Hikarigaoka - Demo Garbage Truck

 I was walking back to my apartment and saw this small garbage truck with see through sides.

This is used to tell preschool kids about how the garbage system works and how to be safe around the trucks.  They have fake bags of garbage inside the truck.  The back opens up and the bags can be pushed out like in a real truck.  Then the trainers closed the back and threw bags into in and they were 'compacted' into the main storage area.
