Nagisa no Yu is the only bathing facility in the Kami-Tsushima district, a plain day-use onsen next to Miuda Beach. The indoor bath has two tubs, a jet bath and a plain hot one, with a small utaseyu (打たせ湯) falling-water corner, and it looks out through big windows onto the sea. There's a sauna and a small cold bath too, plus a seasonal outdoor bath, though several recent reviews found it closed for weather or maintenance. The water has a soft, slightly slick feel that a few reviewers say leaves the skin smooth. It opened in 2004, run by a local development corporation, as a bath mainly for residents, and a Toyoko Inn now sits right next door. Beyond the baths there's just a tatami rest room and massage chairs, nothing more.
