if you're looking to watch variety shows dramacrazy.net has a few. it has most of the arashi shows with which are up to date with raw epis and many of the epis subbed.--mago mago no arashi chan, d no arashi, g no arashi, arashi no shukudai-kun, vs arashi, himitsu no arashi-chan and arashi ni shiyagare. the good thing about arashi shows are they are funny but educational and u can watch them with kids. my 9 yrs old sister loves d no arashi.
DC also has cartoon kat-tun but unfortunately most of the mirrors don't work. and i don't find them as enjoyable.
if you search tudou.com you can find other variety shows that are not on DC but are in raw japanese only.

just in case the link doesn't work, go to tudou.com and paste 天才!志村どうぶつ園 and the date of the episode for example:
天才!志村どうぶつ園110611. the show airs every saturday and i enjoy it even though i don't understand much of what they say, cute animals are cute in any language (かわいい)
