Nakanogo Onsen Yasuragi no Yu is located in Nakanogo, on Hachijojima Island, Tokyo Prefecture, part of the Izu archipelago in the Pacific. Sodium-chloride water reaches 42°C, shared between an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — In Nakanogo, one of the two main settlements of volcanic Hachijojima island in the Pacific south of Tokyo, Yasuragi no Yu offers peaceful relaxation in a community that was historically used as an exile destination — figures from Kojiki mythology to Edo-period scholars were sent to this green subtropical island; the spa provides warm refuge from the island's frequent Pacific storms.
