A sodium-led iron-rich chloride spring classified as a strong-salt source, exceeding ocean salinity at 36.09 g/kg dissolved solids. It is rich in iron and oxidizes to a reddish-brown — the classic 'golden water' (kinsen) character of this district — leaving a thick mineral coating on the skin after bathing. Neutral pH and a generous 121 mg/kg of metasilicic acid round out a heavily mineralized water with real body.
