Open Science practices in Japan: What is the next step towards data stewardship?

The purpose of this study is to reveal the current state of Open Science practices by researchers in Japan. Therefore, online questionnaire surveys were conducted in 2016 and 2018. The surveys were conducted on researchers registered in the Network of Science and Technology Experts managed by the National Institute of Science and Technology Policy (NISTEP). The Network is a group consisting of approximately 2,000 specialists such as researchers, engineers, and managers of industry, university, and government, who collect trends and opinions on science and technology.
