Following American occupation of Okinawa and and the surrounding Ryukyu Islands from 1945-1952, which, in turn, was followed by US military control of the islands, Okinawa and the Ryukyu Islands were returned to Japanese administration on 1972-06-17. To celebrate the 50th anniversary of this event, stations QRV from the islands could append a three-letter island reference followed by the digits 50, throughout 2011. The appendices are tabulated below.
