Career
Katsusaburo Yamagiwa became an appointed assistant professor of his alma mater in 1891. In 1892, he proceeded to Germany and studied under Professor Virchou. In 1894, he returned home and the following year became a professor of Tokyo University. He served in this post for more than 39 years, till his retirement due to age limit. Also served as a visiting professor of Naval Staff Officers' College. In 1984, he also attended International Medical Conference in Italy. In the same year he proceeded to Formosa to study parasites.

The 1926 Nobel Prize went to Johannes Andreas Grib Fibiger, for his discovery of Spiroptera carcinoma, a microbial parasite which Fibiger claimed was the cause of cancer. This "finding" was discredited by other scientists shortly thereafter.Two years later, Katsusaburo Yamagiwa successfully induced squamous cell carcinoma by painting crude coal tar on the inner surface of rabbits' ears. Yamagiwa's work has become the primary basis for this line of research.Because of this, some people consider Fibiger's Nobel Prize to be undeserved, particularly because Yamagiwa never received the prize for his work.
In Japan, some documents pointed out to the Nobel committee claim that they made an error due to their white supremacy beliefs. In 1966, the former committee member Folke Henschen strongly advocated that Dr. Yamagiwa deserved the Nobel Prize, but unfortunately it was not realised.
