Tsujimura was born in 1888 in Saitama Prefecture. After working at Jinjo Higher Elementary School as an assistant teacher, she then studied at Tokyo Prefecture Women’s Normal School, and later Tokyo Women’s Higher Normal School. At Tokyo Women’s Higher Normal School she studied under Kono Yasui and developed a strong interest in a life of scientific research. After graduating she worked as a teacher for seven years in Kanagawa Prefecture and Saitama Prefecture, then began a career as a researcher.
Hokkaido Imperial University, the school her professors recommended her to, did not accept women students at the time, so Tsujimura acquired a post in the Food Nutritional Laboratory of the Agricultural Chemistry Department as an unpaid assistant.
