Yes, Christmas is celebrated in Japan! While it is not a national holiday like in other countries, it has become increasingly popular in recent years. Many Japanese people have adopted western customs such as gift-giving, Christmas trees, and Santa Claus, though the holiday is often celebrated in a unique way. In Japan, Christmas Eve is the main focus, with couples often going out to eat or see a movie together. There are also many Christmas events and parades in major cities, and children can write letters to Santa Claus.
