A sodium-led simple thermal spring, lightly mineralized at 158.8 mg/kg of dissolved solids and gentle on the body. Its alkaline pH of 9.18 gives the slippery, beauty-water feel that softens the skin, placing it among the more alkaline waters of its class. It is served at a retro Showa-era public bathhouse known for a painted Mt. Fuji mural.
