The company was also the main sponsor of the anime series Tetsujin 28 (1963—1966, the original Japanese version of Gigantor).
The idea of a robot controlled by a young hero was first used in 1956 with Iron Man 28 or Tetsujin 28-go (dubbed and released in the US as Gigantor), by manga artist Mitsuteru Yokoyama, which featured a giant robot piloted by remote-control by a young boy named Shotaro Kaneda, who used it to fight against evil.
