Roten-buro (outdoor onsen)... Sexy time in the great outdoors

Lake Kussharo is also famous for its outdoor onsen dotted around the lake called roten-buro. These are free public hot springs on the lake's edge. Some are pretty ordinary but some, like the one pictured below that we went and nuded up for, are pretty sweet. The hot tub was quite hot in contrast to the chilly breeze that was blowing. We had to walk through the snow to get to the onsen and the honking of the geese was like symphonic mood music.
If nudity offends don't watch the video.
