KFC's Christmas promotion was the brainchild of Takeshi Okawara, who managed the first KFC restaurant in Japan. He would go on to become CEO of Kentucky Fried Chicken Japan from 1984 to 2002.
Just a few months after the first KFC opened in Japan in 1970, Okawara had the idea to sell a Christmas "party barrel," inspired by the elaborate American turkey dinner, but with fried chicken instead of turkey.
The promotion went national in Japan in 1974 under the name Kurisumasu ni wa Kentakkii: Kentucky for Christmas.
The party barrel campaign "filled a void," Joonas Rokka, associate professor of marketing at the Emlyon Business School in France, told the BBC. "There was no tradition of Christmas in Japan, and so KFC came in and said, this is what you should do on Christmas."

KFC helped build secular and commercial traditions with the simple message: "At Christmas, you eat chicken."
Today, KFC's Christmas meals contain more than just fried chicken.
Many packages contain cake, which has been an important part of Christmas in Japan since before KFC's expansion in the country.
Premium barrels include options such as ribs or roast chicken with stuffing.

At many Japanese Christmas parties, KFC is just one part of the Christmas feast.
Another major part of KFC's Japanese Christmas strategy is Colonel Sanders.
Across the country, KFC locations dress Colonel Sanders up in Santa Claus gear for the holiday season.
If you want to get in on the festive fun, however, you need to plan ahead. People are forced to wait in lines for hours on Christmas if they don't pre-order their holiday meals.
