbout
Sachinoyu Onsen is a ryokan in Itamuro Onsen (板室温泉), a quiet hot-spring area inside Nikko National Park. Locals call it tsue wasure no yu (杖忘れの湯), "the cane-forgetting bath." Alongside an indoor bath, it has two outdoor baths that swap between the men's and women's sides day by day: Tsuna-no-yu (綱の湯), a rare standing bath where you hold a thick rope in deep water, and Otaki-no-yu (大滝の湯), built around a tall waterfall-style utaseyu (打たせ湯). The alkaline spring water is clear and essentially odorless, drawn straight from the source and kept flowing fresh. The inn is geared toward older guests and long-stay toji (湯治) visitors, and reviewers note genuinely attentive, personal service.
