A wave hindcast system, which consists of ECMWF wind data sets over a period of 20 years from 1979 to 1998 and a shallow water wave model based on a backward ray tracing, is applied to the estimation of long-term waves at measurement stations deployed around the coastal areas of Japan. Comparison between the 2-3 hourly measurements and hindcasts is made for the time series of waves, the wave climate parameters of each month or over the whole period, their climatic change and extreme wave heights. The main finding is that the system is very useful not only for a proper evaluation of the wave climate and its interannual change but also for estimation of the return wave height with confidence interval at coastal locations around Japan directly facing the open sea, particularly the Japan Sea coast.
