Son of Godzilla

A pool was set up on stage nine during the production (stage nine is one of the largest on Toho's lot in Setagaya). They used the pool, which was about five feet deep, to film the shot of Godzilla rising above the surface of the ocean. Haruo Nakajima (the actor in Godzilla suit for the water scenes) was on a cart on a rail. He held onto the handle of the cart while it was towed by a truck. As the cart moved forward, he slowly rose out of the water. He wore a very tiny air cylinder that contained enough air for about ten minutes. The water that rushed by his face while the cart was being towed made it very difficult for him to prevent the mouthpiece from coming out of his mouth.

Black vertical connection lines are clearly visible on the sky backdrop in every shot during the monster scenes.

The Japanese version includes a prologue featuring Susumu Kurobe and Kazuo Suzuki viewing Godzilla from the air.
