The top floor features the observation open-air baths Fuji no Yu and Ashitaka no Yu. Their greatest appeal is the overwhelming panoramic view of Mt. Fuji rising beyond Suruga Bay. Bathing while watching Mt. Fuji change its expression with the time of day and the seasons, or the fishing lights glittering at night, is truly exceptional. The gentle simple hot spring, with little irritation to the skin, soothes travel fatigue and neuralgia in a slow, soothing way.

A reservation-only private bath popular with couples, families, and guests with small children. In a space where privacy is fully secured, you can enjoy high-quality simple hot spring water at your own pace without worrying about other people.
