Nanashigure Onsen, attached to the Nishine seniors' rest home in Hachimantai, Iwate, offers sulfurous water at 44°C. An indoor bath, an outdoor rotenburo pool and a sauna round out the site.
Insider tip — Nanashigure Onsen, named for the Seven Rain Showers Mountain (Nanashigure-yama, 1,639m), serves the Nishine district of Hachimantai City where the volcanic highland produces the mist-laden weather that brings multiple rain showers in a single day. The sulfurous spring water rising from the Hachimantai volcanic system delivers the milky opaque water characteristic of active geothermal discharge, prized for its skin-healing mineral content across this extraordinary volcanic plateau.
