for the road construction board meeting after Yuasa asked the son of the company's president (working for Daiei at the time) to arrange the location. Daiei's dubbing studio was used as a laboratory set in the film's opening, with a few set pieces attached. The park scenes were filmed in Setagaya at the Futako-Tamagawa garden. Scenes of Nagoya Stadium were filmed at Ajinomoto Stadium. The ending theme Gamera's Song was composed and arranged by Akira Komachi, lyrics by Hidemasa Nagata, and performed by the Hibari Children's Choir. The song was released by Daiei Records as a single.

Nagata coined the name "Gyaos" for the monster. Yuasa "hated" adding scenes with military and scientific figures on the film, and other films as well, feeling that the characters were "useless" but seemed obligatory due to the 1954 film Godzilla. On Eiichi's role, Yuasa stated, "we wanted all the ideas to come from the child. It may be a bit silly but we didn't want theories of
