Abstract
After the Great Hanshin-Awaji Earthquake, Act of Improvement of Densely Building-Up Area is established. The aim is financial help for rebuild and removal of old wooden houses to prevent the fire from spreading. It is crucial for the residents to improve their resident areas under the new act. Though it is very difficult the planner and residents to make consensus as well as other urban planning. We developed supporting system for district planning to be difficult against conflagration. The characteristics is interactive and visual to realize the risk of fire-spreading and the effective alternatives of fire-preventing planning.
