The Kaiju Art Collection Spanning from Godzilla to Gamera, and from Ultraman to Any Miscellaneous Giant Monster Movies, from these Monster Loving Deviants. Plus, I always Like to Draw Giant Monsters, and I still Do. KAIJU is a Japanese genre of films and television featuring giant monsters. The term kaiju can also refer to the giant monsters themselves, which are usually depicted attacking major cities and battling either with the military or other monsters. The kaiju genre is a subgenre of tokusatsu (特撮, "special filming") entertainment. The 1954 film Godzilla is commonly regarded as the first kaiju film. Kaiju characters are often somewhat metaphorical in nature; Godzilla, for example, serves as a metaphor for nuclear weapons, reflecting the fears of post-war Japan following the atomic bombings of Hiroshima and Nagasaki and the Lucky Dragon 5 incident. Other notable examples of kaiju characters include Rodan, Mothra, King Ghidorah, and Gamera.
