A sodium chloride spring, pumped from a drilled well at Okita in Shirakawa village. At the wellhead the water carries a faint yellow-brown tint while staying clear, with a slight bitterness and a whisper of hydrogen sulfide behind it. Weakly alkaline and soft on the skin, it holds 3,132 mg/kg of dissolved solids — moderately mineralized, with noticeable body. Chloride water of this kind is valued for the way it holds heat, so the warmth tends to linger well after the bath.
