Blood Typing Chart: History

Generally, Japanese people use blood types, like star signs and MBTI, to examine people’s strengths and weaknesses. Furukawa Takeji, a Tokyo Women’s Teacher’s School professor, first theorized about blood types and personality in 1931.

Accordingly, his theory said that temperamental differences between student applicants are related to their blood type. The academic field considered his research controversial due to insufficient scientific proof.

Despite the controversial research, his work influenced others, such as Masahiko Nomi. Masahiko Nomi, a journalist who published several books about blood types that are still popular today, with some books selling over 5 million copies!

Blood type personalities are ketsueki-gata in Japanese. Ketsueki-gata takes the core concepts of Furukawa Takeji to a whole new level because it teaches us about compatibility, strengths, and weaknesses.

Type O

According to ketsueki-gata, if your blood type is O, you are a natural-born leader. People feel your presence when you call and a room, and you’re able to influence their energy! The Japanese word for such bright people is rakkanshugi.
