Blood Type Personality: What Does Your Blood Type Personality Say About You?

‘In America, some people look up a potential partner's star sign to see their compatibility. If you are not shy to admit, you may have at one time, or another sought advice from the stars. Well, for Japanese people, they do not rely on the astrological signs of personality information; rather it is their blood type personalities.

A Japanese Perspective on Personality and Blood Types - In the western world, most people don’t give much thought to their blood types unless they donate blood or they have a medical emergency. In Japan, if you ask someone what their “type” is, they’re likely to describe it in terms of O, A, B, or AB. It’s their way of having blood type explained. As compared with other parts of the world, the Japanese culture and a few other Asian countries embrace some interesting ideas about the effect of someone’s blood type on their personality. While many people strongly believe that there is truth in the connection between personality types, blood types, and how people act, there is no real scientific evidence to prove it and there is no valid or reliable study about this. Many believe the Japanese’s take on personality and individual difference is more of a self-fulfilling prophecy. 

Takeji Furukawa was a social psychologist and a professor at Tokyo Women’s Teacher’s School who researched blood types and personality using Japanese subjects. He published a paper about this in 1927. Despite his lack of credentials, the study soon became a national conversation in Asian countries and around the world.

In another of Takeji Furukawa’s studies, he studied Japanese personality, and the like using the Formosans in Taiwan and the Ainu people of Hokkaid?. The Japanese occupied Taiwan after they invaded China in 1895 and the Taiwanese resisted and revolted, killing hundreds of Japanese. He found that just over 41% of Taiwanese samples had type O blood and assumed that their strong-willed and rebellious nature was due to O type blood in their genes. He supported his findings by reporting that slightly over 23% of the Ainu people had type O blood and they were submissive. Furukawa concluded from his Japanese subjects that Japan should strive to increase intermarriage with the Taiwanese to pare down the number of Taiwanese with type O blood. While the concept of the connection between blood type and personality took root in many eastern places, the general thought is that his results turned out to be little more than a self-fulfilling prophecy.

In the western world, many people put value and worth in their star signs and horoscopes. In some Asian countries, who you truly are is based on your blood. In Japan, this theory is a topic of interest and intrigue along the same lines as astrology. Some people believe that Japanese blood type, personality, and who you are go hand-in-hand.

Judging your characteristics based on your blood is such a common self-fulfilling prophecy that dating services and retail products have sprung up in response to it. People use these services and products to help them sort out individual differences. Believe it or not, there’s even a sort of discrimination and blood harassment surround this theory.’ (Source)
