It is. You've probably seen it if you watched animes... Japan has 2 types of Valentine's Day. During the actual Valentine's, girls give boys chocolate, flowers etc and then on "White Day" which is on March 14 it's the boys turn to give the girls gifts. So basically Valentine's (as in the day itself) in Japan is mostly about the boys.
that sounds like a huge hassle. why not just do both on the same day?!? idgi
