After 3.11 Earthquake and Tsumani Disaster, for 5 years, we have been observing and
image-recording the reconstructions of land-defense as the recovery processes at the disaster places.
They are planned as the National Land Resilience Plan. In this plan software-resilience has been
emphasized along with the hardware reconstruction of great seawalls. We discuss the role of the
software resilience as the disaster reduction manner from the view of our hardware reconstruction
records, and the coordination of the software-hardware cooperative defenses. Then, we emphasize
the system of systems approach for the planning and realizing the disaster-free societies by suitably
combining the software and hardware resiliences.
