Question

A lot of Japanese anime character's bio data includes blood type. What is the significance for this?

Answer 1

Well I guess it points to certain traits like having a short temper and stuff like that. Like Kyouya and Honey have the same blood type in ouran and everyone was freaked out cause Kyouya was like the "dark kind" or something like that with a short temper and sorta evil. xD I tried lookin it up. I came to a dead end. You can try tho.

Answer 2

Blood type in Japan is often used a bit like zodiac sign. Certain personality traits go with certain blood types. See the wiki article about it here for a list of those traits and a history of the practice:

Answer 3

Yeah, what they said. In Japan blood types are like astrological signs [Sagittarius, Gemini, etc.] in America. Maybe minus the horiscope part. Some blood types are said to have certain personality traits, habits, etc., and most people know what blood types have these things and what don't.

I wish I knew my blood type >.<

Answer 4

blood type is like horoscope in Japan.

people with A are supposedly ambitious and serious

people with B are social and energetic

people with O are a happy medium between the two

and AB is a split personality

at least, I think so.... I live in Japan but I can't say for sure, I've never really researched it or anything *shrug*

Answer 5

Wow is that off the wall, wonder what Hellboy's blood type is?  Evidently the creators of these characters wish to anthropomorph them.
