Hideto Ogata, played by Akira Takarada, is a character in the 1954 film Godzilla.
Ogata is a salvage ship captain who falls in love with Emiko Yamane despite her having fiance named Dr. Daisuke Serizawa due to an arrangement.
After consulting international experts, the Japanese Self-Defense Forces construct a 30 m tall and 50,000 volt electrified fence along the coast and deploy forces to stop and kill Godzilla. Dismayed that there is no plan to study Godzilla for its resistance to radiation, Yamane returns home, where Emiko and Ogata await, hoping to get his consent for them to wed. When Ogata disagrees with Yamane, arguing that the threat that Godzilla poses outweighs any potential benefits from studying the monster, Yamane tells him to leave. Godzilla resurfaces and breaks through the fence to Tokyo with its atomic breath, unleashing more destruction across the city. Further attempts to kill the monster with tanks and fighter jets fail and Godzilla returns to the ocean. The day after, hospitals and shelters are crowded with the maimed and the dead, with some survivors suffering from radiation sickness.
Distraught by the devastation, Emiko tells Ogata about Serizawa's research, a weapon called the "Oxygen Destroyer", which disintegrates oxygen atoms and causes organisms to die of a rotting asphyxiation. Emiko and Ogata go to Serizawa to convince him to use the Oxygen Destroyer but he initially refuses, explaining that if he uses the device, the superpowers of the world will surely force him to construct more Oxygen Destroyers for use as a superweapon. After watching a program displaying the nation's current tragedy, Serizawa finally accepts their pleas. As Serizawa burns his notes, Emiko breaks down crying.
A navy ship takes Ogata and Serizawa to plant the device in Tokyo Bay. After finding Godzilla, Serizawa unloads the device and cuts off his air support, taking the secret of the Oxygen Destroyer to his grave. Godzilla is destroyed, but many mourn Serizawa's death. Yamane believes that if nuclear weapons testing continues, another Godzilla may rise in the future.
