While millions do celebrate Christmas with KFC, others in Japan treat it as a romantic holiday similar to Valentine’s Day, and couples mark the occasion with dinner in upscale restaurants. For other Japanese families, Christmas is acknowledged but not celebrated in any particular way.

But for those who do partake, it’s not as simple as walking in and ordering. December is a busy month for KFC in Japan – daily sales at some restaurants during the Christmas period can be 10 times their usual take. Getting the KFC special Christmas dinner often requires ordering it weeks in advance, and those who didn’t will wait in line, sometimes for hours.

The genesis of Japan’s KFC tradition is a tale of corporate promotion that any business heading to Japan ought to study, one that sounds almost like a holiday parable.

‘Kentucky for Christmas’

According to KFC Japan spokeswoman Motoichi Nakatani, it started thanks to Takeshi Okawara, the manager of the first KFC in the country. Shortly after it opened in 1970, Okawara woke up at midnight and jotted down an idea that came to him in a dream: a “party barrel” to be sold on Christmas.

Okawara dreamed up the idea after overhearing a couple of foreigners in his store talk about how they missed having turkey for Christmas, according to Nakatani. Okawara hoped a Christmas dinner of fried chicken could be a fine substitute, and so he began marketing his Party Barrel as a way to celebrate the holiday.
