花山温泉 is a hot spring town in Wakayama, Japan. The water leaves the ground at 25.2°C, cool enough that the baths here are usually reheated. It measures pH 6.3 — close to neutral. Officially the water is classed as chloride spring, carbon dioxide spring and iron spring. Its sources put out around 118 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.
Fine bubbles cling to your skin. Rare in Japan, and usually cooler than other springs.
Turns reddish brown as the iron meets air. The water is clear at the source.
