Can blood type really determine your personality and have an influence on relationships and workplace dynamics? The Japanese think so.
When visiting Japan, you may hear conversations centred around the unusual topic of blood type. The Japanese are fascinated by a person’s blood type and a theoretical connection to personality traits, or ketsuekigata. This unique cultural phenomenon, although not scientifically supported, is a widespread belief among the Japanese and originated in 1927 from a paper by Japanese professor Takeji Furukawa. He proposed how people with different blood types exhibit distinct personality traits. His work gained popularity over time and by the 1970s, blood type personality theories were solidified in Japanese pop culture. Even today, blood type has influence on personal and professional relationships. Take a look at what the Japanese believe about blood type and personality.
The Four Blood Types
The Japanese believe each blood type is associated with specific characteristics. The principles behind the theory are so ingrained in Japanese society that people often discuss blood type as casually as astrological signs. Below is a brief overview of the blood types, or read a detailed account here.
Type A: Type A people are typically conscientious, responsible and pay attention to details. They are considered perfectionists who value order, plus are reserved or introverted. In stereotypical portrayals, they are shown as overly anxious or stressed.
Type B: Blood type Bs are regarded as free-spirited and the most likely to be creative and individualistic. They are portrayed as passionate and fun-loving yet viewed as selfish or unpredictable.
Type AB: Type AB individuals are considered complex, adaptable, and balanced. They are thought to have a mix of both A and B traits, making them sometimes seen as unpredictable or difficult to understand. Whilst intellectual and philosophical, they may also be detached or aloof.
Type O: Type O people are confident, outgoing, and strong-willed. They are thought of as natural leaders with a positive attitude, though they can also be viewed as arrogant or overly ambitious.
