Gandalf,
White Day (March 14th) is also celebrated in Japan. I think it was pretty cool how there was a day for women to go after the men and buy them chocolate, send them a gift to their office, take them out for dinner, etc. And then March 14th the guy did all that for their woman. Quite a balance. In the USA I mostly see women being taken out for dinners, flowers sent to their office, women receiving jewelry from their man, etc.
