Thanks to his groundbreaking research, science today has the answer to why green tea tastes so bitter when steeped for too long.

Born on this day in 1888 in Okegawa, Saitama Prefecture, Japan, Sujimura spent her early career teaching science. In 1920, he pursued his dream of becoming a scientific researcher at Hokkaido Imperial University, where he began analyzing the nutritional properties of the Japanese silkworm.

A few years later, Tsujimura transferred to Tokyo Imperial University and began researching the biochemistry of green tea with Dr. Umetaro Suzuki, who was famous for his discovery of vitamin B1. Their joint research showed that green tea contained significant amounts of vitamin C – the first of several unknown molecular compounds in green tea that awaited under the microscope. In 1929, he isolated catechins – a bitter component of tea.

Then, the next year he isolated tannins, an even more bitter compound. These findings laid the foundation for her doctoral thesis, "On the Chemical Components of Green Tea", when she graduated in 1932 as Japan's first female doctor of agriculture.

In addition to her research, Dr. Tsujimura also made history as an educator when she became the first dean of the Faculty of Home Economics at Tokyo Women's Higher Normal School in 1950. Today, a stone monument in honor of Dr. Tsujimura's achievements can be found in his birthplace of Okegawa City.
