Hot springs in Kanzanji

A hot spring resort on the northwestern shore of Lake Hamana in Hamamatsu, Shizuoka Prefecture. The large salt lake is brackish where ocean meets fresh water, and the spring beneath it is a sodium-calcium chloride water with one of the highest salt concentrations of any onsen in Japan. The lake view from the outdoor baths, with Mount Fuji occasionally visible in the distance, is the defining feature of a stay here.
