Some teenagers want to obtain a boat to find a brother. When they look around a boat without permission, they find a thief who takes them on his escape. They are caught in a storm and arrive at Letchi Island where natives of Infant Island have been enslaved by the terrorist organisation Red Bamboo. Red Bamboo runs a heavy water factory to process a juice which holds off the monster, Ebirah, which otherwise traps them on the island. The young men meet beautiful but tough Daiyo and wake up Godzilla to put an end to the Red Bamboo. Written by Scott Hutchins <scottandrewh@home.com>

Did You Know?


This film was originally written to star King Kong. That explains the uncharacteristic behavior of Godzilla, such as: Godzilla is found sleeping in a cave, when previous films have established that Godzilla rests underwater, he is awakened by lightning, just as King Kong was in King Kong vs. Godzilla (1962), and most uncharacteristically he is protective of Dayo, more typical of Kong's affection toward women.

Before he tears off Ebirah's claws, you can very clearly see the head of the stuntman inside Godzilla's suit through the big holes in the suit's neck. See more »

Change of guard brings change of style to Godzilla
31 May 2010 | by (United States) – See all my reviews

This is the second Godzilla movie to this point that wasn't directed by Ishiro Honda (first being Godzilla Raids Again), and was directed by Jun Fukuda. Fukuda chose Masaru Sato to compose the music instead of Akira Ifukube, and overall contributes to the lighter touch. Shinichi Sekizawa's screenplay continues on the trend of humanizing the monsters, and Ebira's pose before the battle is a caricature of the then popular professional wrestler Toyonobori, and Godzilla rubbing his index finger on his nose is a caricature of Yuzo Kayama's character in Wakadaisho series which usually played at same time as the Godzilla movies as a double feature. The cinematography is noticeably brighter and the characters are also bit more easy going than Honda's version of Godzilla movies.

Ryota (Tetsu Watanabe) who lost his brother in the South Pacific in a fishing boat accident believes in the prediction made by a spiritual medium in Mt. Osore that his brother is still alive. He comes out to Tokyo to look for a way to get to his brother. There he meets few college students and later a thief named Yoshimura (Akira Takarada) in a sailboat they've snuck into. While everyone's asleep, Ryota sets sail to the south pacific to search for his brother. In a stormy sea the sailboat runs aground on an island occupied by a gang who calls themselves the "Red Bamboo". Red Bamboo is kidnapping the residents of Infant Island (Mothra Island) as slave labor to further their cause. Dayo (Kumi Mizuno) a girl from Infant Island escapes into the jungle and meets Ryota and Yoshimura's crew. There they hide in a cave to escape Red Bamboo's pursuit. Unbeknownst to them, that cave contained a hibernating Godzilla. Yoshimura comes up with a novel plan to wake Godzilla and turn it against the Red Bamboo.

In this movie, the fairies that talks to Mothra also changed from The Peanuts (Emi and Yumi Ito) to another twins Pair Bambi (Yuko and Yoko Okada - born 4/19/1944 Nagoya Japan). They were already 15 year veteran in the show business when they stared in this movie. Originally, Noriko Takahashi was to play the part of Dayo, but fell ill to appendicitis so was changed to Kumi Mizuno at the last minute. Mizuno who was 29 at the time played the role written for a 19 year old girl. Takahashi 6 month earlier played a similar role in Tsuburaya Production's Ultra Q series as a native girl who lost her brother to a giant octopus.

In the mid to late sixties, Godzilla movie started to slide to a lighter stories. This movie took the formula one step further from the previous Godzilla move the "Monster Zero", and continues the humanization of Godzilla and the monsters. Jun Fukuda's directing isn't up to par with Honda's and the props look cheezy by comparison which took away from the story, but most likely the movie was intended for kids and this was part of their production plan. The good in this movie was Akira Takarada and Kumi Mizuno that brought character to acting. Overall the movie succeeded because these two characters kept the focus. Good entertainment from the '60s Toho studio.
