Last Thursday when I was walking in Shibuya with Alex I stumbled upon Love Hotels after Love Hotels. Apparently these Love hotels (Sex Hotels) do not even have employees, but you buy rent rooms through a vending machine or some other self serve method.
Well Alex thinks this was the entrance to one (I thought it was a restaurant). We walked by it when we noticed that it had a waterfall and we wondered how people could get in without getting wet. It had a motion sensor that stopped the waterfall when you got close enough. Here is the video (check out my Mickey Mouse ear muffs):
