Half Pipe Don Quijote Roppongi

Constructed on the roof of the 8-story building of the Don Quijote store in Roppongi, Tokyo, the half pipe roller coaster photographed here was never used.

The reason is not clear, some say that the neighbors complained about the noise, others say that the building, although capable to sustain the weight, had some problems with the forces created by the roller coaster.
