A broadcasting station that is at the center of a broadcasting network and produces, organizes, and transmits programs. In broadcasting terms, it is also called a core station. In commercial broadcasting, it also plays a central role in terms of sales. The key stations of TV Asahi, TV Tokyo, TBS Television (→Tokyo Broadcasting Holdings), Nippon Television Network Corporation, and Fuji Television are located in Tokyo, with stations in Osaka serving as quasi-key stations. The key stations provide broadcast programs to the regional broadcasting stations (local stations) under their respective affiliations. Although local stations also produce programs, the proportion of programs produced by key stations is very large.
