A sodium-led chloride spring with a bicarbonate edge — sampled as 'Ouka-sen' at 37.5 °C from a powered well in Minami-Alps. Weakly alkaline (pH 7.8 at the source, 7.97 in the lab), it carries a light salty tang and a faint metallic note. Mineralization sits at a moderate 1,145 mg/kg, enough for the heat-retaining feel typical of chloride water while the bicarbonate component softens the touch.
