For Kinji Fukasaku, directing Battle Royale (2000) was a deeply personal and exceptionally professionally rewarding experience. Not only did he get to work with his son (Kenta Fukasaku, the writer of the film), the story of the film -- and book on which it was based -- reminded him of his time as a 15 year old in Japanese munition factories during the final years of World War II.
In creating the film, Fukasaku particularly drew upon an experience in July 1945 when the factory he was working in was hit by the bombs of Allied warplanes. Unable to escape the factory in time, Kinji and the other young workers in the factory dove under each other for cover from the bombs and other falling debris. Kinji was one of the lucky few who survived the violent ordeal. Those that did survive (Kinji included) had to dispose of the bodies of those who died during the bombing, causing Kinji to have a tremendous distrust for government (particularly the Japanese government) and adults in general.
To that end, Fukasaku included the words "words to the next generation" in the film as a way to encourage young people to 1) not trust everything the government tells them and 2) think about their lives and the actions they take during it.
