 This is not the first time legislation was considered for establishing both symbols as official.In 1974, with the backdrop of the 1972 return of Okinawa to Japan and the 1973 oil crisis, Prime Minister Kakuei Tanaka hinted at a law being passed legalizing both symbols.Main supporters of the bill were the LDP and the Komeito (CGP), while the opposition included the Social Democratic Party (SDPJ) and Communist Party (CPJ), who cited the connotations both symbols had with the war era.
