Christmas in Japan: Christmas is not a national holiday in Japan. In fact, Christmas make up less than 1 percent of the population. Recently, however, more and more Japanese people are enjoying Westernized Christmas traditional such as decorating their homes and trees with lights and exchanging presents. Christmas cake and chicken are popular Japanese Christmas food. Especially, we like buying KFC. Many Japanese people attach a great deal of importance to Christmas Eve rather than Christmas Day because it has come to symbolize something romantic to them .
