Happy Valentine's Day! February the 14th may mean flowers, a romantic dinner, or promises you don't intend to keep for other people, but to me it will always the Day Of Chocolate.
Valentine's Day is a very odd and overly commercialized day in Japan, where the giving and receiving of chocolate doesn't have that much to do with romance. Females are made to feel obligated to hand out chocolates to people they don't care about, such as teachers and bosses, while males anxiously wait to see if they get 'enough' chocolates to satisfy their egos. There are whole lines of inexpensive chocolate products suitable for giving, called giri choco (obligation chocolate). Unlike in the Western world, it's not a day for men to give something to their female love interests. (March 14th, called "White Day", has been sort of artificially designated as the males-give-back-to-females day.)
