To many Japanese, the key to their personality lies not in their stars but in their blood type. Speaking broadly, it is said that people with Type A Blood are calm, composed, and very level-headed and serious. People with Type B Blood are curious about and interested in everything. Type O Blood people are said to set the mood for a group and to take on the role of creating harmony among its members. People with Type AB Blood are said to have a delicate sensitivity. They are considerate of other people’s feelings and deal with them with care and caution.

In Japan, blood type has influenced peoples lives in unexpected ways. For instance, some Japanese companies have planned departments around the blood types of their workforce. This is why this myth is nowadays under attack.
