The magnitude 9.0 earthquake and tsunami that struck northeast Japan on March 11, 2011, were unavoidable natural disasters, but we consider the subsequent breakdown of the Fukushima nuclear power plants to be a catastrophe made not only by nuclear engineering systems but also by avoidable system errors. This article reviews an analysis of organizational disaster which lies behind the systems pathology on the Fukushima’s problems, operating old reactors, to conceal the trouble data and the problems of supervision including non-rational location of power station. Secondly, we think about the mechanism of catastrophe from Fukushima’s case. Finally, we suggest a rational proposal concerning the fade-out of nuclear power throughout the world. These proposals are made with a view to obtain the sustainable decision-making for our future, not simply in light of the supply and demand decisions of electrical power, but also in consideration to the homeostasis of environmental aspects including the social systems based on ecosystem toward our sustainability. However,
