Masahiko Nomi was born in 1924.(-1981)
He graduated from Tokyo University's Department of Engineering.
Nomi began his writing career by becoming Japan's first radio scriptwriter while still at Tokyo University. He also proved to be an excellent Sumo commentator.

Nomi's interest in the connection between blood type and human disposition was aroused by his elder sister while he was a high school student. His sister showed him the chart which you see below.

"Blood type and human character can be related somehow. This chart shows the relationship between blood type and interpersonal compatibility."

Although the source of the chart is uncertain, Nomi's sister could have made the original herself.

After that, Nomi kept his eye on people in every human relationship, including family, friends, business, etc., in order to observe them through his specific lens - blood type.
His occupation as a writer, combined with his openhearted personality, endowed him with numerous acquaintances. This helped him greatly in developing his powers of observation of the human being.

Nomi continued observing people by blood type for thirty years. In 1971, he decided to publish a book about the links between blood type and human disposition based on his observations. He believed his theory was correct, although he had some concerns. To his surprise, the book created an even greater sensation than he had expected. Convinced of his theory by this success, he commenced formal research and study, through which he collected up to 100,000 items of research data, including the blood types of specialists from various fields, questionnaires and statistical analyses. The link between blood type and human disposition indicated by all of these research results was so strong that even Nomi himself was astonished. He called this research "Blood Type Humanics" and proposed that it be developed as a new scientific field.

After Masahiko Nomi died, his son, who had assisted him as both a secretary and a student in the field, succeeded him in his work. Now, pursuant to his father's will, Toshitaka Nomi is actively spreading this study among the population. It is our ambition to spread Blood Type Humanics throughout the world.
