Abstract
In this paper, we discuss the problems of disaster prevention measures in Japan in terms of tsunami evacuation after the Great East Japan Earthquake. The three problems are pointed out.
The first problem is "estimationism" of disaster prevention countermeasures in administrative. From now on, required disaster prevention is not to put an assumption as a precondition. In most cases, it is focused disproportionately on worst-case scenario or limited to assumption. We should take the every case into consideration and think about how to act, we should create a norm of evacuation.
The second problem is "spiritualism" of tsunami evacuation. It is not easy for many people to evacuate in tsunami disaster. This is not such a problem can be solved only by preparedness and some kinds of spirit such as "Evacuation" and people's consciousness regarding disaster prevention. But regarding those problems concerned "Evacuation", spiritualism which drew a conclusion that those suffered from Tsunami are lack of sense for danger is popular. But That wouldn't be solving the problem. It is important to take not only non-structual measures but also structual measures.
The third problem is "hypothecism". Many offisicals and researchers make hypotheses under the wrong recognition of fact about tsunami evacuation made by media discourse or their preconceived opinions. We should conduct thorough survey and analysis in detail of tsunami evacuation behaviors and the other behaviors of the Great East Japan Earthquake.
We need to overcome these problems to save more people.
