Biography
Chika Kuroda carved a path through the rigid academic world of early 20th-century Japan with quiet, determined brilliance. Born in Saga Prefecture, she excelled in sciences at a time when higher education for women was severely limited. Her entry into Tohoku Imperial University in 1913 was groundbreaking; three years later, she earned her degree in chemistry, a historic first for a Japanese woman. Kuroda dedicated her research life to the complex chemistry of natural pigments, meticulously isolating and determining the structures of compounds from plants like the dayflower and safflower. Her work on carthamin, the red pigment in safflower, was particularly significant, contributing to both scientific understanding and the traditional dye industry. She spent most of her career as a researcher and professor at the prestigious RIKEN institute and Ochanomizu University, not only advancing the field of organic chemistry but also mentoring the next generation of women scientists in Japan.
The Lost Generation
1883–1900
Came of age during World War I. Disillusioned by the carnage, they rejected the certainties of the Victorian era and built modernism from the wreckage — in art, literature, and politics.
Chika was born in 1884, placing them squarely in The Lost Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.

Key Achievements
- Became the first woman in Japan to receive a Bachelor of Science degree in 1916.
- Successfully isolated and determined the molecular structure of carthamin, the primary red dye in safflower.
- Served as a professor at Ochanomizu University, a former women's higher normal school.
- Her research on the blue pigment of the dayflower (commelina communis) was foundational in the study of anthocyanins.
Did You Know?
The purple pigment she discovered in the dayflower is named 'commelinin' after the plant's genus.
She was the second woman in Japan to receive a doctorate in science, after Kono Yasui.
Kuroda never married and devoted her entire life to scientific research.
