Gappa (大巨獣ガッパ,   Daikyojū Gappa, lit. Colossal Beast Gappa) is a 1967 tokusatsu kaiju film produced by Nikkatsu Corporation. The film was released to Japanese theaters on April 22, 1967.


Playmate publisher Tonoka dispatches several of his employees, along with scientists from Toto University, on an expedition to the South Seas to collect rare animals for an island resort. Daize is fishing one night when he sees a pair of massive yellow eyes underwater, just before the ship is rocked by what his crewmates believe to be an earthquake. They scoff at his story.

Shortly thereafter, the captain notices a volcano erupting on Obelisk Island, and they decide to begin the expedition there. Itoko, a photographer, spots a statue resembling those on Easter Island as they approach. The island turns out to be inhabited, and they are quickly surrounded by men wielding spears as they enter the village. Once they announce they’re from Japan, however, the chief sets off a raucous celebration. Another group from Japan promised to return many years ago, and they believe the new arrivals will please a being called “Gappa.”

A young boy leads Hiroshi, a scientist, and Itoko to the statue, but tries to prevent them examining it. As they argue, another earthquake strikes and the statue topples, revealing the entrance to a cave. There, they and Daize discover a massive skeleton and a large egg. A third earthquake causes it to hatch, revealing a docile bird-lizard. Over the village’s protestations, the expedition brings the young monster to Japan. Their fears are well-founded: after the expedition leaves, two full-grown Gappa emerge from the cave and pursue the islanders into the sea. An American submarine rescues them.

Tonoka is enraptured with Gappa, and makes plans to smuggle it into the country, the better to preserve the secret until it can be unveiled at his resort. Kurosaki is reluctant to see the creature so exploited, but realizes it’s the only way he can be studied. Upon internment at the Toto University lab, the baby Gappa grows dramatically in size. By analyzing his brain waves, Kurosaki concludes that his hypothetical parents would be able to track his location.

After bursting out of the water behind the U.S. submarine, the adult Gappa buzz Haneda Airport before making landfall in Atami. The JSDF deploys tanks to stop them, but the monsters quickly incinerate them with their heat rays. Fighter jets engage them as they smash Atami Castle and are equally unsuccessful. The Gappa then submerge in Lake Kawaguchi to rest.

The next day, Playmate runs the baby Gappa as its cover story, and issues fly off the shelves. During a defense meeting, Hiroshi recommends using a sonic attack to lure the Gappa out of the lake, exposing them to a missile barrage. While his theory proves correct, the Gappa are unfazed by the missiles. Flying out of the lake and flooding the nearby town, they advance towards Tokyo.

Even amidst all the destruction, Tonoka refuses to release the baby, fearing that he would be ruined if his role in the parents’ rampage was revealed. Ultimately, however, he is powerless to stop Itoko, Hiroshi, and the military from taking the baby themselves. Two blimps towed by helicopters transport him to Tokyo, where his parents are wreaking havoc at an oil refinery. The family joyfully reunites at Haneda Airport and begins the long flight back to Obelisk Island.

Gappa was the fifth and final kaiju film project idea that Nikkatsu had come up with, after Giant Monster Gigant, Giant Squid Monster Arkitius, Giant Monster Momonra, and Reigon: Devil of the Seabed. Planning for all the unmade films was done by Hideo Kodama.[2]


Principal photography on Gappa lasted for about 40 days, twice the time that director Haruyasu Noguchi usually took to shoot a film.[1]

U.S. release

In July 1967, Gappa played at the Nikkatsu Theater in Honolulu, Hawaii, in Japanese with English subtitles.

American International Television released the film directly to television in 1968, as Monster from a Prehistoric Planet. The English dubbing was recorded by the Tokyo-based studio Frontier Enterprises. The international cut of the film runs six minutes longer than the Japanese release, with the majority of the furthered run time gained from the extension of the special effects sequences featuring the adult Gappas. The film's songs, "Colossal Beast Gappa" and "Don't Give Up, Baby Gappa!," were substituted with instrumental scoring, with the former replaced by an alternative orchestral piece.

  • Although Gappa shares the basic plot of a child monster rescued from human civilization by its parent(s) with the earlier Gorgo, screenwriters Gan Yamazaki and Ryuzo Nakanishi claimed to have never seen the movie.[1]
  • Stock footage of the parent Gappas appears in an episode of the British sci-fi comedy series Red Dwarf, "Meltdown", where they are enormous wax-droids roaming the Prehistoric World section of an abandoned theme park. Though intimidated, the mechanoid Kryten quips, "I can't believe how feeble and improbable those creatures were, sir. I've seen more convincing dinosaurs given away free with a packet of Wheaty-Flakes."
