There are many different kinds of hot springs in Japan, and they vary from place to place and from region to region as well. Where I live, in Kyushu, the 'clear' hot spring is predominant, though there are certainly many exceptions as well. Deep in the earth, the water is heated by volcanic magma, as it rises it is filtered through layers of rock which not only lower the temperature of the hot spring, but remove most of its original mineral content as well. The result is a warm, nearly odorless 'mineral water.' It can be so tepid in fact that hot spring resort proprietors must heat the water by artificial means to make it pleasant for bathing.
