The “open-seminar” is a research meeting within RISH during lunchtime on Wednesdays. At each seminar, we invite a lecturer from RISH or outside with the aim of sharing results within RISH, inspiring new seeds of research, and enhancing collaborations. We held 12 open seminars in FY2020 with a total of 586 participants. By holding the seminar online, the number of participants nearly doubled from previous years and we were able to have seminars delivered from remote cities such as Hokkaido and Seattle. In association with our international promotion program, “RISH Asia Research Node”, we also delivered 8 seminars across the world through the internet to the Indonesian Institute of Science (LIPI).
