Kusatsu in Gunma Prefecture is a very popular hot spring town with old world charm and lots of very hot water. The heart of the town is the 'hot water field' (Yubatake in Japanese). The hot water flows through rows of wooden chutes designed to expose the water to air and cool it. At night the 'hot water field' is lit up, as are the shops and restaurants around it. It looks beautiful and slightly surreal.
