The Great East Japan Earthquake that occurred on March 11, 2011 brought about enormous damage. After that, we paid attention disaster remnants through media and others immediately. However, disaster waste can be disposed in order to promote restoration and reconstruction at an early
stage, so many of them were removed. A new support framework for preservation was presented by the Reconstruction Agency, but it may become once and for all. For this reason, the establishment of a system to preserve them is still insufficient. Therefore, it is necessary to consider effective means for preservation and disclosure method of the disaster remnants. We must examine ways that can be reflected in various disasters. In this study, we can see that active preservation such as value evaluation
of disaster remnants by the committees play a big role in preserving them. In addition, it is effective to do temporary preservation and avoid to make hasty decision.
