Worldwide coastal cities face growing threats from environmental factors such as land subsidence. This study compares the policies implemented by the Tokyo and Semarang Governments to address the issue of land subsidence. The study aims to analyze the condition of land subsidence in the two cities and to identify successful adaptation patterns that can serve as a reference for other coastal cities facing similar issues. The method used in this study is a literature review of references that discuss land subsidence and related policies. The findings indicate that the Tokyo government has successfully tackled the problem of excessive groundwater pumping which is the leading cause of land subsidence and reconstructed the coastal areas that were prone to flooding due to subsidence.The Semarang government has implemented Regional Government plans to address the issue, but floods still inundate many coastal areas and many communities are still affected. Therefore, there is a need to strengthen embankments and coastal construction to prevent flooding along the entire Semarang coast. A more comprehensive approach and long-term planning are necessary to manage land subsidence risks effectively. The study's findings provide insights that can help other coastal cities to address the issue and mitigate its impacts.
