Measures must be taken to prepare against lifeline disruptions caused by earthquakes in the Tokyo capital area. In this study, a survey was conducted targeting important hospitals in the capital area of Japan to understand the situation of water and energy supply facilities of buildings and the disaster preparedness. It is clear that disaster base hospitals tend to have highperformance energy facilities to support the continuity of operations during a disaster. This paper presents the concept of a distributed self-sustaining district to improve the local capability to overcome lifeline disruptions. The suitability of implementing this concept in the hospitals in a given district is also assessed in this study.
