Nishi Azabu Crossing Space Invaders

There are several "Space Invaders" part of a tile mosaic located on the northwest corner of Nishi-Azabu crossing. I photographed it last November but spotted probably several years ago. It's a cool little detail that makes an otherwise ordinary building interesting. The funny thing is it looks like the defense against space invaders is bug spray.
