In Japan, Christmas is not traditionally a national holiday, but it has become a popular celebration in recent years influenced by Western culture. While there is no specific traditional Christmas dinner in Japan, some common foods that may be enjoyed during this time include fried chicken, Christmas cake, and sushi. Fried chicken, particularly from the restaurant chain KFC, has become a popular Christmas food in Japan due to a successful marketing campaign in the 1970s.

Sushi is another option that some families might enjoy for their Christmas meal.
