No, seriously. Many years ago, the marketing geniuses -- and I do not use that term ironically -- at Kentucky Fried Chicken Japan started a campaign to convince Japanese consumers that a traditional Christmas dish is fried chicken. They succeeded wildly, not only to the point that people now need to make reservations to pick up their fried chicken on Christmas Day at "Kentucky" (as the place is nicknamed) and that they've expanded the product range to include "premium roasted chicken" on that day, but also that convenience stores and other fast-food chains have gotten into the act, also offering that traditional Christmas chicken.
Which explains why, last night, the 7-11 near my house had a table set up outside in the dark, displaying the Christmas cakes (another, albeit non-KFC, Christmas tradition) and the chicken, sold by three 7-11 employees, one in a Santa suit and the other two dressed as reindeer.
(The chicken didn't seem to be fried, but grilled, with a sweetish teriyaki sauce on top. Pretty tasty, actually.)
As for The Colonel above: there's a statute of him permanently outside every KFC in Japan, but he only wears the Santa suit at Christmas time. (There's a purely Japanese holiday where he dons a colorful suit of samurai armor, but that's something for another post.)
