The theory was first introduced to Japan in 1916 by Dr Kobayashi Sakae(小林栄) and Hara 来復 (原来復). Their mythology was made up from non-statistical basis. He learned blood type mythology in Germany. Once used as evidence in contrary to Takeji Furukawa's mythology,

In 1926 Rin Hirano and Tomita Yashima published the mythology "Blood type biological related" in the medical journal of army. It was the non-statistical and unscientific report, just as those previous ones, made up with the racism.

In 1927, Takeji Furukawa, a professor at Tokyo Women's Teacher's School, published his paper "The Study of Temperament Through Blood Type" in the scholarly journal Psychological Research. The idea quickly took off with the Japanese public despite his lack of credentials, and the militarist government of the time commissioned a study aimed at breeding the soldiers. The study used no more than ten to twenty people for the investigation.

In another study, Furukawa compared the distribution of blood types among two different ethnic groups, the Formosans in Taiwan and the Ainu

, the inhabitants tenaciously resisted their occupiers. Insurgencies in 1930 and in 1931 killed hundreds of Japanese settlers.

The purpose of Furukawa's studies was to "penetrate the essence of the racial traits of the Taiwanese, who recently revolted and behaved so cruelly". Based on the finding that 41.2% of a Taiwanese sample had type O blood, he assumed that their rebelliousness was genetically determined. The reasoning was supported by the fact that among the Ainu, whose temperament was characterized as submissive, only 23.8% had type O. In conclusion, Furukawa suggested that the Taiwanese should intermarry more with the Japanese in order to reduce the number of individuals with type O blood.

The fad faded in the 1930s as its unscientific basis became evident. It was revived in the 1970s with a book by Masahiko Nomi
