Plot

Activity in the Fuji volcanic zone shakes the Japanese archipelago, and a giant monster emerges from the crustal disturbance and is named Gyaos3. Around Mount Fuji, construction of a national expressway is stalled by a standoff between the road corporation and villagers led by the elderly village headman Kanamura, who holds out for higher land prices3. A helicopter carrying a survey team is shot down by a mysterious beam, and the boy Eiichi, grandson of the village headman, encounters the winged monster9.

Gyaos is nocturnal, a weakness Eiichi discovers, prompting the authorities to use 600-candela AGIL illumination flares against it3. Driven off by the light, Gyaos flies to Nagoya, destroys Nagoya Castle, and sets the area ablaze; Gamera, drawn to fire, arrives and the two monsters fight3. Gyaos cannot rotate its neck and fares badly once the battle moves over the sea, escaping only after shaking Gamera off3.

The Gyaos countermeasure headquarters learns that sunlight destroys Gyaos's cells and tries to lure it with a blood substitute into a rapidly rotating hotel lounge, pinning it until sunrise, but the plan fails for lack of electric power3. Finally the authorities start a mountain fire to summon Gamera, and Gyaos, drawn to the flames, fights Gamera across the sky until Gamera defeats it and drops it into a volcanic crater3.

Production

Daiei had entered the kaiju field in 1965 with Gamera: The Giant Monster, directed by Yuasa, breaking what the BFI's program notes describe as Toho's monopoly on Japanese giant-monster films and helping to touch off the mid-to-late 1960s "Kaiju Boom" in which every major Japanese studio produced kaiju pictures7. Yuasa had directed the first film and served as special-effects director on the second, Gamera vs. Barugon (1966); on Gamera vs. Gyaos he directed both units himself5. The special-effects crew included cinematographer Kazuo Fujii, art director Tomohisa Yano, and monster fabrication and operation by Ex Production5.

Yuasa later testified that the film's budget was close to an "A" on an A-to-C ranking scale, according to an account citing his remarks in Kyodai Tokusatsu Daizenshu8. He also explained his staging of the title monster in practical terms: "So I had Gamera crawl as much as possible" (湯浅憲明, quoted in Nihon Tokusatsu Gensō Eiga Zenshū)8.

The music was composed by Tadashi Yamanouchi, and the theme song "Gamera no Uta" ("Gamera's Song", King Records) was sung by the Hibari Children's Chorus, with lyrics by producer Hidemasa Nagata and music by Akira Komachi6.

Gyaos and the series

Gyaos's weapons define the character: its eerie cry becomes an ultrasonic blade that slices jet aircraft in two, and its 172-meter wingspan blows thirty tanks aside with a single flap; its favorite food is human blood10. The allcinema synopsis notes that Gyaos was designed with a silhouette based on straight lines, in deliberate contrast to Gamera, and that this design and its ferocious personality won the monster enormous popularity as a rival kaiju; Gyaos returned as Space Gyaos in the production Gamera vs. Guiron (1969)9.

The film is also credited with fixing two things about the franchise. Eiga.com's synopsis states that Gyaos's debut established the "friend of children" image that became a hallmark of the Showa Gamera series and made that popularity secure2. The BFI program notes for the 4K restorations state that Gamera vs. Gyaos "established two foundations of the Gamera series"7. The child character is handled with some balance: allcinema's commentary observes that from this film the interaction between Gamera and children is clearly drawn, but here the child is not pushed to the front of the story and instead functions as the one who produces novel ideas adults cannot, in equilibrium with the adult-side drama9.

The human plot centers on the expressway dispute, and Eiga.com's commentary credits the film with a notably fair construction: rather than a simple binary of state power versus oppressed local residents, the road corporation's site manager is played by series regular Kojiro Hongo, the laborers left on site are a likable comic pair, and the leader of the opposition movement, the village headman's granddaughter, is secretly favorable to the highway development2.

Restoration and later screenings

For Gamera's 60th anniversary in 2025, KADOKAWA produced 4K digital restorations of the first three Showa Gamera films, supervised by director Shinji Higuchi, the special-effects director of the 1990s Gamera trilogy, and by Shunichi Ogura, a specialist in 4K restoration of classic films11. The restorations premiered in Japan at the Showa Gamera Film Festival beginning December 5, 2025, at Kadokawa Cinema Yurakucho and other theaters2. A 4K digital restoration Ultra HD Blu-ray (HDR edition) was released on November 21, 2025, with a theatrical trailer, an interview with Higuchi and Ogura, and archival Spunichi Creates featurettes among the extras1.

The films were restored in 4K by KADOKAWA at IMAGICA Entertainment Media Services from scans of the original 35mm negatives, with color grading supervised by Higuchi and Ogura12. The international premiere of the Gamera vs. Gyaos restoration took place at BFI Southbank in London on February 28, 2026, alongside the restorations of Gamera: The Giant Monster and Gamera vs. Barugon7.
