The purpose of this paper is to estimate alongshore distribution of maximum wave height around the Japanese coast generated by long-term typhoons through wave hindcasting based on a spectral wave prediction model. First, the applicability of the model to the evaluation of typhoon-generated waves is confirmed from the comparison between hindcasted results and wave data observed during many typhoons in recent years. Second, based on the wave hindcasting for 120 typhoons which attacked Japan in the past 50 years, alongshore distribution of maximum wave heights and their occurrence probability are estimated and compared with that of design wave heights of coastal structures. It is deduced that the design wave heights in the western district of Japan seem to be slightly small for probable maximum wave heights.
