Battle Royale takes place in a fictional police state version of Japan known as the Republic of Greater East Asia. From time to time, fifty randomly selected classes of secondary school students are forced to take arms against one another until only one student in each class remains. The program was created, supposedly, as a form of military research, with the outcome of each battle publicized on local television. A character discovers that the program is not an experiment at all, but a means of terrorizing the population. In theory, after seeing such atrocities, the people will become paranoid and divided, preventing another rebellion.
