Kaiju (kaijū, from Japanese “strange beast”) or Japanese monster movies is a Japanese genre of films which feature giant monsters. The term kaiju (which comes from the Chinese text Classic of Mountains and Seas) 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 (“special filming”) entertainment. (Wikipedia)
