RiverAbout
A small hotel in the gorge along the Koshin River (庚申川) in Ashio, a former copper-mining town northwest of Nikko. The baths draw from Koshin-no-yu (庚申の湯), a clear, soft spring that feels smooth on the skin. Each side has an indoor bath, an open-air rock bath with mountain views, and a low-temperature sauna.
