Kanagawa Fujisawa City
"Enoshima Island Spa" is a resort-style hot spring facility in a prime location on Enoshima Island in Fujisawa, Kanagawa Prefecture. The natural hot spring, Fuji Kaiyu, springs from 1,500 m underground and offers a sweeping view of Mt. Fuji across Sagami Bay, creating an open, relaxing bathing experience. The sauna is a full-fledged dry sauna, and cooling down afterward in the cold plunge bath, Seisen, is exceptional. The swimsuit-required spa area features a wide variety of facilities, including an infinity pool that feels as if it is connected to the sea and a cave area, allowing couples and families to spend blissful moments surrounded by Enoshima's natural beauty.
