What’s your blood type?

Chances are, if you’re from North America, you had to think about that for a little bit. I get it – outside of medicine, most of us pay very little attention to the subject.

But things are quite different in Japan. Back in World War II, Japan based battle groups on blood type. In 1990, Japanese electronics company Mitsubishi created an entire team of only type AB workers. Today, kindergartens in the country group kids by blood type and have distinctly different education plans for each.

You see, the Japanese believe that one’s blood type has a direct impact on their personality and abilities in a number of areas. This belief came about thanks to the work of blood type humanics pioneer Masahiko Nomi in the 1970s.

What This Means For You

What follows is a quick rundown of each blood type and the purported characteristics for each.

Blood Type A


Individuals with type A blood put others first. They’re great listeners and make for excellent friends. What they’re not so good at is expressing their own emotions – they’d much rather bottle things up and cater to the needs of others. Over time, this can lead to issues like depression and anxiety.

Type A individuals excel as accountants, librarians, attorneys, economists and writers. In love, they are most compatible with other type A individuals or AB ones.

Blood Type B

Those with type B blood are what you’d call extroverts. Like type A individuals, they make for great friends and listeners – but not at their own expense. To the contrary, they have little problem expressing their own emotions and putting themselves first when necessary.

Type B individuals are highly tuned to body language and can read others very intuitively. Because of this, they make for great psychiatrists, detectives and journalists. In love, they get along well with other B individuals or AB ones.

Blood Type AB

This is the rarest and most spiritual of all blood types. Individuals with this type of blood are also very rational and level-headed. They are excellent at planning and organizing. Type AB individuals tend to over-produce hormones like adrenaline, leading to very high and intense moods. They excel in public relations as well as managerial and educational positions.

In relationships, they get along well with all blood types.

Blood Type O

This is the most common blood type. Type O individuals crave power. They’re very competitive and tend to focus more on making progress than making friends. Because of this, they are very proficient in leadership positions.

They excel as accountants, politicians, businessmen and women as well as therapists.



Within each of the types above, there is a smaller subset known as Rh-negative. Only 15% of the U.S. population has Rh-negative blood. If you are Rh-negative, many of the characteristics of your primary blood type will apply, in addition to a few extra.

For example, Rh-negative individuals have a higher IQ than average as well as intense empathic qualities. They usually have many unexplained phobias. They can get along well with individuals of any other blood type but when it comes to reproduction, caution must be taken if their partner is Rh-positive. Medical injections of Rh immune globulin will prevent Rh-incompatibility, where the mother’s body attacks the fetus.
