Chirihama Beach, where drivers are allowed to drive their cars over the sand beach, is an important site for tourism. However, since the 1980s, the area has been actively eroded and the shoreline is reported to have receded by approximately 50 meters. This report reviews the characteristics of the littoral drift of the Chirihama Beach based on a field survey of the shoreline and the numerical calculation of the beach profiles. The results showed that the wave direction of incident waves from the north-north-west and north-west predominated over the course of the year. Seasonal variation in the significant wave height was clear and large wave heights emerged during the winter period. On the Chirihama Beach, the multiple bar was formed, and the littoral drift in the south direction occurred.
