Abstract
Recent increase of natural disasters in Japan including those by earthquakes is surprising. Among two hundred thousand of people died from the East Japan Earthquake, the rate of the elderly is quite high and demonstrated the lack of the infrastructure construction. Additionally, prolonged poor living conditions as evacuees increase the disaster-associated mortality, which reveals the importance of the care after disasters. This study seeks to improve the survival rate of vulnerable people, such as patients in care facilities, on large-scale earthquake disaster through the sentiment survey from the caregivers and the prioritization of the BCP development. This is an early study to develop infrastructure based on the mutual self-help, being different from the public help which the government is considering.
