If you have ever visited Korea or stayed in Korea for quite some time, you have probably noticed that a lot of Korean people ask “what is your blood type?”. This question is one of the most common questions that Korean people ask, apart from “How old are you?”. In Korea, it is perfectly fine to ask about a person’s blood type, especially if you want to get to know someone very well instantly, in particular, on a blind date. The reason is that Korean people believe that each blood type has its own distinct personality and it is the quickest way to determine a person’s temperament and even compatibility with others. You may feel confused as to why people ask about blood types in Korea, but don’t worry. If you are asked this by a Korean, that means that the person wants to get to know you better.

So who developed this concept? The blood type personality theory was developed by a Japanese person named Masahiko Nomi who graduated from the University of Tokyo. He began his first career as a journalist and his first book “Understanding Affinity by Blood Type” became a bestseller in the 1970s. The idea then spread outward and it is popular in some Asian countries, such as South Korea and Taiwan. You are probably wondering, ‘so what’s this all about?’, so let’s have a look at the description of each blood type to see if it matches with your personality. Then let’s look at the compatibility of blood types, followed by the blood types of famous Korean celebrities.
