Rakuyo, in Hakusan (Ishikawa prefecture), offers sodium-chloride water heated to 41°C. Bathers can move between an indoor bath, an outdoor rotenburo bath, and a sauna at this onsen set near the Meoto Iwa rocks.
Insider tip — Rakuyo at Meoto Iwa Onsen serves the foothills of Hakusan City where the husband-and-wife rock formation rises from the paddy fields as a landmark of the ancient pilgrimage approach to Hakusan Shrine. Meoto Iwa paired-rock formations are considered sacred throughout Japan as symbols of conjugal devotion — the most famous pair stands at Futami on Ise Bay — and their presence in the Hakusan foothills marks this spring as part of the sacred geography connecting the coastal plains to the mountain deity at the Hakusan volcanic summit.
