Godzilla emerged from the sea to devastate Tokyo in the now-classic 1954 film, creating a global sensation and launching one of the world's most successful movie and media franchises. Awakened and transformed by nuclear weapons testing, Godzilla serves as a terrifying metaphor for humanity's shortsighted destructiveness: this was the intent of Shigeru Kayama, the science fiction writer who drafted the 1954 original film and its first sequel and, in 1955, published these novellas. Although the Godzilla films have been analyzed in detail by cultural historians, film scholars, and generations of fans, Kayama's two Godzilla novellas have never been available in English. This book finally provides English-speaking fans and critics the original texts. The novellas reveal valuable insights into Kayama's vision, feature plots that differ from the films, and display the author's antinuclear, proenvironmental convictions. Kayama's fiction depicts Godzilla as engaging in guerrilla-style warfare against humanity, which has allowed the destruction of the natural world through its irresponsible, immoral perversion of science. As human activity continues to cause mass extinctions and rapid climatic change, Godzilla provides a fable for the Anthropocene, powerfully reminding us that nature will fight back against humanity's onslaught. Shigeru Kayama (1904-1975) was a science fiction writer and scenarist whose early stories about monsters and mutated sea creatures attracted the attention of Toho Studios, which asked him to draft the first two Godzilla films. The film Half Human by Toho Studios was also based on one of his stories, and he contributed to the screenplay for the Toho film The Mysterians.
