Rebirth is set in the year 2220, 21 years after the first Yamato story and 17 years after the story of the last film, "Final Yamato". A wandering, cascade black hole is approaching the Solar system, and will surely destroy all life on Earth. The decision has been made to evacuate Earth's entire population.
According to the official website for the film,[6] the planet to which Earth's population is being moved is called Amahr, ruled by Queen Iriya, some 27,000 light years away in the Sairam star system. When the film opens, that task is already under way.
