Yoshigaura Onsen is a hot spring town in Ishikawa, Japan. The water leaves the ground at 15.1–20°C, cool enough that the baths here are usually reheated. Officially the water is classed as chloride spring. Its sources put out around 12 litres a minute. 1 inns take visitors here.
Salty water. The salt leaves a thin film on the skin, so you stay warm well after leaving the bath.
