Soaking in this outdoor bath right on the seashore is a unique experience that you won’t find anywhere else! The best time to enjoy it is at sunset, when the sky gradually takes on a reddish tinge and the crimson evening sun slowly sinks below the horizon. Gazing at this spectacular sight while soaking in the bath is the ultimate in luxury. Since the seaside outdoor bath is only open to day visitors until 4:00 p.m., when the sun is still high in the sky, an overnight stay is recommended to fully enjoy this luxury. The dinner with plenty of locally caught seafood is another draw.

In addition to the gourd-shaped outdoor bath, which is mixed sex, there is also a round outdoor bath for women only. When including the indoor baths for men and women respectively, there are four baths in total, all of them 100% natural hot-spring baths with water flowing fresh and untreated from the source.

The name of the hot spring comes from the Japanese word furofushi meaning “immortality,” derived from the local saying that “anyone who enjoys the benefits of these waters will never grow old or sick.” Due to oxidation of its iron content, the water is such a dark reddish brown that the bottom is not visible. Since this distinctively colored water is so rich in iron and salt, it will warm you from the inside out, keeping you from feeling chilly after bathing.
