Tsujimoto graduated from Tokyo University with a degree in chemical engineering in 1901 and then went to Tokyo State Chemical Industry Research Institute.

He was mainly concerned with lipids . In 1906 he isolated the highly unsaturated hydrocarbon squalene from the liver of sharks. He recognized it as a hydrocarbon, determined the correct molecular formula C 30 H 50 and suggested the name squalene in 1916, after the Squalidae (from squalus , Latin for shark) from which he had obtained squalene.

Tsujimoto was on tour in the Japanese Alps with the Japanese Alpine Club ; Photographs taken by him serve as examples of historical photographs.
