Life
He was born on 6 June 1930. He is the great-grandson of Duke Sadahiro Mōri, the 28th head of the Mōri clan. He is also related to the Tokugawa clan through his grandmother Masako, who was a sister of Marquess Yoshichika Tokugawa, the botanist. His maternal grandmother, Ariko, was the daughter of the founder of Shiseido, Arinobu Fukuhara, and through him, he is related to the Nobel laureate in Chemistry, Ryoji Noyori.

He graduated from the University of Tokyo's Faculty of Science, Department of Zoology in 1953. His specialisation was in reproductive biology and animal physiological chemistry. He continued research on sperm at the graduate school of his alma mater and the university's Misaki Marine Biological Centre from 1968 to 1990. He elucidated the constituent proteins of the sperm flagellum's structural body (cytoskeleton). In 1968, he determined the amino acid composition of the microtubule's constituent proteins and named it tubulin. From 1987 to 1989, he served as Dean of the College of Arts and Sciences. In 1991, he retired from the University of Tokyo and was conferred the title of professor emeritus.
