Abstract
As the Tokyo Broadcasting Company (JOAK) started broadcasting performances by Japan Symphony Association and later the New Symphony Orchestra in its very early days, the Osaka Broadcasting Company (JOBK hereafter) started broadcasting performances by Osaka Philharmonic Orchestra in an early stage of its emergence. After almost four years of silence since June 1929, in April 1933 the company founded Osaka Radio Orchestra as well as Osaka Radio Symphony Orchestra. The main aim of the present paper is to investigate on the role of broadcasting orchestras in the production of JOBK programs. A conclusion drawn through investigation of the "List of Programs" of JOBK from 10th of May 1925 to the 15th of August 1945 as well as the newspaper articles regarding the programs is that, while Osaka Philharmonic Orchestra was active in the local area and its contribution was towards flourishing of Osaka culture, the roles of the Osaka Radio Orchestra and the Osaka Radio Symphony Orchestra were important in the production of those JOBK programs which were directed towards not only the local region, but also the nation as a whole.
