Research Abstract	The aim of this study is to investigate feasibility of flood mitigation strategies using river basin management and effective and sustainable countermeasures for flood disasters as well as its implementation plan. The investigations showed that the social benefits of landuse and building regulations exceeded the costs in both Tokyo and Osaka regions, which are the highest population density areas in Japan, indicating that the above regulation strategies have a degree of applicability as a countermeasure for flood disasters. The result of the cost-benefit analysis also shows that the impact of the regulation strategies on a low income group would be greater than higher income groups.
