 The only notable Ryukyuan who advocated reversion between 1945–1950 was the mayor of Shuri, Nakayoshi Ryoko, who permanently left Okinawa in 1945 after receiving no public support for his reversion petition.In elections in late 1950, the Democratic League (then titled Republican Party) was defeated by the Okinawa Social Mass Party (OSMP), formed by Tokyo University graduates and schoolteachers from Okinawa who were against the U.S. military administration and advocated return to Japan.Media editorials in late 1950 and early 1951, under Senaga's control, criticized the OSMP (pro-reversion) and concluded that U.S. rule would be more prosperous than Japanese rule for Ryukyu.
