Pop culture and junk food are a perfect combination: Both are brightly colored, easy to consume and totally moreish. Personally I can while away whole afternoons watching anime while stuffing potato chips and chocolate down my gullet. Sure,  I end up feeling a little sick and ashamed at the end, but while it lasts, the experience is sublime.

That's why convenience-store tie-in campaigns that target anime and movie fans make so much sense. A limited-edition K-On! Choco Snack has proven to be hugely popular, so popular that Gigazine discovered that it had disappeared off the shelves of the local Lawson within hours of going on sale Nov. 9.  In addition to the K-On! Fair at Lawson, this month Seven-Eleven and Family Mart are also running campaigns. Here’s a round up of what’s on offer:

  • K-On!, an anime about five high school girls who form a band, is the focus of Lawson’s campaign. K-On! fans can purchase special yaki-soba sandwiches, cold cocoa drinks, sticker sets and caramel corn. Fans can also accumulate points by buying Gogo no Kocha drinks, which then qualifies them to win lottery prizes that include T-shirts, K-On! figurines and a custom-made electric guitar.  Lawson is also selling K-On! phone cards, K-On! figurines (from Nov. 16) and tote bags (that can be purchased on Loppi). The campaign runs until Nov. 29.
  • Fans of One Piece should set sail for Seven-Eleven. Customers who spend over ¥700 can enter into a prize draw to win special pirate-themed One Piece booty. Some drinks also come with a free cell-phone strap.
  • To promote the upcoming release of "Space Battleship Yamato," Family Mart is running a special campaign until Nov. 29. Customers who spend over ¥500 can apply for a special lottery to win movie-themed goods. Sweetening the deal, Yamato-themed pastries and drinks are available.
