Blood Type and Personality: Myth or Reality?

A remarkable phenomenon is observed in modern Japan: the national obsession with the connection between blood type and personality has reached unprecedented levels. A whole industry of "blood predictions" flourishes in the country - from detailed horoscopes to specialized job vacancies. This phenomenon has penetrated society so deeply that it has become an integral part of Japanese daily life.

How did this theory emerge?

The origin of this unusual belief occurred in the first half of the last century. Japanese scientist Takeji Furukawa proposed a revolutionary idea in 1927, suggesting a direct connection between blood and personality. The theory experienced a real boom in the 1970s when journalist Masahiko Nomi transformed the scientific hypothesis into a mass phenomenon, comparable in popularity to traditional astrological predictions.

Impact on Japanese culture

In modern Japan, blood type is used as a universal criterion for:
✅ Making compatibility predictions in personal relationships

This belief has become so deeply rooted that even anime and manga creators consider blood type when developing character personalities.

Science or myth?
