Abstract
In 2005, the Cabinet Office reported the damage assessment of the Tokyo metropolitan earthquake, and over one million households who lose their houses were estimated. In Japan, the prefabricated temporary house is the main countermeasure of temporary housing assistance. Recently, the Natural Disaster Victims Relief Law was reformed, and a system of rent subsidies was established. In the event of large urban disaster, it is not clear whether the present system will work effectively. In order to design institutional arrangements as well as to make preliminary considerations, policy simulation is a useful research approach. To construct reliable policy simulation, we developed household's discrete choice model of temporary housing using the sample data from internet-base questionnaire system. According to the constructed model, the choice probabilities came to be able to calculate in all conditions such as household's attributes and housing conditions.
