The cause of beach erosion in Japan is classified into seven types. Of these, examples associated with the formation of wave-shelter zones and decreased fluvial sediment supply were studied, typified by changes in beaches at the Shimobara fishing port and along the Enshu-nada coast caused by decreased fluvial sediment supply from the Tenryu River. Such erosion is closely related to land management and the "sector-by-sector" system in Japan. The prevention of beach erosion thus requires both scientific research and improvement in coastal management through enhancing the public consensus.
