A great deal of craftsmanship goes into every food replica, because they must look identical to the represented dishes, and there are even specialized competitions for making sampuru.
These high quality food replicas are products unique to Japan, and an elaborate restaurant window, displaying sophisticated sampuru, is probably one of the many images defining Japan.
