Since the 1990s, journals have become increasingly online and open access. In fact, about 50% of articles published in 2021 were open access. The use of preprints (i.e., non-peer-reviewed articles) has also increased. However, there is limited awareness of these concepts among academics. Therefore, we conducted a questionnaire-based survey among members of the Molecular Biology Society of Japan. The survey was conducted between September 2022 and October 2022, with 633 respondents, 500 of whom (79.0%) were faculty members. In total, 478 (76.6%) respondents had published articles as open access, and 571 (91.5%) wanted to publish their articles in open access. Although 540 (86.5%) respondents knew about preprints, only 183 (33.9%) had posted preprints before. In the open-ended section of the questionnaire survey, several comments were made about the cost burdens associated with open access and the difficulty of how academic preprints are handled. Although open access is widespread, and recognition of preprints is increasing, some issues remain that need to be addressed. Academic and institutional support, and transformative agreement may help reduce the cost burden. Guidelines for handling preprints in academia are also important for responding to changes in the research environment.
