Shirato Falls - Waterfall of White Thread

No river feeds into Shirato Falls near Karuizawa, instead they are fed by ground water from the base of the volcanic Mt Asama.  The falls are in two stages, with the top falls being 3m high but in a curve of 70m.  They looked great steaming on winters day, I don't think I have ever visited a waterfall in the snow before.  The falls, their locattion and the walk to them would be spectacular with the lush greenness of summer of the colours of autumn in the surrounding larch trees.
