There is the uniquely Japanese system of believing that a person’s blood-type determines character. While there has never been any scientific evidence to support this claim, it is a surprisingly pervasive belief among Japanese, and the chances are that you are more likely to be asked your blood type than your sign.
The idea of blood type determining character was first put forward in 1927 by Takeji Furukawa. The idea was popular for some years, but faded from public consciousness upon his death until revived again in the 1970’s by journalist Masahiko Nomi who has since published over 16 books on the subject. Add to this several dozen books by other authors and a slew of TV programs, and you get an idea how much the idea has gripped the Japanese public. Several of these books have been translated into English, and a few books have been written by western authors, mostly in the area of New Age studies. Here some of the characteristics attributed to each blood type:
calm, composed, serious, reliable, perfectionist, arrogant, suppress their emotions.
curious, bright, cheerful, enthusiastic, superficial, unreliable, selfish.
carefree, generous, independent, flexible, clumsy, flighty.
sensitive, considerate, careful, efficient, strict, moody
The most common blood type in Japan is A, with 38% of the population. The most common in Britain and the U.S. is Type O. Interestingly the most common type among Japanese Prime Ministers is O.
