Hot springs in Higashi

A wild natural hot spring on the volcanic island of Iojima in Mishima Village, Kagoshima Prefecture, reachable only by ferry from Kagoshima Port. Three open-air baths sit amid natural rock formations, open 24 hours with free admission. The water is strongly acidic and takes on a striking green color from natural mineral activity. Volcanic steam drifts overhead. There are no facilities beyond the baths themselves.
