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.

Teresa Teng (January 29, 1953 – May 8, 1995) (traditional Chinese: 鄧麗君; simplified Chinese: 邓丽君; pinyin: Dèng Lìjūn; Wade–Giles: Teng Li-chun; Pe̍h-ōe-jī: Tēng Lē-kun, Japanese: テレサ・テン), was an immensely popular and influential Chinese pop singer from Taiwan. Teng's voice and songs are instantly recognized throughout East Asia and in areas with large Asian populations. It is often said, "Wherever there are Chinese people, the songs of Teresa Teng can be heard." Her songs enjoy popularity among Korean, Japanese, Thai, Vietnamese, Malaysian, and Indonesian listeners as well.

Teng was known for her folk songs and romantic ballads. Many became standards in her lifetime, such as "When Will You Return?" (何日君再來) and "The Moon Represents My Heart" (月亮代表我的心). She recorded songs not only in her native Mandarin but also in Taiwanese, Cantonese, Japanese, Vietnamese, Indonesian, and English.^{[citation needed]}

Teng, a lifelong sufferer from asthma, died in 1995 from a severe respiratory attack while on holiday in Thailand. She was 42.
