This study is a subsequent paper of research on housing reconstruction action by self-help relocated survivors after the Great East Japan Earthquake which examines a half decade process of decision making and degree of satisfaction and its relevant factors. The methodology of the study is questionnaire survey in 2016 for tsunami-affected 9 municipalities along the coast in Iwate and Miyagi prefecture (n=823 respondents).
Their motivation is quick housing reconstruction in the place where they can achieve a secure feeling. It is proved that government-driven urban redevelopment project pursuing “safety” hasn't provided “secured” place for survivors to restart their life. The motivation of residents who designated as outside hazardous zone is strongly affected by their household attribution when compared to inside the zone. This implies that government-driven urban redevelopment project hasn't worked as exclusive driving force to implement the image of the city stated by the post-disaster recovery plan, but an appropriate speed of the project might have controlled the location of peoples' habitation.
The timing of decision-making, the motivation inside hazardous zone, their subjective advantage/disadvantage, and the degree of satisfaction are all affected by the positive decision-making for self-help individual relocation. Self-directed decision-making increases the level of satisfaction.
