Abstract
<p> Future projection of wave climate around Japan using high resolution wave model was conducted. Climatology of significant wave heights and mean wave periods around Japan would be decreased in the future climate by 10% and 3%, respectively. Temporal average of wave spectra was analyzed in addition to the bulk wave parameters. Energy decreases all over frequency-direction domain lead to decreases in climatology of wave heights and periods around Japan. In the Japan Sea side, the larger magnitude of energy decreases at clock-wise direction of mean wave direction causes the future anti-clock wise changes in mean wave direction by 3.5◦ . In the Pacific side of east Japan, mean wave direction would be changed clock-wise by 4.5◦ because of future energy decreases at the peak of mean wave spectra. Future changes in wave height, period and direction can be discussed consistently owing to analysis on the mean wave spectra.</p>
