A sodium-calcium chloride spring served at Kounoyu, blended in a tank from four separate wells (Nos. 27, 28, 29 and 30). Neutral in pH and salty, it is a heat-retaining chloride water that keeps the body warm after the bath. It carries a generous 87 mg/kg of metasilicic acid, leaving a thin silica film for noticeably smoother skin, and is classified as a hypotonic high-temperature spring.

Onsen. Located a bit far from the station (the furthest of all seven Kinosaki onsen). Indoor bath is hot. Small outdoor bath with standard temperature. Water is clear, slight chlorine smell. Included in the hotel pass or in the 1,500 yen pass. Small towel 200 yen, large towel rental 300 yen per day (can be returned at any Kinosaki onsen). If you're not trying to visit all Kinosaki baths, you can skip this one in my opinion.
