A sodium-led bicarbonate spring with sulfate and chloride layered in, drawn very hot at 72.8 °C — among Japan's hottest natural sources. The pH is neutral so the touch is unforced, but an unusually high 348 mg/kg of metasilicic acid leaves the kind of silica film associated with Japan's beauty-water family. At the source the water carries a very faint yellow-brown tint and a touch of turbidity, giving it visible body.
