Why Do Japanese People Ask for My Blood Type?

What Your Type Says About You
Here is the cheat sheet:

・Type AB: Mysterious, genius, dual personality. If you say you are Type A, people will nod and say, “I knew it, your desk is so clean!”

・Type A: Organized, serious, perfectionist (The typical Japanese image).

・Type B: Creative, wild, selfish, goes their own way.

・Type O: Easygoing, social, natural leader.

The “B” Prejudice
Be careful if you are Type B. In Japan, Type B often has a reputation for being “difficult” or “selfish” in relationships (though also charming). If you want to avoid judgment, or if you genuinely don’t know your type (which shocks Japanese people), just say “I don’t know.” It makes you look mysterious—like an AB!
