To understand the characteristics of tsunami propagation in the Seto Inland Sea, tsunami simulations for the largest earthquake on the Nankai trough were conducted. In this paper, we assumed three fault models with taking into account the latest findings after the 2011 earthquake off the Pacific coast of Tohoku. For the case of large fault slip along the plate boundary region, the tsunami height around the Seto Inland Sea was about the same as the value of the conventional assumption, because the tsunami components generated by the plate boundary regions were attenuated when passing through the straits. But we confirmed that the tsunami height around the Seto Inland Sea became higher in the case of delayed rupture with appropriate time lag, or in the another case that the fault region was expanded to north.
