“Gappa the Triphibian Monster” (大巨獣ガッパ / Daikyojū Gappa), 1967 Japanese STB Tatekan Poster (First Release), Ultra-Rare Nikkatsu Kaiju Holy Grail, Professionally Conserved and Washi-Backed, STB Size (c. 51 × 145 cm)
This is an original Japanese STB tatekan poster issued in Japan for Nikkatsu’s 1967 kaiju spectacular Daikyojū Gappa, known internationally as Gappa the Triphibian Monster and on American television as Monster from a Prehistoric Planet. Produced in the dramatic STB format—two B2 sheets designed to display together as one towering vertical theatre poster—it is an exceptional country-of-origin piece from the first Japanese release. At approximately 145 cm (5 ft) tall, the composition has the monumental scale its subject demands, stacking multiple adult Gappas, the captured juvenile, a burning metropolis, military aircraft, Mt Fuji, the human cast and the colossal scarlet title into one wall-filling image.
More than simply rare Nikkatsu advertising, this poster represents the studio’s extraordinary one-off expedition into the giant-monster genre. Nikkatsu promoted Gappa as the first production from its special-effects monster unit, but no continuing kaiju series followed. The film consequently stands as the studio’s first and ultimately only full-scale Showa-era kaiju feature, making its original large-format paper especially significant to collectors of Japanese fantasy cinema.
Important note on authenticity: modern reproductions and decorative reprints of classic Japanese kaiju imagery circulate widely. This example is 100% original first-release Japanese theatrical paper from 1967. Both original B2 sections are present and have been professionally conserved using the traditional Japanese washi support. It is not a reproduction or later reprint.
Film background
Released by Nikkatsu on 22 April 1967, Daikyojū Gappa was made in colour and widescreen at the height of Japan’s mid-1960s monster boom. Nikkatsu was then renowned for its stylish youth, crime and action pictures, so its decision to enter a field dominated by Toho’s Godzilla films and Daiei’s Gamera series was an unusually ambitious change of direction. Rather than approaching the genre cautiously, the studio mounted a lavish special-effects production combining its established action personnel with elaborate miniature cities, military hardware, aerial sequences and three giant creature suits.
The film was directed by Haruyasu Noguchi, with an original story and special effects by Akira Watanabe, and a screenplay by Iwao Yamazaki and Ryūzō Nakanishi. The cast draws heavily from Nikkatsu’s own company of performers and includes Tamio Kawaji, Yōko Yamamoto, Yūji Odaka, Kōji Wada and a young Tatsuya Fuji.
The story begins when a Japanese magazine expedition lands on the remote South Seas location of Obelisk Island. After discovering a giant egg, the group takes the newly hatched Gappa back to Japan despite warnings from the islanders. Two enormous adult Gappas—capable of travelling through land, sea and air—emerge in pursuit of their stolen offspring, crossing Japan and devastating Atami, industrial districts and military positions as they search for the juvenile. The spectacle ultimately leads to Haneda Airport, where the captured creature is returned to its parents.
This family structure gives Gappa its distinctive identity. The adult monsters are not invading conquerors but enraged parents attempting to recover their child, allowing Nikkatsu to combine city-smashing spectacle with an unexpectedly emotional climax. It is a singular fusion of South Seas adventure, corporate satire, Nikkatsu action cinema and full-blooded kaiju destruction.
Poster design
This STB is among the most extravagant Japanese monster compositions of the period. The upper section opens in near-apocalyptic fashion: an adult Gappa descends over an airport and city engulfed in flame, while another huge winged silhouette cuts across the turbulent clouds above. At upper right, two enormous blimps suspend the captured juvenile Gappa in a cargo net, surrounded by smaller aircraft—a direct visualisation of the film’s central conflict.
A monumental close-up of Gappa’s horned, avian-reptilian head dominates the centre. Its glowing red-rimmed eyes, rough triangular scales, hooked beak and exposed fangs are rendered in acidic greens, black, cream and yellow, with a brilliant white heat ray slicing diagonally across the image. The close perspective gives the monster an almost tactile presence and provides one of the most memorable creature portraits found on any non-Toho kaiju poster.
The left side is anchored by the brilliant yellow 日活 Nikkatsu emblem, accompanied by sleek fighter aircraft and vertical red credits for the principal creative team. Along the right edge, the yellow advertising copy proclaims Gappa’s Mach 3 speed and ten-megaton destructive power, promising a storm of terror over the modern metropolis and announcing the picture as a lavishly financed Nikkatsu special-effects epic.
The lower panel is dominated by the enormous three-dimensional red title 「大巨獣ガッパ」, its angular lettering projecting forward in deep blue-black shadow. Beneath it, the human cast runs towards the viewer while military jets tear across the sky. Mt Fuji rises in the background as two adult Gappas surge through the sea; one fires its blazing heat ray towards a burning ship while the second charges through the waves. A compact “Gappa’s abilities” panel at lower right adds a wonderful period science-fiction detail, presenting the creature almost as a newly unveiled military weapon.
The complete design is unmistakably Nikkatsu: fast, crowded, colourful and action-driven. The artwork combines studio branding, monster spectacle, aviation imagery, scientific pulp, human adventure and emotional family drama within one towering composition. The blazing reds, saturated yellows, deep blues and mottled green creature tones remain remarkably powerful nearly six decades after printing.
Rarity and condition
Japanese STB tatekan posters were working theatre-display material and had a particularly low survival rate. Their two-sheet construction and imposing size made them vulnerable to pasting, trimming, tearing, separation and disposal after a film’s engagement ended. Complete first-release examples are therefore substantially scarcer than standard Japanese B2 posters. With Gappa representing Nikkatsu’s singular entry into the classic kaiju cycle, this is an ultra-rare and genuine holy-grail poster for collectors of Nikkatsu, Showa special effects and non-Toho monster cinema.
Condition is excellent in presentation due to professional conservation and museum-standard washi backing. The two sections have been brought to a beautifully flat, stable and display-ready state while retaining the poster’s authentic period surface and gently visible fold history. A tiny split at the top centre and minor edge stress were expertly mended using hand-torn kozo-fibre washi and reversible, pH-neutral wheat starch paste—a traditional Japanese paper-conservation method used for centuries on materials including sutras and ukiyo-e.
These repairs are strong, flexible and near-invisible, supporting the original paper without introducing harsh modern adhesives or compromising its fibres. The colours remain exceptionally vivid, particularly the enormous scarlet title, yellow Nikkatsu mark, blue-black sky and richly mottled Gappa imagery. Photographs of the reverse show the clean, even traditional washi support.
