Kusatsu Onsen (草津温泉) is a hot spring resort located in Gunma Prefecture, Japan, northwest of Tokyo. It is a popular tourist destination. There are 13 public baths at Kusatsu Onsen. The small bathhouses that are free for both town residents and tourists are managed by the townspeople themselves.[1] The source of its hot water is nearby Mount Kusatsu-Shirane and the appearance of the waters range from cloudy to clear, because the sources of the water that the baths rely upon are different.[2] | ||||||
