The Research Center on Ethical, Legal, and Social Issues (ELSI) at Osaka University and mercari R4D started a practical joint research project in 2021 to innovate based on the concept of ELSI and responsible research and innovation (RRI). This paper describes the research and practice conducted in this joint project on (A) upgrading the ethics review process for research and development, (B) assessing AI-based solution technologies and strengthening AI governance, and (C) conducting a feasibility study for participatory technology assessment on quantum technology, respectively. In this paper, we illustrate the methods and processes of this project, as well as the results of these individual studies, and share critical reflections on the ELSI/RRI knowledge production processes from the perspectives of both ELSI researchers and members of the private sector. Our results provide evidence of the contribution to innovation governance in science and technology from ELSI/RRI research and the knowledge of the humanities and social sciences.
