The series aired in Yomiuri TV from October 6, 1974 to March 30, 1975, totaling up to 26 episodes. It revolves around the character Susumu Kodai (Derek Wildstar in the English version) and an international crew from Earth, tasked during an interstellar war to go into space aboard the space warship Yamato, derived from the World War II battleship of the same name, in response to a message of aid from the planet Iscandar in order to retrieve a device which is able to reverse the radiation infecting Earth after being bombed by the Gamilas (Gamilons).

Space Battleship Yamato is one of the most influential anime series in Japan. Its turn toward serious themes and complex storylines influenced later works in the medium, including Gundam, Evangelion, and Macross, in addition to influencing the style of video games such as Space Invaders.
