The Mysterians
Japan's experience with Hiroshima and Nagasaki bored the well-known "Godzilla" (1954) and its many sequels, featuring mutation from the effects of nuclear radiation. This kickstarted the tokusatsu trend known as Kaiju films, a Japanese film genre that features giant monsters, usually attacking major cities and engaging the military and other monsters in battle. Other films in this genre include "Rodan" (1956) and "The Mysterians" (1957). Besides Kaiju films, Japan was also into ghost cat/feline ghost movies in the 1950s. These include "Ghost-Cat of Gojusan-Tsugi" (1956), and "Black Cat Mansion" (1958), which tells a story of a samurai tormented by a cat possessed by the spirits of the people she killed.
