     Our research field examines urban planning theories and technologies in order to develop reconstruction planning and management, and to design a social system that allows for the implementation of effective revitalization projects after disasters. We conducted our research in Japan and overseas.
1. Development and application of planning technologies at a small area level
     To make effective reconstruction plans and projects for damaged areas by disaster, it is necessary to have enough understanding of areal characteristics at a small level. To be specific, we estimated the living situations of population by each basic unit of Japanese census, which is the most detailed enumeration unit. These population datasets are then tabulated for the damaged areas by the March 11th earthquake and tsunami as well as contaminated areas by the nuclear accident in Fukushima. The results provide information on housing demands in the future and the ways of reconstruction plans for improving living conditions. Currently, we are developing an application of this methodology to expected flooded areas by tsunami caused by Tokai and Tonankai earthquake. Besides, our research projects include reconstruction planning based on Geodesign, retail reconstruction in disaster-affected areas, and analysis of human suffering by typhoon Haiyan in Philippines.
2. Practical support activities for reconstruction planning
     In the recovery process from catastrophic disasters, it is important to plan the spatial recovery plan not simply for recovery of the original condition or improvement of the disaster prevention performance, but for creation of new space and place, which solve simultaneously the preexisting industrial, environmental and social problems of the region.
Base on the awareness of these issues, we are promoting studies on the construction of physical spatial planning theory related to the recovery from catastrophic disaster, the establishment of its implementing system and the development of the management technique. To give the concrete examples, we examined the effective citizen participation process by using preexisting community council. We also clarified the planning theory of tsunami defense facilities. We are, at the same time, engaged in the practical planning support activities in the affected area in cooperation with the abovementioned research activities.
