Warning from Space

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. It was written by Hideo Oguni based on Gentaro Nakajima's novel. In the film's plot, a starfish-like aliens "Pairan" (Japanese: パイラ人, Hepburn: Pairajin) 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.

Produced and distributed by Daiei Film under Masaichi Nagata, it was the first colored Japanese science fiction film, and was also the nation's first full-scaled science fiction film to feature an extraterrestrial race. The film also predates Daiei's most iconic tokusatsu characters, Gamera and Daimajin. Its special effects director was Toru Matoba, a notable figure among the tokusatsu genre who contributed in Ultraman-related contents and Spectreman after the 1956 film, and the prominent avant-garde artist Tarō Okamoto was Pairan's designer.
