Izumo Heisei Onsen (Izumo Hoyo Center) is located in Izumo, Shimane Prefecture, Japan. Its sodium-chloride water reaches about 41°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Named for the Heisei era (1989-2019), Izumo Heisei Onsen combines community recuperation (hoyo) with mineral spring bathing in the city of Izumo Taisha — Japan's most spiritually charged Shinto shrine; the spa serves pilgrims and locals alike in a city where the mythological age (Kamiyo) feels present in every stone and cedar tree.
