Tokusatsu has origins in early Japanese theater, specifically in kabuki (with its action- and fight-scenes) and in bunraku, which utilized some of the earliest forms of special effects, specifically puppetry. Modern tokusatsu, however, did not begin to take shape until the early 1950s,[citation needed] with the conceptual and creative birth of Godzilla, one of the most famous monsters (kaiju) of all time.
