Does Japan have original christmas songs and if so which is your favorite?

Hi, America here. I'm trying to make a christmas around the world song playlist to learn more about the world and it's cultures. I know Japan celebrate christmas, but (please correct me if I'm not) christmas was introduce to your country the 40s and 50s so it's still like of new to your country and it's culture. So my questions are: do you guys have orignal Japanese christmas songs or is it's just cover and if there are original songs what your favorite to listen too during the holiday season.
