I've been addicted to Asian shows this past few months and it cause me always to wonder why when I search for actors profile especially Japanese and Korean, I always see their blood type included. I researched and here's what I've found out:
Beginning in approximately 1930, the Japanese embraced the idea of matching personality traits with one's blood type. This phenomenon is as popular in Japan as the idea of matching horoscope with personality is in the States.
Almost all Japanese are aware of their blood type. The idea began when some in the west were touting the idea that the Asian peoples were more closely related to animals than humans, or lower on the evolutionary chain, since type B blood was the predominant blood type in Asians and animals. As ludicrous and unscientific as this idea was, it was insulting to say the least. Modern science disproves this obviously faulted idea. In the 1930's Furukawa Takeji (1891–1940) set out to disprove this notion and a new idea was born.
However, the idea of personality traits being influenced by blood type remains. Companies in Japan even had divided workers by blood type.
Here are the general ideas of each blood type. The Rh factor plays no role in the blood type/personality idea:
TYPE A-THE FARMER
People with blood type A have a deep-rooted strength that helps them stay calm in a crisis when everyone else is panicking. However, they tend to avoid confrontation, and feel very uncomfortable around people. A types are shy and sometimes withdrawn. They seek harmony and are very polite, but all the same feel that they never really fit in with others. A types are very responsible. If there is a job to be done, they prefer to take care of it themselves. These people crave success and are perfectionists. They are also very creative, and the most artistic of all the blood types, most likely because of their sensitivity.
People with blood type A are also likely to be considered classic "type A's": stressed and conscientious. In anime, people like Hotohori are type A's.

TYPE B-THE HUNTER
People with blood type B are the most practical of the blood groups. They are specialists in what they do. When they start a project, they spend extra time understanding and trying to follow directions than others might. When they are doing something, all of their attention is focused on it. They tend to stick to a goal and follow it through to the end, even if it seems impossible. They tend to be less than cooperative, as they like to follow their own rules and their own ideas. They are individualists. B type people pay attention to their thoughts a little more than their feelings, and therefore can sometimes seem cold and serious.
People with blood type B are often considered more relaxed, freewheeling, and unconventional than other types, although not necessarily to an unacceptable degree. In anime, the genki, off-the-wall types are type B, along with any kind of well-intended character who's ruled by their impulses.

TYPE O-THE WARRIOR
People with blood type O people are outgoing, energetic and social. They are the most flexible of the blood types. They easily start up projects but often have trouble following through because they give up easily. They are flighty and not too dependable. O types always say what's on their mind. They value the opinion of others and like to be the center of attention. Also, people with O blood are extremely self-confident.
Type O, the most "average" blood type, is considered the best type in Japan.

TYPE AB-THE HUMANIST
People with blood type AB are hard to categorize. They can have characteristics on both ends of the spectrum at the same time. For instance, they are both shy and outgoing. They easily switch from one opposite to another. AB people are trustworthy and responsible, but can't handle it when too much is asked of them. They don't mind doing favors or helping out, as long as its on their own conditions. People with this blood type are interested in art and metaphysics.
AB is considered the worst blood type. In predictability-loving Japan, they're loose cannons. They also like to set their own conditions and reserve the right to drop out when things don't meet their expectations. They're known to be sensitive and considerate—at times—but it just isn't enough to balance out the flaws in this blood type. For a while, some companies tried dividing their employees into work groups based on blood type, and no one wanted to work with the AB group. Anime villains are likely to be type AB.
-John F Kennedy
-Uchiha Sasuke, Hongo Yui, Tomo, Trowa Barton, Kenshin
A is most compatible with A and AB.
B is most compatible with B and AB.
AB is most compatible with AB, B, A, and O.
O is most compatible with O and AB.
The idea that blood type determines personality has been dying out slowly in Japan. At the same time, the West has finally noticed the potential of blood typing. We haven't quite cottoned onto the idea that blood type is related to personality, but there's a growing belief in fad diets that teach that each blood type evolved at a certain point in human history, so people with that blood type should eat the diet most common among humans at that point. Instead of balanced, nicely average O's, we have savage cavemen hunching around the fire and tearing at hunks of meat; solid-citizen type A's become "docile vegetarians" as well; bouncy type B's get to indulge in ice cream and cheese; and type AB's, as always, are half one thing and half another, and get to eat vegan food or dairy-and-everything-else—IF it suits them. Blood type diets are worth looking into if only to imagine your favorite characters' reactions to their new diets.Sailor Moon, cavewoman. That image puts me in a happy place

This site give some scientific evidence of the rationality of the above beliefs. It's cool and convincing!
But in the end, I believe that human as the highest form of living thing has utmost capacity to shape his/her personality. He has the freewill to choose to be good or bad --or both.
