Steam SaunaAbout
This resort hotel sits on the small island of Senagajima, right next to the runway at Naha airport, and its bathing water is drawn from a thousand meters under the island. The main bath is a large open-air rotenburo with sea views: from the standing bath you can watch planes land, catch the sunset over the Kerama Islands, and see a clear night sky. There is also an indoor bath, a loyly sauna and a mist sauna with a salt that changes daily on each side, and a cold plunge to cool off afterward. Some of the rooms that mix Japanese and Western styles have their own private open-air bath. Day-use bathing is available, and there is an ocean-facing restaurant serving Okinawan dishes.
