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.

This study investigates how different segments of the public, with varying degrees of interest in S&T, could formulate opinions on a broader vision and the role they think STI should play in Japanese society through 2020 (Tokyo's Olympic and Paralympic year) and toward 2030. We conducted nine inclusive public engagement activities. Results indicated that the broad public opinions did not completely overlap with officials' opinions, a value of “open and appropriate” was mainly found from the unengaged public, and the visions and values based on their opinions could well be incorporated into the official document. Engaging the disinterested in S&T remains an issue.

This paper is a reflective account of a public participation project the authors conducted in Japan in 2012–2015, as part of the central government's initiative for evidence-based policy-making. The reflection focusses on three key aspects of the project: setting a precedent of involving public participation in policy-making; embedding an official mechanism for public participation in policy-making process; and raising policy practitioners' awareness of public participation. We also discuss why we think engaging with policy practitioners, while problematic in various ways, is and will continue to be important in promoting institutionalised practice of public participation.

Currently, science is developing rapidly and its influence on society is more significant than ever. This is all the more reason for today’s scientists to interact with the general public. To design effective science communication activities, we must understand scientists’ motivations and barriers to publicly communicating science. In this study, we interviewed 19 early-career scientists who had participated in science cafes in Japan. From these interviews, we identified five factors leading to their reluctance to participate in science cafes: 1) troublesome or time-consuming; 2) pressure to be an appropriate science representative; 3) outside the scope of their work; 4) could not perceive any benefit; and 5) apprehension about dialogue with the public. Among these factors, apprehension about dialogue may be the clearest reflection of the scientists’ underlying feelings about this form of communication and an indicator of more intrinsic barriers to engaging in science cafes.
