Japan expanded to 95 MHz. The new spectrum is being promoted as ワイドFM (Wide-FM). The stations that are going in that spectrum are the existing commercial AM stations to add a FM simulcast for their AM stations.
The spectrum from 95~108 MHz has been reallocated to a service called multi-media broadcasting. This spectrum is divided into three 4.3 MHz channels. There is already one licensee. I am not aware yet of what services will be offered.
REC's website http://fccdata.org has extensive data on the Japanese AM, FM and TV stations (just click on the Japan tab).
