The purpose of this study is to examine how much the existence of the coastal forest influenced the grade
of the house damage caused by the 2011 off the Pacific coast of Tohoku Earthquake tsunami. The research methods consisted of a geographic survey and damage grade investigations of the building by a foundation survey and aerial photos. A comparison of the area which had the coastal forest in the coast and the area which didn't have it revealed that the level in both areas were flat and the height from sea level and the height of the tsunami were the same, however the damage caused to buildings differed. Thus, the mitigating effects of the coastal forest against the tsunami were examined. The ratio of complete collapse in the area as the coastal forest where the distance from the coast was same was high. Therefore, it has been interpreted as existence of the coastal forest having prevented the damage of the building, and generating of rubble. And it is an important consideration matter in the plan of the development and maintenance of the coastal forest and the overall community including the coastal forest that the damage of the building at the side end of the coastal forest was serious
