SeaAbout
Washu Blue Resort is a hotel in Shimotsui with onsen water from the local Washuzan-Fukiage spring. Its rooftop open-air bath, in the annex, sits about 110 meters above the sea and looks out over the Bisan Seto strait and the Seto Ohashi bridge. A separate indoor bath, the honey pearl bath, is reserved for overnight guests, and two suite categories come with their own private open-air bath. The baths are separate for men and women.
