East Japan Mega Earthquake and Dual Reconstruction Scheme-Regional and National Planning of Post-Disaster and Pre-Disaster Recovery

Abstract

Reconstruction from the Eastern Japan mega earthquake must be done as a post-disaster recovery from the affected region of eastern Japan as rapidly as possible. However, these reconstructions are not done quickly. On the other hand, the damage prevention and preparedness as a pre-disaster recoveries and reconstructions from the next Nankai trough earthquake has to be progressed steadily, because the probability of the earthquake is not low in the next three decades. The Japan has to implement the dual reconstruction scheme of post-disaster recovery in East Japan and pre-disaster recovery in West Japan, The post-disaster recovery must be done in the next 5 years, as quickly as possible. The pre-disaster recovery must be prepared simultaneously, and begin to reconstruct the Tokyo Metropolitan region and also the Pacific Ocean Cost region included with Nagoya Metropolis and Osaka Metropolis on and on. This Dual Recovery Strategy can reduce the damage of next mega-disaster and can make the resilience of both the Nation and Metropolises stronger. The Eastern Japan, the Tokyo Capital region and the Western Japan can be supported each other against the next mega-disasters.
