Warning from Space (Japanese: 宇宙人東京に現わる, Hepburn: Uchūjin Tōkyō ni arawaru, lit. 'Spacemen Appear in Tokyo') is a 1956 Japanese tokusatsu science fiction film directed by Koji Shima. Produced and distributed by Daiei Film, it was the first Japanese science fiction film to be produced in color and predates Daiei's most iconic tokusatsu characters, Gamera and Daimajin. In the film's plot, starfish-like aliens disguised as humans travel to Earth to warn of the imminent collision of a rogue planet and Earth. As the planet rapidly accelerates toward Earth, a nuclear device is created at the last minute and destroys the approaching world.
