 Throughout the period of formal American rule in Okinawa, there were series of protests (including the Koza riot) against U.S. land policy and against the U.S. military administration.In 1956, one-third of the population advocated for independence, another third for being part of the United States, and final third for maintaining ties with Japan.Despite the desire of many inhabitants of the islands for some form of independence or anti-reversionism, the massive popularity of reversion supported the Japanese government's decision to establish the Okinawa Reversion Agreement, which put the prefecture back under its control.
