Kingu Kongu tai Gojira (1962)

Mr. Tako, the chairman of a pharmaceutical company, learns of roma tomato-sized berries that grow on Farou Island, are a miracle cure, and that the natives worship a god called Kingkong who has allegedly grown to giant size from eating the berries. What better way to promote the product, Tako figures, than to bring the creature back to Japan? So he leads an expedition with Sakurai and Furue to get the berries and the monster. Meanwhile, some American pilots discover the chunk of the glacier Godzilla was sealed in back in 1955. Sakurai's sister's boyfriend Kazuo is busy trying to sell an invisible but superstrong wire, which of course no one wants until Kong escapes...
