Subscribers to or purchasers of VIZ Media's Shonen Jump magazine have a special opportunity this month to enter sweepstakes for a chance to win a trip to Japan and attend the magazine's JUMP FESTA convention. And VIZ is also giving away collectible posters inside the magazine, starting with the August edition.

What has prompted this little spree? A couple of significant milestones! The Japanese parent, Weekly Shonen Jump, is celebrating its 40th anniversary this year, while the North American Shonen Jump, published monthly rather than weekly, was launched five years ago in November of 2002. Both magazines run serializations of action adventure manga, mostly targeted at young males. (For an idea of the sort of manga they publish, some examples include the wildly popular Bleach, Naruto, and One Piece stories, and even Death Note, though it has a slightly different feel than the usual Shonen Jump offerings.)

How can you enter for the chance to win this trip? It's a bit complicated, so be sure to check
