Godzilla performer Haruo Nakajima, effects cinematographer Sadamasa Arikawa, and director Ishirō Honda were against the inclusion of the dance. Nakano recalled that audiences were divided over the dance. The design of the P1 rocket and astronaut suits were influenced by NASA's Project Gemini missions. Several P1 models were produced, with the biggest reaching 3 meters tall. In one scene, the effects crew wanted to show the 3-meter P1 lift from a low angle, however, its size would have exposed the top edge of the Planet X set. Against company policy, special effects art director Yasuyuki Inoue broke the sound stage floor, and dug a hole to allow the P1 to rise from the subterranean base. Inoue later got in trouble after the hole was discovered, however, Inoue would later repeat this technique in "Destroy All Monsters". The smoke effects in the Lake Myojin scenes were created by filling a thermos bottle with liquid nitrogen and destroying them underwater to create a chemical reaction. Effects animator Sadao Iizuka created the transport tractor beam and designed it after a Neon club sign he saw in Shibuya ward. For Godzilla, a new suit was produced by Teizo Toshimitsu. The new suit removed the kneecaps from the previous two film, the breast bone is slightly retained and deemphasized, the dorsal fins are less pointed, and the eyes are enlarged. The pupils were built to be moved from left to right. The suits for King Ghidorah and Rodan were recycled from the previous film, albeit with some alterations. For Ghidorah, the suit was repainted with a darker shade of gold, with less details on the faces due to settled rubber. For Rodan, the bulky tops on the wings were flattened and thinned. The melting radar dish model was independently built by a chief carpenter, Keiki Tanaka. "Invasion of Astro-Monster" was released in Japan on December 19, 1965 by Toho, on a double bill with "Young Beats". The film brought in about 3.8 million viewers in Japan and was the tenth highest grossing Japanese film for that year, earning a distribution rental income of ¥210 million during its theatrical run. Nick Adams' voice was dubbed over by Goro Naya for the Japanese release. It was re-issued in Japan in 1971 where it was edited to a 74-minute running time under the title "Kaiju daisenso Kingughidora tai Gojira" ().
