Mixed source
Sodium Bicarbonate-Chloride spring
A blended sulfur-bearing sodium bicarbonate-chloride spring drawing on the Motoyu and Mine-no-yu wellheads. It emerges very hot at 83.2 °C — among Japan's hottest natural sources — carrying the unmistakable rotten-egg note of H2S and a faintly sulfurous edge on the tongue. Total sulfur sits at 5.4 mg/kg and bicarbonate makes up roughly two-thirds of the anion budget, layering jūsō-sen softness with a quiet salty finish over the dominant sulfur character.
