The Human Vapor was released theatrically in the United States in 1964 by Brenco Pictures Corporation. It was later re-released in a double-bill with Gorath in 1969. The American version re-structured the film from a mystery story to a narrative focused around Mizuno told from his point of view. Approximately eleven minutes of footage was cut, while a portion of Kunio Miyauchi's score was replaced with stock music, primarily from Paul Sawtell's score for The Fly (1958). Eventually, the rights to the film in the U.S. were acquired by Metro-Goldwyn-Mayer, who released it on VHS throughout the 1980's and 1990's. The film has not yet received a Region 1 DVD release.
After The Human Vapor proved a box office success in both Japan and the United States, producer Tomoyuki Tanaka began to plan for a sequel entitled Frankenstein vs. The Human Vapor. The sequel's premise would revolve around Mizuno, having actually survived the film's climax, seeking out Frankenstein's monster in order to find the secret of his immortality and use it to revive his love interest, who perished in the climax. However the film never came to pass, although Frankenstein's monster would later appear in Toho's Frankenstein vs. Baragon in 1965.
