Valentine's Day in Japan is pretty different from the U.K. There's honmei choko (chocolate for someone you're into), giri choko (obligation chocolate), and even tomo choko (chocolate for friends)...
And a month later there's White Day to contend with.
One survey revealed that 90% of Japanese men said they didn't care about getting Valentine's Day chocolate, and wished women wouldn't bother. Click here to read an article I wrote for SoraNews24 on the subject.
(It's from a couple of years ago, but I think it's still super relevant... especially on Valentine's Day).
P.S. are you looking for the next instalment in the Calligraphers of Instagram series? It'll be back in March :)
Why not read Part 1, Part 1-and-a-half, and Part 2 while you wait?
