Yunoura Onsen Center is a hot spring in Ashikita, Kumamoto Prefecture, on the island of Kyushu, Japan. Its sodium-chloride thermal water sits around 39°C, with an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — 'Yunoura Onsen Center' (湯の浦 — hot spring cove) in Ashikita-cho on the southern Kumamoto coast, where forested mountains plunge steeply to the Yatsushiro Sea. Ashikita's rugged coastal landscape — the 'Cape Tsunagidon' sea cliffs, subtropical forests and hidden sea-coves — contrasts with the industrial Yatsushiro plain to the north. The onsen cove name evokes a sheltered thermal bay tucked into this dramatic coastal geography.
