Blood types (血液型)

In the West people often refer to one's astrological sign to understand some character traits. In Japan such an indicator is one's blood type, ketsuekigata (血液型)! That is why it is common for people to ask for your blood type in Japan、and it is surprising for a Japanese person that someone does not know their blood type.

It is popular for famous people to include blood type information on their web pages, or for baseball players to have it included on collectors cards. Creators of manga and anime often include the information about the character's blood type when introducing the story, and in such way determine certain traits of their personality.

It is interesting, that only Korean and Japanese Facebook allows the blood type information in the user profile!
