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 freqencies. 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]
