Mixed source
Sodium Sulfate-Chloride spring
A sulfate-chloride spring led by sodium and calcium, drawn as the combined Shibu Onsen source blending Hira-no-yu, Yakushi-no-yu and Tobi-no-yu. Sulfate lends a settled, mineral body while the chloride content gives a salty, heat-retaining finish, all at a weakly acidic pH. At the wellhead the water is faintly yellow and clear with a slight iron taste.
