Collection: Kaiju, Godzilla & Monsters

Kaiju, 怪獣 "strange beast", is a Japanese genre of films featuring giant monsters. 

The term kaiju (comes from the Chinese text Classic Mountains and Seas) which can refer to the giant monsters themselves, which are usually depicted attacking major cities and engaging the military, or other kaiju, in battle. 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, serves as a metaphor for nuclear weapons, reflecting the fears of Post-War Japan following the atomic bomings of Hiroshima and Nagasaki and the Lucky Dragon 5 Incident.

Other notable examples of kaiju characters include Frankenstein, Mothra, King Ghidorah, and Gamera. (Source: Wiki)
