Wiki Info - Half Human, originally released in Japan as Jūjin Yuki Otoko (獣人雪男, lit. "Monster Snowman"), is a tokusatsu film produced and released by Toho Film Productions Ltd. in 1955. The film was made by Toho's Godzilla production team, consisting of Ishirō Honda, Eiji Tsuburaya, and Tomoyuki Tanaka. This was director Honda's second assignment in the kaiju genre, after the original Godzilla (1954).
According to Wikipedia Japan, the film has been removed from circulation due to the original version depicting the inhabitants of the remote village similar to the Ainu people as being deformed from generations of inbreeding as well as showing backwards and violent behaviour. However, no such reference is made in the film's dialogue, but for this reason broadcasters and media publishing companies have refrained from showing it.
