NOAH had a lot of trouble with the yakuza scandal earlier in the year, and they were just getting over Misawa's death. New Japan's been shaky for awhile but they're on the upswing in terms of popularity, they've had really awesome houses recently.
Youtube's an awesome place to enjoy Japan's wrestling from, simply because for NJPW, NOAH, AJPW, Dragon Gate & Zero-1's big wrestlers a lot gets posted, much of it's officially. It's easier sometimes to try to follow it by wrestlers themselves than promotions, unless you speak Japanese, haha.
As far as dvds, ivp videos has a lot of content and it's on the cheap too. They have a best of Curt Hennig in Japan DVD for a penny for instance. >_> I'd check it out if you're looking for Japanese wrestling DVDs.
