Fuji-Q Highland
For the shot of Eiichi climbing Gamera's shell, Yuasa filmed a stunt double climbing a ladder that was later layered into the shell. The Highland Park miniature was based on Fuji-Q Highland. The Hotel Hi-land miniature was inspired by the Hotel New Otani Tokyo, which upset the then-hotel president and told Daiei president Masaichi Nagata, "we're barely open yet Gamera has already broken it." For the scene of Gamera recovering underwater, a 20 centimeter prop was built and filmed in a fish tank. Lighting up Gamera's leg sockets for flying scenes cost ¥12,000 ($33) per socket. Gyaos' beam required optical work that cost ¥3,500 per cut.
