About Saito Onsen
Located in Saito City, known for the Saitobaru Kofun Cluster, Saito Onsen prides itself on a natural hot spring of sodium bicarbonate spring water emerging from 1,000 m underground. The water feels remarkably slippery and silky, leaving skin smooth after bathing. The sauna is a spacious far-infrared dry sauna for about 20 people, set to 85°C–90°C but with very high power that delivers an intense, strong-style heat. After the sauna, guests can head to a generously sized cold plunge bath fed with abundant groundwater. This large super sento also offers a wide outdoor area and open-air relaxation space, as well as a variety of baths such as a waterfall bath, reclining bath, and more, ensuring a very satisfying experience.
