Fed by Ureshino Onsen's Spring No. 4-3, this is a sodium chloride-bicarbonate spring. The bicarbonate component lends a softness layered onto the salt, and at a weakly alkaline pH the water has the slippery feel of Japan's beauty-water family. The source emerges above 81 °C, ranking it among Japan's hottest natural springs; at the wellhead it is colorless, transparent and odorless.
