In 1961, there was torrential rain in the Inadani area of Nagano Prefecture, and they conducted a group migration project for restoration. This case was the occasion for enacting the Law on Disaster Prevention Group Relocation Promotion Project. So, this study aims to clarify the introduction process and actual conditions of a group migration project because they have not been fully clarified yet. As a result, following three points became clear. First, analyzing the Diet Proceedings, we found that group migration was selected instead of the original restoration because of the enormous disaster and limited budget. Second, although there are many candidate sites for migration, it could contribute to the formation of a compact city. Third is the enhancement of support for rebuilding livelihoods. Considering the recent situation of frequent disasters, we believe that the study will provide useful suggestions for the future promotion of group relocation projects.
