A series of books about blood type were among this year’s bestsellers in Japan, leading publishing distributor Tohan Co. has announced in Tokyo.

Three books about Type B, Type O and Type A of the “Jibun no Setsumeisho” (Instruction Manual for My Self) series, written by Jamais Jamais and published by Bungeisha, were ranked in the third to fifth places respectively among the top-sellers in Japan in 2008 (December 2007 to November 2008).

Mainly bought by twenty- and thirtysomething women, the books reflect Japan’s obsession with blood typology.

Blood Type was the main factor in some cases of:

  • Job appointments
  • Bullying among kindergarten children
  • Termination of happy relationships

About 90% of Japanese know their blood type, often before they know how to tie their shoelaces. About 40% are type A, 30% are O, 20% are B and 10% are AB.

Some experts explain blood typology’s central place in the Japanese psyche by pointing to the rough similarity between the distribution of blood types and social classes in feudal Japan: the strong-willed samurai (O) and mild-mannered farmers (A), and smaller numbers of sensitive artisans (AB) and earthy tradesmen (B).

“Even though psychologists and scientists have denied the relationship between blood type and personality, many Japanese are still naive about the connection,” he told the Guardian.

Type A Reserved and prone to worry, sensitive perfectionists such as Britney Spears and Adolf Hitler.

Type O Decisive, self-confident, curious, and ideal for sport, including Elvis Presley and the Queen.

Type B Cheerful caring, flamboyant free-thinkers such as Jack Nicholson.

Type AB High-maintenance, distant, suited to arts, such as Mao Zedong.

  1. Quote: About 90% of Japanese know their blood type, often before they know how to tie their shoelaces.

    At first, I chuckled at that. Then I thought, hey, if my 5-yr-old self was lost with three people (Bob, type O neg, Jorge, type B, Miriam, type AB), a doctor and a hemorrhage that required a blood transfusion, knowing my blood type would come in handy. Granted, I’d probably be dead from lack of a transfusion kit and may trip over my loose shoelaces and fall into a conibear trap and die anyways.

    I’m also not five. So there you have it.

  2. Knowing your bloodtype is useful, but making important decisions based solely on such characteristic is not very wise, although I see why some people would do that.

  3. I’m type O and that description is so not me!

    I did enjoy basketball and can be very determined but I don’t see myself as being very confident.

    And yes basing a decision on something like your blood type isn’t a good idea.

    Educating yourself so you can make an informed decision would be the best thing to do.

  4. Yup, blood type is not only a big thing in Japan, but most Asian countries as well. At least Korea values blood type as being important. I’ve known a few instances where blood type becomes a huge factor in the interview process for getting a job. Insane, but true.

    I don’t think it to be wise, to determine the character and personal attributes of a person based on blood type, but then again neither do most people…^-^

  5. I see, it is not limited to Japan. It is sad that people still rely on superstitions at this day and age. Hopefully, the situation will change in a few generations.
