Television in Japan was introduced in 1939. However, experiments date back to the 1920s, with Kenjiro Takayanagi's pioneering experiments in electronic television. Television broadcasting was halted by World War II, after which regular television broadcasting began in 1950. After Japan developed the first HDTV systems in the 1960s, MUSE/Hi-Vision was introduced in the 1970s.

In broadcasting, a flagship is the broadcast station which originates a television network, or a particular radio or television program that plays a key role in the branding of and consumer loyalty to a network or station. This includes both direct network feeds and broadcast syndication, but generally not backhauls. Not all networks or shows have a flagship station, as some originate from a dedicated radio or television studio.
