The film has seen generally negative reception from English critics. Derek Elley of Variety compared the film to the Japanese film Tetsuo: The Iron Man stating that "where 'Tetsuo' had a cartoonish energy, 'Organ' is an increasingly limp farrago of body make up and ketchup. Fujiwara makes an impression as the bizarre one-eyed amazon, but her role, like all others, is undeveloped." Time Out London wrote that "Diminishing returns hit splatter movies faster than most other genres, and this starts straining for effect and repeating itself within its first hour". Jason Gibner of Allmovie awarded the film three stars and wrote that though the film "can often be impossible to watch, the overall bizarre nature of the film will hook some viewers who want to discover where this twisted gore fest will go next."
