Japanese Culture: Blood Type Fortune Telling

What is the most popular type of fortune-telling in your country? Horoscopes? Tarot cards?
In Japan, the ABO blood type fortune-telling system is very popular.

I called it blood type “fortune-telling,” but it’s more like a statistic of personality by blood type. In conversation, someone might say, “What’s your blood type?” or “He’s type A, so he’s very responsible.” or “I want an O-type boyfriend!” We even use it as a topic of conversation with people we have just met.

It is only fortune-telling, and there is no medical evidence for it. So I personally feel that it is silly to label people by their blood type. However, it is good to know it as cultural knowledge since it often comes up in conversations with Japanese people.

If you want to know more about the ABO blood type, I recommend this American Red Cross website, which is easy to understand.
