Masahiko Nomi used to be a Tokyo University student who developed the blood type personality theory. His first book, Understanding Affinity by Blood Type was a 1970s bestseller. South Korea and Taiwan in Asia now use the idea. What does this mean?

Let’s check if your blood type matches your personality.


According to a Korean chart, A people are diplomatic and friendly. They like to be alone and may feel uncomfortable in crowds or events. Their hearts are weak and easily injured. Therefore they take time to trust. Others may assume they are snobs since persons with A are skilled at disguising their sentiments and don’t talk about them much. Getting to know someone with Blood Type A takes time and patience. They’re nice and down-to-earth once you get to know them. They’re always on time and strive for excellence. So, people think they’re perfectionists.


B kinds are the most extroverted, according to a Korean chart. They’re independent and care about their interests. Type Bs are continuously looking for new things to do and are confident. They express what they think regardless of the other person’s feelings, so you might assume they’re self-centered.

Blood type B men have a negative reputation in Korea since they’re considered playboys. Don’t worry; B isn’t just for playboys, despite its importance. B people are interested, honest, and prefer to be the focus of attention.
