About 40% of the Japanese population is type A and 30% are type O, whilst only 20% are type B,with AB accounting for the remaining 10%.

Four books describing the different blood groups characteristics became a huge publishing sensation, selling more than 5 million copies.

Morning television shows, newspapers and magazines often publish blood type horoscopes and discuss relationship compatibility. Many dating agencies cater to blood types, and popular anime(animations), manga(comics) and video games often mention a character's blood type.

" Being the same is considered a good thing here in Japanese society."

But we enjoy finding little differences that distinguish people. On the other hand, it can also lead to bad things being said about the minority B and AB types.

It was only in 1901 that the ABO blood group system was discovered by the Austrian scientist Karl Landsteiner. His Nobel prize-winning work made it possible to identify the different blood groups, paving the way for transfusions to be carried out safely.

It was also adopted by Japan's militarist government in the 1930s to train better soldiers, and during World War Ⅱ, The Imperial Army is reported to have formed battle groups according to blood type.

In 1990 the Asahi Daily newspaper reported that Mitsubishi Electronics had announced the creation of a team composed entirely of AB workers, thanks to "their ability to make plans".

In the Western World, O and A types make up almost 85% of people, but in India and Asia, B types predominate.

(。◕‿◕。) I don't think that personality are four patterns by blood type around the world, and also same blood type is same personality. BUT We don't know why the personality analysis by blood type make us consent.
