FM broadcasting in Japan
The frequency modulation radio broadcast band in Japan is 76-90 MHz. The 90-108 MHz section was used for television for VHF channels 1, 2 and 3 until the analog shutdown occurred on July 24, 2011. The narrowness of the Japanese band (14 MHz compared to slightly more than 20 MHz for the CCIR band) limits the number of FM stations that can be accommodated on the dial.
In late 2013, the Ministry of Internal Affairs and Communications published a report proposing the expansion of the FM band to 95 MHz. Many stations that had been previously only available on the AM band were issued preliminary licenses to broadcast from 90-95 MHz. The first station to go on air in the expanded band was Nankai Broadcasting, which began test broadcasts on 91.7 FM on November 3, 2014.
==Receiver issues==
Many Japanese radios are designed to be capable of receiving both the Japanese FM band and the CCIR FM band, so that the same model can be sold within Japan or exported. The radio may cover 76 to 108 MHz, the frequency coverage may be selectable by the user, or during assembly the radio may be set to operate on one band by means of a specially-placed diode or other internal component.
Conventional analog-tuned (dial & pointer) radios may be marked with "TV Sound" in the 90-108 section. If these radios were sold in the USA, for example, the 76-88 section would be marked TV sound for VHF channels 5 and 6, with the 88-108 section band as audio FM.
