Kaike Onsen
TypeNatural Hot Spring
Natural hot spring water enjoyed at the spectacular large bath, Umi no Yu, located 27 m above ground on the top floor. This chloride spring contains abundant salt, a blessing of the sea, and is renowned as a skin-beautifying hot spring with excellent heat-retaining and moisturizing effects, while also leaving the skin smooth. Soaking in the open-air bath while listening to the gentle sound of the waves and feeling the sea breeze offers an overwhelming sense of openness, as if you were melting into and floating upon the vast expanse of the Sea of Japan.
