Hot Spring & Bath Information

Shonan Chigasaki Onsen

TypeNatural Hot Spring

This is a chloride strong saline hot spring that wells up from underground. With a high salt concentration, the water clings to the skin when soaked. Enjoy it in the indoor bath and the outdoor bath "Fujimi no Iwayu." The water has a salty film-like texture, offering very high heat retention. After bathing, you are less likely to feel chilled, and the relaxation from the core continues. On clear days, you can view Mount Fuji from the open-air bath, providing a superb sense of openness. It is also expected to have beautifying effects on the skin and is effective for joint pain and sensitivity to cold.
