Is it true that there is discrimination based on blood type in Japan?
Yes.
The Japanese pay a lot of attention to a person's blood type, believing that it determines one's character.
Those who have the first type are ascribed decisiveness and self-confidence, the second group is considered reliable and reserved, the third group is considered intelligent and ambitious, and the fourth group is considered balanced, rational, and demanding.
For many Japanese, blood type is one of the criteria for choosing a dating partner, and for employers it can be an additional factor in approving or rejecting an applicant.
