Japanese women are used to taking the initiative on Valentine’s Day. In fact, it’s traditional for ladies in Japan to buy a nice box of chocolates for their objects of affection. Pay-back comes on White Day, when it's the men's turn to hand out the chocolates. Every year in Japan, vendors roll out new products and services to cash in on the dual rites of romance (as well as the obligatory giri choco for the office set).

Coincidentally, a recent survey carried out by the Ministry of Health, Labor and Welfare showed  evidence of an alarming trend that could affect Valentine Day's to come. If such surveys are to be trusted, less and less Japanese are having sex. The number of married couples doing it are down and more than a third of men between the ages of 16 to 19 just aren't interested.
