In this paper, the characteristics of the tsunami due to Nankaido earthquake and moored ship motions were investigated numerically. Tsunami simulation was carried out by using shallow water wave theory and moored ship motions were evaluated by strip method. The traveling time of the tsunami that from hypocenter to Kobe port was about 2 hours, and tsunami current was parallel to normal direction of quay walls. The moored ship was oscillated several meters to surge and sway direction by incident of tsunami. Reaction force of fenders where located near stem and stern were increased by yaw. Such influence of the tsunami on moored ships to quay walls and countermeasures against tsunami disasters were estimated.
