Itamuro Onsen Nasu Tochigi

Itamuro Onsen Nasu Tochigi is located in Nakagawa Town in Tochigi Prefecture, in the gentle forested landscape of the Naka River valley south of the Nasu volcanic highlands — a quieter, more secluded thermal area away from the popular Nasu highland resorts, set in the cedar and broadleaf forests of the Tochigi hills that extend toward the Kanto Plain. The bicarbonate thermal waters of Itamuro are characterised by their clarity and smooth pH, producing the silky 'beauty water' quality that Japanese bathers particularly prize, and have been used by travellers resting on the Naka River road since at least the Edo Period. The surrounding landscape of Nakagawa's cedar forests, traditional washi paper production, and the Yoriishi scenic valley waterfalls creates an atmosphere of profound rural Tochigi tranquillity, making Itamuro one of the prefecture's most restfully authentic and least-touristed onsen experiences.
