Kamigane Onsen is located in Sendai, Miyagi Prefecture. Its sulfurous water, with a pH of 6.5, emerges at 44°C (111°F). An indoor bath, an outdoor rotenburo bath and a sauna make up the facility.
Insider tip — Kamigane Onsen lies north of Sendai in Miyagi Prefecture, a coastal area with active volcanism feeding sulfurous springs. The milky-white water carries the characteristic hydrogen-sulfide aroma prized for skin-beautifying properties. Locals bring towels and linger in multiple pools of varying temperatures, following the traditional Japanese cascading soak ritual. The surrounding landscape of cedar-clad ridges and river valleys adds to the restorative experience.
