Coastal areas are a critical space for humans and other living things and must be properly managed. Coastal management is complicated by the diverse use of coastal areas by diverse individuals. The proposed method is integrated coastal area management that integrates various sectors. Satoumi has been proposed and practiced in Japan and is one of the voluntary coastal zone managements of shallow water. The author proposed a multilevel management system with Satoumi as a basic element. The multilevel management system manages the waters under the jurisdiction of prefectures through multistep efforts such as providing Satoumi, Satoumi networks, and administrative coastal infrastructure. The author also proposed that multistep efforts be bundled with network governance. In this report, after introducing the multistep management system, the efforts of coastal zone management in Shizugawa Bay and the coast of Kagawa Prefecture in Japan were evaluated as a multistep management system and network governance, and the characteristics and issues of each approach were extracted. Furthermore, the effectiveness of multilevel management systems and network governance were examined.
