Telling Your Personality By Your Blood Type… Wait a Minute – WHAT?

Recently I walked up to a group of Japanese women and they were in the middle of a very deep conversation about each other’s blood type. I wasn’t sure what was going on, or why they had suddenly asked what mine was. I told them, then asked theirs and they proudly told me. Then I asked if this was something that they needed to know for an important reason – they responded, “Japanese people like to talk about blood types. There are many books written about them.” I still didn’t get it… finally I put two and two together and figured out what they were saying: you can tell a lot about a person based on their blood type. I decided to research this some more…

I’m still very confused. I guess I just don’t understand (or accept) that there could only be 4 types of people in the world! Yet I’m willing to accept that there are only 12 types of people in the world just so long as it’s according to the Zodiac  – and I believe(d) strongly enough at 17 to get my sign tattooed on me! (deep sigh and shakes head)

Let’s do a little more research…

According to,  since blood types weren’t discovered until 1901, character traits associated with each type are fairly new. The fascination with blood types may be strong within the Japanese culture (and no where else, at least not that I’ve ever heard of) because much of the research was done in Japan. goes on to say that in 1916 a Japanese doctor completed research on blood types linking them to characteristics of people; in 1925 the Japanese military evaluated soldiers based on their blood types; and during WWII the army and navy were set up based on their different blood types.


I’m still baffled…

With every strong belief in something (no matter how trivial) that differentiate people there will always be some wacko out there that will discriminate – and blood type is not immune. Mental Floss states that almost all Japanese – American baseball players are Type O (considered a warrior type). While this is good for the Japanese-American players, those players (especially in Japan) who are not Type O are often seen as less-than capable of playing professional baseball. Bura-Hara, the term explained by the New York Times, is the actual name given to discrimination according to blood type. The Guardian goes on to state that school classes are sometimes divided based on this theory and  jobs have been awarded to candidates partially because of their blood type.


I’m still shaking my head. I don’t think I will ever be a believer, although some of those characteristics seem to fit my personality… but I think I’ll just stick to Astrology!
