Godzilla Raids Again (1955)

Pilots Shoichi Tsukioka and Koji Kobayashi are scouting the ocean for schools of fish for Marine Fisheries KK, located in Osaka. Suddenly, the engine for Kobayashi's plane malfunctions and he makes an emergency landing on the remote Iwato Island. Hidemi Yajima, Tsukioka's lover and the daughter of the company's owner, informs him of the situation, and he immediately flies to the island to rescue his friend. Tsukioka sees Kobayashi's plane sitting atop the water near the island, with Kobayashi himself waving at Tsukioka's plane from the island. Tsukioka lands and reunites with Kobayashi, who has only suffered a sprained wrist in the incident. The two men hear strange noises coming from the cliffs on the island, then look to find two huge monsters battling on the island. Tsukioka immediately recognizes one of the monsters as Godzilla, but cannot identify the other. The grappling monsters tumble off the island into the ocean below, after which they both disappear.

Upon returning to Osaka, Tsukioka and Kobayashi report their story to the authorities. A conference with the JSDF, several scientists, including Kyohei Yamane, and the two pilots is held in Osaka, where they determine that the monster Godzilla was fighting is a creature called Anguirus. According to a report from a Polish scientist, Anguirus is a vicious dinosaur that lived during the same time as Godzilla, and harbored an intense hatred of violent creatures like Godzilla. Like Godzilla, Anguirus had been living deep underground only to be disturbed and awakened by recent nuclear testing. When asked how they can hope to stop Godzilla, Dr. Yamane shows footage recorded of the first Godzilla's raid on Tokyo the previous year, then regretfully states that there is no conceivable way to defeat this Godzilla. Yamane mentions that the first Godzilla was killed by the Oxygen Destroyer, a chemical weapon invented by Daisuke Serizawa, but unfortunately Serizawa had taken his own life to ensure the weapon could never be used again. Yamane offers one piece of advice: Godzilla harbors a strange instinct towards lights, possibly due to their reminding him of the atomic bomb that awakened him. If a blackout is enforced and flares are dropped offshore, Yamane believes Godzilla can be lured away from the mainland.

When Godzilla unexpectedly surfaces in Osaka Bay, a blackout is immediately enforced on the city as citizens are evacuated. Fighter jets fly over the bay and begin dropping flares, which successfully lure Godzilla away from the city. Meanwhile, a group of prisoners stage an escape from the truck transporting them, beginning a lengthy chase with the police across the port area. After the prisoners hijack a fuel truck, two pursuing officers get into a car driven by Tsukioka and ask him to follow the truck. Eventually, the truck flies off a ramp and crashes into a refinery, starting a raging fire that quickly consumes the port area. The fire soon draws Godzilla's attention, and he approaches Osaka once again. Anguirus also comes ashore, and resumes his battle with Godzilla. The JSDF opens fire on the kaiju, but their weapons have no effect as Godzilla and Anguirus begin tearing the city apart. Their battle destroys countless buildings, including the tuna cannery that Tsukioka and Kobayashi work for. Eventually, the two monsters reach Osaka Castle, which is destroyed as Godzilla tackles Anguirus into it. Godzilla then bites down onto Anguirus' neck, causing him to bleed profusely before falling into the moat below. Godzilla fires his atomic breath at his foe, burning him to death and leaving Godzilla the victor. He leaves Osaka ablaze and in ruins.

In the aftermath of the devastation, Tsukioka and Kobayashi find the cannery in ruins. Their boss informs Kobayashi that he will be transferred to the company's Hokkaido branch while he and his daughter clean up in Osaka. After he has been working in Hokkaido for some time, Kobayashi is informed that Mr. Tajima, Hidemi, and Tsukioka will be arriving in Hokkaido soon, and meets them one night at a company party. While Tsukioka and Kobayashi are catching up, they learn that one of the company's ships has just been sunk somewhere off the coast. Knowing Godzilla must be responsible, Tsukioka gets into his plane and begins scouring the surrounding waters despite Hidemi's protests. Tsukioka eventually finds Godzilla coming ashore on the remote icy Kamiko Island, and alerts the JSDF. Kobayashi switches shifts with Tsukioka to keep an eye on Godzilla while he flies to a JSDF base. As the military begins arriving on the island to attack Godzilla, Kobayashi notices the monster beginning to leave the island. He dive-bombs Godzilla with his plane, only to be blasted by his atomic breath and killed upon impact with the slopes of the island. As Tsukioka grieves for his friend, he notices an avalanche of ice falling from the area Kobayashi's plane struck, giving him the idea to bury Godzilla under ice. Tsukioka tells his plan to the JSDF, which begins an operation to blast the slopes of the island using fighter jets. After a few minutes, Godzilla is buried in snow up to his waist, as the JASDF pilots return to base to refuel and reload.

To prevent Godzilla from escaping the island, the JSDF lines the shore of the island with gasoline barrels and lights them on fire. Soon, the fighter jets return, with Tsukioka flying one. The jets open fire on the slopes again, and although some are shot down by Godzilla's atomic breath, Tsukioka and the JASDF are successful in completely burying Godzilla under the ice. With the menace finally halted, Tsukioka solemnly looks to the sky and says, "Kobayashi, we buried Godzilla for you."
