Pearl Star Hotel Atami

A rooftop onsen on the twelfth floor, spring-fed and infinity-edged, with the Pacific rolling out below. This Michelin Selected hotel in Atami keeps everything else equally calm: rooms done in a modern take on classic Japanese style, paper screens and understated finishes, none of the maximalist resort theatre you'd find elsewhere. Five restaurants and bars means you can probably avoid leaving, which, given the views, is the idea.
