A hot 53 °C blended source from Ito Onsen's Mizuochi cooperative, classified as a simple thermal spring with a total mineralization of 0.879 g/kg sitting just under the chloride-spring threshold. Sodium leads the cation profile while chloride and sulfate share the anion side almost evenly. Weakly alkaline at the wellhead (pH 8.4), it falls in the soft Japanese 'beauty-water' family — the water is nearly colorless and transparent, with no taste or odor, and a modest 57 mg/kg of metasilicic acid leaving skin smooth without the heaviness of a fully mineralized chloride bath.
