List of radio stations in Japan

The list of radio stations in Japan lists all the national/regional radio stations in Japan.

Because of governmental regulation, Japan has a relatively small number of radio stations. Japan also has a comparatively smaller number of radio listeners nationwide than most other developed countries as well as countries in the geographic region. This is because of several factors, including the cultural difference in perception of radio, the fact that cars in Japan come with dashboard televisions fitted as standard, as well as general disinterest in the medium among working younger audiences compared with other mediums, especially television. Generally, each prefecture has three NHK stations (two by 2025), one commercial AM station (some are also on FM), and one commercial FM station. Heavily populated areas, such as Kantō region or Kansai region, have more stations.

There are also an increasing number of AM stations that start broadcasting on FM (on 90-95 MHz) as a supplement. The stations that air on the band are called Wide FM (ワイドFM) or FM complementary relay station (FM補完中継局).

The listed stations with ★ signs also broadcast television. Many stations have multiple frequencies (repeaters).

Certain AM-only radio stations (or AM stations with limited FM simulcast coverage) will be broadcasting solely in FM by 2028. The switch will not affect Hokkaido and Akita Prefectures and will continue AM-FM radio simulcasts. NHK is excluded from the switchover, as they have separate plans to consolidate its radio services.

Since 2024, commercial radio broadcasters have begun temporarily shutting down AM radio broadcasts, as a trial-run to FM-only broadcasts in 2028. Initially, at least 34 radio stations (which would start from February or July 2024 and end in 2025) will participate in this move, with additional broadcasters joining in the coming months.
