Tucked away in Minami-Awaji, Hyogo, Uzushio Onsen; Yutorikku draws on naturally heated thermal sodium-chloride water at 40°C. Visitors will find an indoor bath, rotenburo and sauna.
Insider tip — 'Uzushio' (whirlpool) Onsen 'Yutorikku' (leisurely) in Minami-Awaji, southern Awaji Island. The famous Naruto whirlpools churn just 5 km south in the Naruto Strait — a natural spectacle viewable from sightseeing boats. The island's outstanding onion, seabream, and beef cuisine complements this relaxed hot spring stop.
