Kaike Onsen
A warmly retaining bath filled with sodium chloride spring water from Kaike Onsen. Its mild, salty texture gently envelops the skin, and after bathing, a veil of hot spring minerals remains, helping you stay warm even on winter walks. The indoor bath and open-air bath on the first floor have a pleasantly moderate water temperature, while the large cypress barrel tub offers an openness that makes you want to soak for a long time. The highlight is the second-floor observation bath, where you can luxuriate in the rough waves of the Sea of Japan and the night illumination all to yourself while soaking in the water.
