About Japan Radio Network

Japan Radio Network is a Japanese commercial radio network run by TBS Radio in Tokyo, owned by TBS Holdings. 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 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. 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.
