Nakajima, Chigasaki, Kanagawa Prefecture
Shonan Resort Spa Ryusenji-no-Yu, Chigasaki
Best for adults who can set aside at least four hours for separate bathing and sauna areas, plus shared stone-spa rooms, manga, recliners, dining or desk space. It is a poor fit for a short two-hour stop, anyone relying on a tattoo-cover exception, or families with elementary-school children hoping to use the fifth floor.
