Yes, MUSIC FAIR is on two different channels, depending on the time that you watch. Apparently, they show this Fujisankei Sunday block or something with a bunch of Japanese programs on 18/18.1 and 44/44.1. But I'm not 100% sure when, since I was flipping channels once and I saw that AAA was on MUSIC FAIR with a bunch of other artists. I don't really know how late the broadcasts are compared to the Japanese ones but I'd say they air a few months after the initial broadcast.
As for Asian channels, 70% of the ones here in Southern California are Korean, with a handful of Chinese ones and ONE Japanese channel. 18.2 / UTB Hollywood. They show English subbed dramas, some anime, and a few variety shows every so often. The only music show they have is J-MELO, which is hosted in English and airs PVs of requested artists. The last time I watched it, they played some Dir en grey and Perfume's One Room Disco. I've looked at past broadcasts and people have requested songs like Ayu's Sparkle, so it depends on when you watch. (For many of the Off The Air channels, you need an antenna to watch them)
44.1
http://titantvguide.titantv.com/apg/...x?siteid=53631 - MUSIC FAIR shows at 6:30PM on Sundays.
[Hm, it appears that on further inspection, the Fujisankei lineup that was on 18.1 has officially moved over to 44.1]
