The 2011 Great East Japan earthquake has shown all too clearly that disaster management and mitigation measures seen from the viewpoint of protecting society are not sufficient for addressing a national crisis such as the projected Nankai Trough earthquake or Tokyo inland earthquake whose damage is expected to exceed the present estimated damage. Our study explores the weakness against disasters in how modern Japanese society uses “reverse thinking” in which investigates studying how large-scale disasters may adversely affect society and increase damage effectively. This process profiles the worst disaster scenarios that could conceivably lead to a national crisis. Classifying these worst scenarios, we suggest policies to the problems that are common to many scenarios, and we present action plans for individual problems. First, we conduct workshops for identifying damage magnification factors and evaluating their importance under the categories of human damage, property damage, and damage to social functions, unifying the awareness of research organization. Second, we have researchers on 1) mortality, 2) tsunami inundation, 3) liquefaction, 4) capital function, 5) evacuation, 6) required assistance, 7) lifelines, 8) high buildings, 9) information networks, 10) government systems, and 11) economic systems analyze damage magnification conditions due to hazard, vulnerability and measure aspects. Third, we sort potential final consequences and separate them based on commonality, and propose new policies and concrete action plans for preventing the occurrence of worst-case scenarios. This research is expected to give new paradigms in disaster management science and new ways of policy making and action planning that will minimize the undesirable consequences of catastrophic earthquake and tsunami and yield new knowledge on disaster processes and damage magnification scenarios. Most importantly, we conclude that it is necessary to have a new Japanese governmental organization, such as a Ministry of Disaster Resilience or a Disaster Resilience Management Agency, handle these national crises.
