A blog I ran into called TV in Japan lets you watch exactly that, TV in Japan.  The blog covers all types of clips and shows ususally with English subtitles from TV being played right now in Japan.

Sure we could try to index all the different clips and episodes on YouTube from TV shows in Japan, but there honestly is just too much.  TV in Japan finds funny clips each day and posts them to watch.  It’s a great way to see just what is going on over on TV over in Japan and a great way to find funny clips
