===Development===

A few weeks after ''[[Godzilla (1954 film)|Godzilla]]'' was released in November 1954, a welcome home party was held for executive producer Iwao Mori. During the party, Mori instructed producer [[Tomoyuki Tanaka]] to produce a sequel, due to Mori being pleased with the box office results for the first film.{{sfn|Ryfle|1998|p=61}}

[[Ishirō Honda]], director of the first ''Godzilla'' film, was unavailable to return to direct the sequel due to directing ''[[Lovetide]]'' at the time.{{sfn|Ryfle|1998|p=62}} Japanese publications indicated that Tanaka attached Motoyoshi Oda to direct the film, rather than waiting for Honda, due to Mori fearing to lose the momentum of the first ''Godzilla'' film's success.{{sfn|Ryfle|1998|p=62}} Film historians Steve Ryfle and David Kalat deduced that Oda was chosen to direct due to his experience with effects-driven films such as ''[[Eagle of the Pacific]]'', and his then-latest film ''[[The Invisible Avenger]]''.{{sfn|Ryfle|1998|p=62}}{{sfn|Kalat|2010|p=35}} Kalat added that Oda was a director content with accepting B–picture level assignments, stating, "putting such a man in charge of the Godzilla sequel then was a clear signal of intent: This was to be a quickie profit center, not an artistic indulgence."{{sfn|Kalat|2010|p=35}}

Screenwriter Takeo Murata originally wanted to show a scene of chaos and looting in the middle of the monster battle, but time and budget limitations forced him to drop this idea.{{sfn|Ryfle|1998|p=64}} ''The Dinosaur Book'' by [[Edwin H. Colbert]] was used during the film's conference scene.{{sfn|Ryfle|2007|loc=00:11:59}}

===Special effects===
The film's special effects were directed by Eiji Tsuburaya.{{sfn|Kalat|2010|p=34}} Some of the effects footage was shot at a slower speed, 18 frames per second. Three cameras were set to capture the effects footage. Two cameras were set at high speed, while the third was indirectly left at slow speed. Despite the error, Tsuburaya felt the slow speed footage was usable and since then, used different camera speeds for different scenes. Some Japanese publications identified Yoichi Manoda as the cameraman who accidentally left the third camera on slow speed, while others identified Koichi Takano as the culprit.{{sfn|Ryfle|1998|p=63}}

Haruo Nakajima portrayed Godzilla and Katsumi Tezuka portrayed Anguirus, respectively. Nakajima and Tezuka were able to move in the suits more fluidly due to the suits being made from lighter materials, as well as casting them from plaster molds to fit the suit performers' physiques. For Godzilla, the new design was sculpted by Teizo Toshimitsu. The Godzilla suit was constructed with a cloth-base where latex was applied over it. A motor was built into the head to move the eyes and mouth, with the batteries built at the base of the tail. Due to this, Nakajima felt discomfort each time he jumped in the suit. For Anguirus, Tezuka had to crawl on his knees with the bottom of his feet exposed. The effects crew hid this by placing trees, buildings, and other obstacles in the foreground and filming from certain angles that hid the hind legs.{{sfn|Ryfle|1998|p=63}}

[[Hand puppet]]s were built for close-up shots. The Godzilla puppet had a spray built in to depict the atomic breath. Some of the monster battles were photographed from low angles to emphasize size and scale. The Osaka miniature set was constructed at Toho's then-new soundstage No. 8, which allowed the effects crew more space to work in. The Osaka castle miniature failed to crumble as planned. Wires were attached to the castle that ran beneath the platform. Due to heavy construction, the model failed to collapse even when the suit performers rammed into it as the crew members pulled the wires. Tsuburaya ordered to "cut" but the crew members did not hear him and the castle model collapsed when camera were not rolling. Due to this, the model had to be partially rebuilt. The ice island battle was partially filmed on an outdoor set. To bury Godzilla in ice, an ice machine was borrowed from the Tokyo skating rink.{{sfn|Ryfle|1998|p=64}}

For the opening scene, Nakajima and Tezuka were required to be in the suits as they plummeted into the water in order to avoid having the suits float upon impact. Several handlers were on-set to prevent Nakajima and Tezuka from drowning.{{sfn|Ryfle|2007|loc=00:09:36}} A Godzilla prop equipped with a wind up motor was built to walk during the ice island scenes, however, the prop malfunctioned and was filmed in a stationary position instead.{{sfn|Ryfle|2007|loc=01:04:45}} Real snow was added for the ice island set.{{sfn|Ryfle|2007|loc=01:11:23}} Several shots of Godzilla reacting to the ice canyon explosions were filmed outdoors in order to avoid filming the roof of the studio set.{{sfn|Ryfle|2007|loc=01:13:31}}
