A blended simple thermal water drawn from three Ito Onsen wells (Oka No. 173, Kamata No. 41, Oka No. 277) and mixed in an underground storage tank before being sent to the baths. Total dissolved solids sit at 696 mg/kg with a pH of 8.2 — weakly alkaline, gentle on the skin, and squarely in simple-spring territory. The wellhead is hot at 51 degrees Celsius and the water is cooled to the bathing range of 39 to 42 degrees before serving.
