Sukunahikona Onsen Garyu no Yu is located in Ōzu, Ehime prefecture, on the island of Shikoku. Its bicarbonate water reaches 41°C and is shared between an indoor bath and a rotenburo, plus a sauna.
Insider tip — Named for Sukunahikona no Mikoto, the Shinto deity of medicine and hot springs, this Ōzu spa carries deep spiritual meaning. Visit in summer when ukai cormorant fishing takes place on the Hiji River by torchlight just below the castle walls.
