Jet BathAbout
SPA&HOTEL Nagomi is a spa and hotel in Ota City, Tokyo, built around a natural black hot-spring source known locally as kuroyu. The indoor bath uses the dark mineral water straight from the source, and a second bathing area opens to natural light and air. There's also a cold plunge and a dry sauna, plus a stone-bed sauna using kiyoseki stone brought from a mine in Gunma. Family bath rooms let you soak in the same kuroyu water in private, either as part of an overnight stay or as a timed day rental. The spa also has a jet bath and a mist steam sauna in the women's bathing area, and a restaurant serving a mixed Japanese, Western and Chinese menu. Day visitors are welcome alongside hotel guests.
