Japan Radio Network (JRN; Japanese: ジャパン・ラジオ・ネットワーク) is a Japanese commercial radio network run by TBS Radio in Tokyo, owned by TBS Holdings (which is a part of the major conglomerate Mitsui Group). Established on 2 May 1965, JRN is made up of 34 regional affiliates, including four full-time affiliates and 30 stations that are dual-affiliated with the rival National Radio Network (NRN) as a part of "cross-network" practice in Japan. While the Japan News Network, the television arm of TBS, has an agreement that forbids its affiliates (examples are RKK & MBS) to do news sharing with other stations affiliated with other networks, JRN allows its radio stations to do cross-network programming, mainly, with NRN programs, and other production companies (Including Tuesday Club programs.). Currently, JRN has 4 stations that are only affiliated with the network, which consists of key stations TBS Radio, CBC Radio, RKB Radio, and JRN-only affiliate RBC iRadio.2
