Heijiro Nakayama

Heijiro Nakayama was born in 1871 in Kyoto City to a family of physicians. In 1874, he moved to Tokyo. During secondary school days, he was interested in archaeology and found remains, possibly, Yayoi pottery. He graduated from the Faculty of Medicine, Tokyo Imperial University and studied in Germany between 1903 and 1906. In the same ship was Sunao Tawara, also a pathologist. Nakayama became Professor of Pathology, Kyushu Medical University of Kyoto Imperial University, now Kyushu University at age 35. Nakayama's elder brother, Morihiko Nakayama served as Professor of Surgery at the same school. Nakayama's students included a Chinese physician Guo Moruo and Hakaru Hashimoto. Hashimoto thanked Nakayama for his guidance in his paper which led to the name of Hashimoto's thyroiditis. Nakayama studied the life cycle of Schistosoma japonicum.

In 1909, he was accidentally infected with pyogenic bacteria during an autopsy, but fortunately survived. Since then, he completely discontinued pathological studies and started archaeology. Sunao Tawara, Professor of Pathology, pathologist of another department of Kyushu University undertook pathological studies.

During the Taishō era (1912-1926), he exclusively wrote in Kohkogaku zasshi (Jpn J Archaeology), and he was criticized that he monopolized this journal, although this journal was open nationwide. In the early years of the Showa era, upon hearing the criticism, he discontinued his studies and turned to angling near his home, along the Hakata Bay. After the war, he taught archaeology to Dairoku Harada upon his return from military service.
