Koza riot
The Koza riot (Japanese: コザ暴動, Hepburn: Koza bōdō) was a violent and spontaneous protest against the US military presence in Japan on the night of December 20, 1970 and into the morning of the following day in Koza, now part of the city of Okinawa. Roughly 5,000 Okinawans clashed with roughly 700 US military police officers in an event which has been regarded as symbolic of Okinawan anger against 25 years of US military administration.
