Michiyo Tsujimura graduated from Tokyo Prefecture Women’s Normal School in 1909 and went on to Tokyo Women’s Higher Normal School’s Division of Biochemical Science. Tsujimura learned from the biologist Kono Yasui there, who sparked her interest in a scientific investigation.

After earning her degree in 1913, she started working as a teacher at Yokohama High School for Women in Kanagawa Prefecture.

Career and Professional Life

Michiyo Tsujimura joined Hokkaido Imperial University in 1920 as a laboratory assistant, which marked the beginning of her research career. Tsujimura held an unpaid post at the university’s Agricultural Chemistry Department’s Food Nutritional Laboratory because at the time the institution did not accept female students.

Therefore, before moving on to the Medical Chemical Laboratory at the Medical College of Tokyo Imperial University in 1922, she conducted research on the nutrition of silkworms there.

Tsujimura transferred to RIKEN as a research student in October 1923 after the September 1923 Great Kant earthquake devastated the laboratory. She conducted nutritional chemistry research with Umetaro Suzuki, a doctor in the agriculture lab.

In 1924, Tsujimura and Seitaro Miura published a paper titled “On Vitamin C in Green Tea” in the journal Bioscience, Biotechnology, and Biochemistry detailing their discovery that green tea contains vitamin C. The export of green tea to North America increased as a result of this discovery. In 1929, Tsujimura extracted flavonoid catechin from green tea.

In 1930, Tsujimura used green tea to crystallize tannin. She received a doctorate in agriculture from Tokyo Imperial University in 1932 for her thesis on the chemical components of green tea, making her the first woman in Japan to do so. The title of her dissertation was “On the Chemical Components of Green Tea.”

In 1934, she isolated gallocatechin from green tea, and in 1935, she filed for a patent on her process for obtaining vitamin C crystals from plants. She started at RIKEN as a junior researcher in 1942, was promoted to a researcher in 1947, and was finally made a professor in 1949, the year Ochanomizu University was established.

Tsujimura began teaching there in 1950 and served as the institution’s first dean of the Faculty of Home Economics. In 1955, Tsujimura retired from Ochanomizu University as a professor, but she kept giving occasional lectures until 1961. She taught at Tokyo’s Jissen Women’s University from 1955 until 1963, when she became a professor emeritus.
