Since the Toei Company requested a plot for a tokusatsu TV series from Yokoyama, he wrote this manga. Yokoyama made the setting "Giant Robo follows only a hero" as a differentiation from his other character, Tetsujin 28, a giant robot which everyone can control.



Part 1Edit

The secret society "Big Fire", scheming to conquer the world, is furthering Project GR. The special investigation organization of the United Nations dispatches an agent in Country T to interfere with the plan. Daisaku Kusama, a Japanese tourist, is mistaken for the agent and is abducted by "BF".

Part 2Edit

Daisaku Kusama comes back barely alive to Japan with Secret Agent Azuma with GR1. However, "BF" plans an attempt on Daisaku's life to recapture GR1 and they let GR2 and GR3 attack Tokyo.

Part 3Edit

A bomber carrying a hydrogen bomb crashes into Japanese waters. The hydrogen bomb has already been recovered by "BF" though the bomber is recovered at once. "BF" demands that GR1 should be exchanged for the hydrogen bomb.


  • Daisaku Kusama: A teenage Japanese boy who was traveling to T Nation in order to study.
  • Azuma: The chairman of the Japanese branch of the special investigation organization of the United Nations.


Adaptations include:

  • Giant Robo (tokusatsu), a 1967-1968 live-action tokusatsu series based on the manga. Released in the US as Johnny Sokko and his Flying Robot. The US dub of series was condensed into a television movie titled Voyage into Space.
  • Giant Robo: The Day the Earth Stood Still, a 1990s direct-to-video series inspired by the manga.
    • Giant Robo: The Day the Earth Burned, a 2006 manga series from the creator of Giant Robo: The Day the Earth Stood Still.

GR: Giant RoboEdit

GR: Giant Robo (GR ジャイアントロボ, GR: Jaianto Robo) is an animated TV series written by Chiaki Konaka (Serial Experiments Lain, The Big O) and directed by Masahiko Murata (Jinki:EXTEND, Mazinkaiser) and produced by SoftGarage. The TV series is a re-imagining of Mitsuteru Yokoyama's manga and was created to commemorate Giant Robo's 40th anniversary.

GR premiered January 19, 2007. The series finished its run on July 6 of the same year, totaling 13 episodes, with the possibility for two further seasons.[1] As of 2019, the series appears to have been cancelled.

The story takes place at the dawn of the 21st century, when Earth is overrun by giant robots. Daisaku Kusama encounters one of these monsters, the titular Robo, in a ruin in Okinawa. Beckoned by forces he cannot understand, Daisaku is made to bond, body and spirit, with the ancient weapon and defend his homeland from the incoming evil.

A pilot for the show was made in 2005, which was a selection of scenes from the 1967 manga in animated form[2]. Due to a change in staff at SoftGarage, the idea of a faithful adaptation of Giant Robo was scrapped in favor for a modern world view, not unlike that of Neon Genesis Evangelion. The show also has elements of The Cthulhu Mythos in it, with the Giant Robos being ancient machines built to fight off Eldritch beings known only as "The Old Ones".
