YouTube Hosts Kadokawa Episodes
Anime publisher Kadokawa (Karin, TokiKake, Lucky Star, Haruhi) has opened up their own YouTube channel. Among the videos uploaded include full episodes of some of their anime. The first episodes of both Full Metal Panic (above) & Mushi-Uta (below) are there right now, & it seems likely that more will follow. Aside from those, there are also many promotional videos for their other series. Keep in mind though that all of their videos are in Japanese & have no English subtitles, as their channel was made for Japanese viewers. You can still check it out for yourself, though. Their channel can be viewed here:
