Director and writer Noboru Iguchi decided to work on a film after the film "Piranha 3D" (2010) was popular in Japan. Iguchi was also influenced by the film "Attack of the Killer Tomatoes" by the idea of food attacking people. The film contains a number of action sequences which Iguchi said he wanted to be more comedic than his previous films. Yoshihiro Nishimura contributed to the special effects in the film.
