It's the 22nd Century (2125 AD), and mankind's population has exponentially expanded beyond Earth's carrying capacity. Therefore, humans now live throughout the Solar System and the total population has gone well over 18 billion. As a result, there's a severe energy crisis for planets further out from the sun and plans to turn Jupiter into a second sun have been set into motion. However, markings are found on Mars that indicates that alien life lives in Jupiter and the J.S. Project (Jupiter Solarization Project) is put on hold.

Meanwhile, rogue members of the radical environmentalist group Jupiter Church attempt to sabotage the J.S. Project. In an ironic twist of fate, the head engineer of the J.S. Project, Eiji Honda, discovers that his ex-lover Maria is one of the radicals planning on sabotaging the project. At the same time, a satellite carrying two crew members is destroyed by a black hole heading straight to the center of the Solar System. This black hole could destroy humanity in one fell swoop once it collides into the sun. However, Jupiter is near the black hole's path. The engineers of the J.S. Project decide to change their plan and shoot Jupiter into the black hole, thereby altering the hole's path and potentially save the galaxy's inhabitants. However, time is short....



Bye Bye Jupiter was released in Japan on 17 March 1984, distributed by Toho.[1] The film was never released theatrically in the United States. It was released on DVD by Discotek Media in both an English-dubbed and Japanese-language format on January 30, 2007.[1]


Critical reception for the film by English language critics has been mixed.[2] DVD Talk gave the film a mixed review, writing "Sayonara Jupiter will intrigue and frustrate fans of Japanese fantasy cinema in equal measure, while mainstream American audiences will find it insufferably dull and unoriginal."[3]
