The primary aim of this textbook is to contribute towards the promotion of human security by educating nurses with a profound understanding of disaster nursing and to conduct innovative research and practices in cooperation. This textbook emphasizes on multi-professional connections; offers knowledge on how Japanese disaster nursing got evolved in changing social contexts and provides various case studies that reflect wonderful practices in the disaster nursing field which have contributed to the Sendai Framework for Disaster Risk Reduction, the UN Sustainable Development Goals, and sustainable human security. Frequent disasters have triggered the need for more trans-disciplinary work, high-level care throughout all phases of a disaster event, and the need for nursing leaders. Apart from hospitals, in local communities, nurses can take a role to mitigate health risks.
