White Day is a holiday that was created by a concentrated marketing effort in Japan. White Day is celebrated in Japan, Korea, and Taiwan on March 14, one month after Valentine's Day. On Valentine's Day, women give gifts to men; on White Day, men who received chocolate on Valentine's Day return the favor and give gifts to women. This holiday is beginning to catch on also in America.
There are many theories about the origins of White Day, but according to one, the holiday began in 1965, when a marshmallow maker started marketing to men that they should pay back the women who gave them chocolate and other gifts with marshmallows. Originally it was called Marshmallow Day, and later it was changed to White Day.
