People often wonder why on profiles of Japanese characters in anime, movies, and television in addition to listing name and age, often blood type is mentioned as well. In Japan, if you get to know someone well, chances are high they will ask you what your blood type is. The reason for this is many people believe that blood types are associated with personality (kind of like the horoscope), and compatibility with other people. The general “personalities” associated with blood types is as follows:
A Blood Type
Perfectionist, punctual, shy, intellectual, patient, pigheaded
B Blood Type

O Blood Type

AB Blood Type

And here are the compatibilities associated with the blood types:
A is compatible with A and AB
B is compatible with B and AB
AB is compatible with AB, B, A, and O
O is compatible with O and AB.
Interesting note: about 40% of the Japanese population have B blood type.
