>>16976152>>16976155December 25th is not a national holiday in Japan, although December 23rd, which is the birthdate of the present emperor, is. Although it is not an official holiday the Japanese tend to celebrate Christmas, especially in a commercial way. The Japanese celebrate Christmas Eve by eating a 'Christmas Cake' which the father of the family purchases on his way home from work (or his wife does in the case where he has to work on Christmas Eve). Stores all over carry versions of this Christmas cake and drop the price of it drastically on December 25th in order to sell everything out by the 26th. This has resulted in a rather interesting expression in which young girls are referred to as a 'Christmas cakes': marriageable until their 25th birthday and requiring heavy discounts to get married after their 25th birthdays.
