A high-quality private hot spring with abundant skin-beautifying ingredients. In the main building's first-floor Hana no Yu and Nagisa no Yu, you can enjoy lavish free-flowing spring water only at night. From the large public bath on the second floor of Yubinkan, you can take in sweeping panoramic views of the majestic Sea of Japan and the beautiful garden right in front of you. The water feels smooth and pleasant, and the excellent heat retention and skin-beautifying effects unique to a seaside hot spring gently nourish both body and mind from within.

A functional bath infused with tourmaline, said to emit negative ions and far-infrared rays, with the fragrance of hinoki cypress throughout. The pleasant hinoki scent and warmth, like forest bathing, gently soothe the five senses and guide both body and mind into a deep state of relaxation.
