Preserving dry stone walls on agricultural land is one of the important factors in achieving sustainable development. The EU has provided substantial financial support based on that philosophy. Therefore, we summarize the features and issues of the EU's subsidy system for the restoration of dry stone walls and the way it is used in practice, using the Liguria Vernazza in Italy as a case study. After that, we organized the characteristics of three subsidy systems for the restoration of dry stone walls in Japan and examined the way of public subsidy for dry stone walls in Japan from the five points, referring to the EU system. As a result, we discussed the following issues. Firstly, The problems that can be caused by the framework of the system. Secondly, the problem that the requirement of receiving the subsidy is after dry stone walls are collapsed. Thirdly, the reasons and standards that should be limited to dry stone walls, the securing of materials. Fourth, the reasons why the builder should be a farmer and the way of technique succession. Fifth, the simplification of the procedure and the support of the procedure.
