Based on the observed data for 27 years from 1986 at Hazaki Oceanographical Research Station, the changes of cross-shore profile and the mean sediment diameter at beach surface by huge storms have been extracted. As results, the longshore bar disappears by storm and high waves come to reach the shore. Therefore, the newly formed bar comes to be eroded easily and fine sand cannot stay near the shoreline. On the assumption that the storm is made huge by global warming, it is expected that the former beach slope becomes steep and the grain diameter near the shoreline roughens.
