NHK World is the international broadcasting service of NHK (Nippon Hōsō Kyōkai - Japan Broadcasting Corporation), Japan's public broadcaster. The service is aimed at the overseas market, similar to BBC World News, Press TV, DW-TV, France 24 and Russia Today, and broadcast through satellite and cable operators throughout the world.

NHK World provides three services: NHK World Radio Japan, NHK World TV, and NHK World Premium. NHK World also makes most of its programming available through an online version of the television channel.

NHK Asia TV started broadcasting in 1995 as a service for Japanese expatriates in Asia. On April 1, 1998, NHK Asia TV was re-branded as NHK World Television to reflect its status as a global broadcaster following its expansion outside Asia. NHK's news and information channel broadcasts internationally via satellite and cable TV. Programming is broadcast in English. It began as a news channel in February 2009 using the traditional NHK World logo in their own digital on-screen graphic (DOG). Previously, NHK World TV used the traditional "3 Eggs" logo of NHK. The NHK World DOG in the news program, Newsline, is on the bottom left corner of the television screen. In other programming, the DOG is moved to the top left corner of the television screen. Some of the shows are produced by production studio JIB TV which is 60% owned by NHK with the remaining 40% owned by private investors like Microsoft and Japanese bank Mizuho. The NHK World DOG is not used at all when shows produced by JIB TV are aired.

NHK (日本放送協会, nippon housou kyoukai; official English name: Japan Broadcasting Corporation) is Japan's national public broadcasting organization. NHK, which has always identified itself to its audiences by the English pronunciation of its initials, is a publicly owned corporation funded by viewers' payments of a television license fee.

NHK operates two terrestrial television services (NHK General TV and NHK Educational TV), two satellite television services (NHK BS-1 and NHK BS Premium, both now high-definition television services), and three radio networks (NHK Radio 1, NHK Radio 2, and NHK FM).

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

Until the 1940s, NHK was a national radio broadcasting monopoly.

On 22 March 1925, one and a half years after the Great Kantō earthquake, Radio Japan produced the first radio broadcast in the country, transmitting from Atago Hill just north of the Tokugawa Tombs in Shiba Park. The first programme included Beethoven, classical Japanese music, and a play by Ōyō. In the same year, there were also broadcasts from Ōsaka and Nagoya.
