A sodium-led chloride-bicarbonate blend drawn from three wells. The wellhead runs at a striking 75.5 °C — among Japan's hottest natural sources — and the water carries 11.1 g/kg of dissolved solids, putting it in hypertonic, ocean-strong territory with a clear salty tang. Bicarbonate softness layers in, and 89 mg/kg of metasilicic acid leaves a faint silky film on the skin, alongside the unmistakable whiff of hydrogen sulfide.
