School broadcasting has a relatively long history in Japan. Radio programs intended for school use were inaugurated by NHK (Japan Broadcasting Corporation) in 1935, and school television broadcasting began in 1953. As of April 1983, the NHK sends 13 hours and 50 minutes of radio programs and 33 hours and 30 minutes of television programs per week, which are aimed at various levels of students from kindergarten through senior high. Approximately 22,500 (or 90%) of primary schools use at least some of NHK's school broadcasts. One of the changes in educational broadcasting in schools in the past 10 years has been the diffusion of videotape recorders (VTRs), and the increase in use of recorded programs. Many schools are now setting up VTR tape libraries for school use. This paper introduces the history of educational broadcasting in schools, and discusses current problems of school broadcast utilization based on results from various research and studies, including nationwide annual surveys of the utilization of school broadcasting since 1950.
