The authors evaluate the statistical properties of winds and waves in smooth water areas established around Japan. Numerical predicted wind and wave data are homogeneous in time and space and the statistical properties are evaluated by analyzing the data over a long period of 10 years. In this paper, smooth water areas established in Sea of Japan and Sanriku Coast, the characteristics of those areas affected by topography are shown by the evaluating mean values, exceedance probabilities and comparison among the these sea areas.
