A spa resort hotel standing inside Mihama American Village in Chatan, Okinawa. Its Chatan Onsen - weakly alkaline simple spring water drawn from 1,400 metres down - fills the top-floor (8F) panoramic large baths, which gaze out over the East China Sea and Sunset Beach. The men's side has a high-temperature sauna and cold bath; the women's side a mist sauna and a warm 36-37°C bath. Day bathing runs mornings 6:00-10:00 and afternoons 15:00-25:00 (final entry 30 minutes before each close) at 1,500 yen for adults and 1,000 yen for children, with bath towel, face towel and amenities included. Sunset Beach is a 4-minute walk away, with free parking for 250 cars - a resort-style onsen stop between Okinawa sightseeing.
