National Radio Network (NRN; Japanese: 全国ラジオネットワーク, romanized: Zenkoku Rajio Nettowaku) is a Japanese commercial radio network. Both Nippon Cultural Broadcasting (QR) and Nippon Broadcasting System (LF) in Tokyo serve as the network's co-flagship stations; the Fujisankei Communications Group has an influence on both stations. Established on 3 May 1965, NRN is made up of 40 regional affiliates, including ten full-time affiliates and 30 stations that are dual-affiliated with the rival Japan Radio Network (JRN).
