The film was rushed into production in order to replace "Red Beard", which fell behind schedule, in Toho's New Year's holiday slate. The Godzilla suit and Mothra larva prop were recycled from the previous film, with modifications added, while new suits were produced for Rodan and Ghidorah. Principal photography began and ended in 1964 in Mount Aso, Yokohama, Gotenba, and Ueno Park.
