• There was an additional dream sequence that is missing in all versions subsequent to the original Japanese theatrical release. It is set in a grim future world where Ataru is an elderly homeless man. Unlike the other dreams, this one is played seriously. The missing sequence supposedly occurs after the one where Ataru gets hit on the head with a mallet by Mujaki, resulting in an abrupt cut in the film.
  • The US dub of the film changes Ten's gender to a girl. This is shown in Mendo's dialogue "we can exclude Ten and her pet piglet" instead of "his pet piglet".
  • Early DVD/VHS versions of the movie in the US omitted the very last part of the ending sequence, where the camera pulls away from Tomobiki slowly, replacing it with the DVD and dub credits. The new 2004 pressing restores the short sequence.
