Kaike Onsen
Enjoy natural hot spring water in the spectacular large bath “Umi no Yu,” located 27 m above ground on the top floor. This chloride spring contains abundant salt from the bounty of the sea, and is renowned as a beautifying bath that helps smooth the skin while providing excellent heat retention and moisturizing effects. 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融け込むように浮かんでいるかのように, blending into the vast expanse of the Sea of Japan.
