Academic career
When Yasui applied to the Japanese Ministry of Education to study abroad, they were hesitant to give her permission because of their belief that “a woman cannot achieve much in science.” She was only allowed on the condition that she listed "home economics research" alongside "scientific research" on her application and that she agreed not to marry and instead commit herself to her research.

Most notably, she was the first Japanese woman to receive a doctoral degree in science, and she did so at a university that did not accept female students until almost 20 years later.
