Gappa, the Triphibian Monster

“Vast! Hideous! Invincible!”

In 1967, an expedition from Japan lands on a tropical island in the South Pacific, where the natives worship a deity called Gappa. After an earthquake splits open a cavern, Hiroshi Kurosaki (Tamio Kawachi) and the others find a baby reptile inside, and they carry it back to a zoo in Japan against the islanders' warnings. Haruyasu Noguchi sets the two full-grown parents moving toward Tokyo, looking for the child that was taken from them.
