Valentine’s Day was first introduced to Japan in 1936 and has become widely popular. However, because of a translation error made by a chocolate company, only women
buy Valentine chocolates for their spouses, boyfriends, or friends. In fact, it is the only day of the year many single women will reveal their crush on a man by giving him chocolate. The men don’t return the favor until White Day, a type of “answer day” to Valentine’s Day, which is on March 14.
