Yes, Japan is known for eating Kentucky Fried Chicken (KFC) on Christmas. It's become a popular Christmas tradition in Japan, and KFC restaurants are often booked months in advance for the holidays. The tradition started in the 1970s when a local KFC manager noticed that Christmas Eve was a slow day for business and decided to advertise a special Christmas meal. Since then, KFC has become a symbol of Christmas in Japan, and it's a beloved tradition for many families to celebrate with a KFC dinner.
