White Day - Origin

Origin

White Day was first celebrated in 1978 in Japan. It was started by the National Confectionery Industry Association as an "answer day" to Valentine's Day on the grounds that men should pay back the women who gave them chocolate and other gifts on Valentine's Day. In 1977, a Fukuoka-based confectionery company, Ishimuramanseido, marketed marshmallows to men on March 14, calling it Marshmallow Day (マシュマロデー, Mashumaro Dē?).

Soon thereafter, confectionery companies began marketing white chocolate. Now, men give both white and dark chocolate, as well as other edible and non-edible gifts, such as jewellery or objects of sentimental value, or white clothing like lingerie, to women from whom they received chocolate on Valentine's Day one month earlier. If the chocolate given to him was Giri choco, the man likewise may not be expressing actual romantic interest, but rather a social obligation.
