The objective of the General Research Group for the Nankai Trough Great Earthquake is to obtain a cross-sectional view of research on the Nankai Trough Great Earthquake, conducted by the various working groups of the Earthquake and Volcano Hazards Observation and Research Program, and to thereby promote the Program’s research in a comprehensive manner. In this paper, we report on workshops held during a five-year period (2014–2018), and summarize the findings of the five-year plan following the Research Group’s scheme. We also discuss issues that surfaced during these activities.
