The coastal area in the Tohoku region of Japan suffered serious damage from the tsunami caused by the Great East Japan Earthquake in 2011. The purpose of this research is to develop a simulator in order to predict potential damage and put in place disaster prevention measures to protect railway structures against such large scale tsunamis. For this research, a simulation was made of the tsunami generated by the Great East Japan Earthquake to evaluate the damage process that occurred at Shishiorikarakuwa station in Kesennuma city. The tsunami simulator involves a three stage zoom analysis covering a large area from the epicenter to the urban area. The results of the tsunami simulation were then used to conduct a structural analysis of the Shishiorikarakuwa station subject to the tsunami fluid pressure.
