What blood type is dominant in Japan?
This article explores the different blood types in Japan, how O-type is the most common type of blood and why, and how blood typing is used in Japanese culture. It also explains the ABO and Rh blood group systems, which are used to categorize people into four major groups (A, B, AB, and O) and two main categories (positive (+) and negative (-)). O-type is the most common due to its compatibility with all other types, lack of adverse reactions, as well as its use for determining compatibility between potential partners, friends or employers. This topic has become popular within Japanese culture due to its prevalence in popular media such as manga comics and anime series.
