Tsunami disaster prevention of Seto Inland Sea is slow to take action for lack of knowledge of generation mechanism of Tsunami damages. According to previous research papers, there is a possibility of appearance of sudden water level raising and long-term water level fluctuation in sympathetic vibration with characteristic vibration in some bay. Therefore, this study focuses on period characteristics and hazardous sea area. As a result of numerical analysis, temporal period characteristics of each sea area, distribution of largest tsunami heights and time of occurrence, distribution of maximum tsunami velocity and time of occurrence and a map of hazardous sea area are clarified. Moreover, generation mechanisms of Tsunami damages are examined.
