Unlike other parts of Japan, Okinawa has its own history. The Ryukyu Kingdom flourished for over 400 years from the 15th century. Japan integrated the Ryukyu in its society and changed the name of the islands to Okinawa prefecture in 1879. During World War II, the Battle of Okinawa took place involving civilians. From 1945, Okinawa had been under the control of the US Military until 1972. Many US Military bases are currently located in Okinawa. Okinawa conserves its unique traditions from the Ryukyu Kingdom, including the language, arts, and music.
