Basic features of coastal evolution on Chirihama Beach, Japan, have been investigated using a set of field surveys. The results on the shoreline survey show long-term eroding trend during the last twenty years. The cross-shore profile survey records show that the seabed slope has been decreasing more recently. The typical profile configurations are characterized by the presence of multiple bars. An EOF analysis has been conducted on the periodic movements of these bars. The net offshore migrations of bars have been repeated with a return period of approximately 4 years. It is also shown that the transition from double bar to triple bar configuration accompanies the temporal retreat of shoreline. The alongshore variability of the behavior of multiple bar system has also been examined.
