Since the Great Hanshin-Awaji Earthquake, Japan Self-defense Force (JSDF)’s disaster relief activity has been widely recognized as essential disaster relief tools for affected society. This behavior is strengthened after The Great East Japan Earthquake. Since the beginning of 2019, JSDF tries to introduce “proposed-style” disaster relief activity: disaster relief activity SDF units actively analyze the impact and situation of the damage and propose its disaster relief activity to disaster-affected local authority. Based on the situation, this paper tries to perceive character of current SDF’s disaster relief action quantitively with published briefs about individual disaster relief activity from 2006 to 2018 and consider these data with Disaster Research Center Typology (DRC-Typology). As conclusion, this paper points out importance of compiling criteria for setting of Joint Task Force and multilateral coordination for apportioning role for needs of disaster affected society between, local authorities, SDFs and other public and private sectors.
