Impressive, well-crafted, Japanese Shinagami motorized toy doll

Any toy designer or graphics designer should have been highly impressed by the movie's prop, creepy, Japanese Shinagami toy doll. I wonder who were the skilled prop makers? The creepy motorized toy doll looked like it came from a toy manufacturer. I was highly impressed. I wouldn't want to own that doll but I'm certain there would be a lot of takers.
