We believe that a society where no one is left behind, which is the goal of the SDGs, is a society that we should strive for even in the event of a disaster. Therefore, we research the mechanism of support based on coordination among government, public support organizations such as DMAT, DPAT, DWAT, NGOs, and voluntary disaster management organizations as partners in health, medicine, public health, and welfare. In particular, we collaborate with many stakeholders to research understanding public mental health in times of disaster, developing human resources who can provide support without harming those they support or themselves, and protecting children, one of the vulnerable groups to protect in times of disaster.
