An iron-bearing sodium chloride strong-salt spring drawn from Arima's Urawari source. At 37.6 g/kg dissolved solids it is hypersaline — exceeding ocean salinity and leaving a thick mineral coating on the skin. It is iron-rich (67 mg/kg) and oxidizes reddish-brown on contact with air, and with a wellhead temperature above 100 °C it ranks among Japan's hottest natural sources.
