Many elderly people were killed by Tsunami during Great East Japan Earthquake in Akahama, Otsuchi town, Iwate prefecture. The purpose of this paper is to describe the evacuation behaviors by interviews with residents in Akahama which is along the rias Coast and clarify how the built environment influence on the evacuation behaviors of the elderly. It is found that 1) geographical features such as nearness of a rising ground, sloping road to the sea and a narrow plain land are good for evacuation, 2) the towns background such as past tsunami, seawall construction and elementary school which has never been damaged in a few hundred years influence on evacuation behaviors and 3) family network and local community led to an influence on a turning point of an evacuation behavior, but there were younger people who tried to help the elderly and damaged or killed.
