White Day is a day that is marked in Japan, South Korea, Taiwan, and China on March 14, one month after Valentine's Day. To make more money from Valentines day, the Japanese invented "White Day" as an excuse for men to buy candy to give to women in return for the chocolate that they received - there is even an official White Day site. The reason it is called "White Day" is because the color of sugar (white) is the main ingredient for candy which was traditionally given on White Day. White Day was first celebrated in 1978 in Japan.
