In Japan, February the 14th is a day when women give two kinds of chocolate away. Obligation chocolate, which is typically small and store-bought, and homemade chocolate. Homemade chocolate is given to significant others and crushes, whereas obligation chocolate is given to friends, coworkers, classmates, etc. This day is of course known as Valentine's Day. Notice we only mentioned women and not men. That's because... White Day, which takes place a month later on March 14th, is the reciprocal day where men who have received chocolate from a woman give her a gift in return that comes out to an equal value.
