Yumekaiyu Awajishima sits on the Ohama coast in Sumoto and has two separate spa zones. The main building's sixth-floor spa holds large communal baths (Izumi and Hibiki) where floor-to-ceiling windows open onto the hillside woods, plus a reclining bath and sauna. The separate 海音の森 (Umine no Mori) spa has an open-air rotenburo where you can hear the sea, a seasonal herb bath, and two private baths for exclusive use. The main building's private rotenburo, Yumemi (夢海), looks out over the beach. The spring water from Sumoto Onsen has a gentle, smooth feel on the skin. Men's and women's assignments across the communal baths rotate between morning and evening.
