Confirmed for a mid February release:
Apogee & Perigee album
Jun Togawa albums
Guernica
Koji Ueno "Music for Silent Movies"
Circus have also had a compilation of their 1978 to 1981 material released which includes some session and production work by Sakamoto. I have one album of theirs "Horizon" and it was not exactly enthralling, so I'm probably not going to investigate further.
Off topic - I just heard "Last Pretender" by Pink Lady, which was an unexpected treat. It's a Takahashi production, also featuring Kenji Omura, and really sounds like something from the Susan albums or "Murdered By The Music". Fast tempo, lots of synths and cool drum fills. The track was a single A side so appears on most of their compilations.
