Closing credits epilogue: The segments of this picture depicting Japanese people and locales were written and filmed in Japan. Special credit is due the artists and technicians there who contributed much to the authenticity of this production.
For the American version of the film, the American company Distributors Corporation of America added English-language scenes and narration. The American version of the film contains the original Japanese footage with scenes of John Carradine as John Rayburn explaining the Snowman to his colleagues. The American version was released in the United States through DCA (Distributors Corporation of America) on December 10, 1958 as the bottom half of a double feature with Monster from Green Hell (1957). This version also removes Sato's film score. The American version features a scene of Carradine unveiling the young Snowman's carcass on a morgue slab, which involved the actual costume sent by Toho to the U.S. for filming. The added U.S. sequences were directed by Kenneth G. Crane.
