Google honours Michiyo with a doodle and has shared a glimpse of her journey through a perfect post. Michiyo was born in 1888 in Okegawa, Japan. She started her career teaching science. In 1920, she became a scientific researcher at Hokkaido Imperial University where she began to analyse the nutritional properties of Japanese silkworms. 

In Tokyo Imperial University, Michiyo with her colleague Umetaro Suzuki conducted research on green tea. In 1929, she was able to isolate a bitter ingredient of tea called catechin, and later she was also able to isolate an even bitter compound tannin. 

Later, Michiyo went on to become the first Dean of the Faculty of Home Economics at Tokyo Women’s Higher Normal School in 1950. Today, a stone memorial in honour of her achievements can be found in Okegawa City.
