J-Wave (JOAV) is one of the leading broadcasters in Tokyo. Their format would best be described as CHR, but that isn't completely accurate. For those who might be interested in something a bit different, here is 90+ minutes of J-Wave recorded on 6 January 2015 (the 7'th in Japan). The mp3 is encoded at 192 (variable Bitrate)/44.1, and can be found here:
