NHK AM, formerly known as NHK Radio 1 (NHKラジオ第1放送, NHK Rajio Dai-ichi Hōsō), is a national radio network in Japan, and is operated by the public broadcaster NHK. With its first broadcast on 12 July 1925, it is Japan’s oldest radio station,[1] and during World War II,[2] it often broadcast official announcements.

Its programming consists of news, and current affairs, and is broadly similar to that put out by national public broadcasters of other countries, such as the United Kingdom’s BBC Radio 4, and Radyo 1 in Turkey. NHK Radio 1 operates within AM frequencies. Their callsign is JOAK in Tokyo, but varies throughout the nation depending on location.

Following the closure of NHK Radio 2 in late March 2026, NHK Radio 1 was renamed NHK AM.[3]
