Tokyo Tower has use radio broadcasting
Broadcasting
Tokyo Tower, a member of the World Federation of Great Towers, has been used by many organizations for broadcasting purposes. The structure was intended for broadcasting television, but radio antennas were installed in 1961 because it could accommodate them. While analog and digital television broadcasts are no longer conducted from the site, two FM radio stations remain on Tokyo Tower. Stations that use or have used the tower's antenna include:
CurrentTokyo FM (JOAU-FM): 80.0 MHz
InterFM (JODW-FM): 89.7 MHzFormerNHK General TV Tokyo (JOAK-TV): VHF Channel 1 (Analog)

Japan employs both analog and digital broadcasting. In July 2011 all television broadcasting was changed to solely digital. Tokyo Tower is not a reliable broadcasting antenna for completely digital broadcasting because the tower is not tall enough to transmit the higher frequency waves to areas surrounded by forests or high-rise buildings. As an alternative, a new 634-meter-tall (2,080 ft) tower called the Tokyo Skytree was opened in 2012. In an attempt to make Tokyo Tower more appealing to NHK and the five other commercial broadcasters who planned to move their transmitting stations to the new tower, Nihon Denpatō officials drafted a plan to extend its digital broadcasting antenna by 80 to 100 meters at a cost of approximately ¥4 billion (US$50 million).As a result of their move to the Skytree, only one digital television station remained on Tokyo Tower: that of the Open University of Japan, whose JOUD-DTV and JOUD-FM continued on the tower until shutting down in 2018. FM radio stations will continue to use the tower for broadcasting in the Tokyo area. Masahiro Kawada, the tower's planning director, raised the possibility of the tower becoming a backup for the Tokyo Skytree, depending on what the TV broadcasters want or need.The antenna's tip was damaged on 11 March 2011 by the Tōhoku earthquake. On 19 July 2012, the Tokyo Tower's height shrank to 315 meters while the top antenna was repaired for damage from the earthquake.
