Sayonara Jupiter

Bye-Bye Jupiter (さよならジュピター, Sayonara Jupitā; lit. Goodbye Jupiter) is a 1984 Japanese science fiction film directed by Sakyo Komatsu and Koji Hashimoto and co-produced and written by Komatsu. An early draft of the film's story was novelized by Komatsu two years prior to its release as Sayonara Jupiter, which won the 1983 Seiun Award. Akihiko Hirata made his final film appearance in the film.

Bye-Bye Jupiter is notable as the first Japanese film ever to use computer-generated imagery for visual effects.
