The Japan Broadcasting Corporation (Japanese: 日本放送協会, Hepburn: Nippon Hōsō Kyōkai), also known by its romanized initialism NHK, is a Japanese public broadcaster. It is a statutory corporation funded by viewers' payments of a television license fee.

NHK operates two terrestrial television channels (NHK General TV and NHK Educational TV), three satellite television channels (NHK BS; as well as two ultra-high-definition television channels, NHK BS Premium 4K and NHK BS8K), and three radio networks (NHK Radio 1, NHK Radio 2, and NHK FM).

NHK also provides an international broadcasting service, known as NHK World-Japan. NHK World-Japan is composed of NHK World TV, NHK World Premium, and the shortwave radio service Radio Japan (RJ). World Radio Japan also makes some of its programs available on the Internet.

NHK was the first broadcaster in the world to broadcast in high-definition (using multiple sub-Nyquist sampling encoding, also known as Hi-Vision) and in 8K.

History

NHK's earliest forerunner was the Tokyo Broadcasting Station (東京放送局), founded in 1924 under the leadership of Count Gotō Shinpei. Tokyo Broadcasting Station, along with separate organizations in Osaka and Nagoya, began radio broadcasts in 1925. The three stations merged under the first incarnation of NHK in August 1926. NHK was modelled on the BBC of the United Kingdom, and the merger and reorganisation was carried out under the auspices of the pre-war Ministry of Communications.
