SThe Ministry of Land, Infrastructure, Transport and Tourism is working on developing new method to utilize geosynthetics for coastal protection. Concrete blocks have been used for constructing coastal facilities which aimed to protect the country from tsunamis, storm surges, waves and coastal erosion on the Japanese coast. Recently, geosynthetics is expected to be used for coastal protection, because the removability becomes to be required for coastal structures through beach nourishment. Moreover, demands for reduction of construction cost and improvement on ocean view were gradually increased. In this study, as an example of coastal structure which made of geosynthetics, "Sand filled bag - Cell type gravel mat" was proposed. In order to verify the actual workability on the coast, the trial construction in the company yards, the real test construction on the coast, and the observations were carried out periodically after the real test construction.
