U.S. and other publics perceive STEM (science, technology, engineering, and mathematics) fields as masculine and scientist as a male occupation, but Japanese public perception remains unstudied. Using an online survey, we identified keywords associated with physics, chemistry, mechanical engineering, information science, biology, and mathematics. A second online survey showed that the Japanese public perceived both keywords and fields as masculine. This trend was stronger in individuals with less egalitarian attitudes towards gender roles. We suggest that attitude towards gender roles contributes to the masculine image of science in Japan.

Many studies have examined the impression that the general public has of science and how this can prevent girls from choosing science fields. Using an online questionnaire, we investigated whether the public perception of several academic fields was gender-biased in Japan. First, we found the gender-bias gap in public perceptions was largest in nursing and mechanical engineering. Second, people who have a low level of egalitarian attitudes toward gender roles perceived that nursing was suitable for women. Third, people who have a low level of egalitarian attitudes perceived that many STEM fields are suitable for men. This suggests that gender-biased perceptions toward academic fields can still be found in Japan.
