To deal with large-scale disasters, it is necessary to maintain important community functions. One way to achieve this goal is through strategic collaboration with local organizations to ensure district continuity in the aftermath of disaster. It is therefore necessary for local organizations to form a consensus in order to draft measures for the reduction of disaster damage, enabling each organization to act strategically in a post-disaster situation. These measures taken together are called a district continuity plan (DCP).

In this paper, the concept of district continuity is defined as a BCP method. The utility of this method is clarified through two case studies. The Kagawa DCP focuses on a possible future Nankai Trough earthquake, and the Basin DCP against large-scale flooding is based on the DCP concept.
