Abstract
Japanese coasts have experienced extensive damage caused by storm surges and high waves which made new high records. The impacts of climate change and sea-level rise are suggested to increase in this century. To address these impacts, as protection by hard structures such as coastal dike and seawall has limited effects, integrated policy for coastal conservation should be introduced, combining hard and soft options. Soft options include land use change/regulation, early warning system and disaster prevention scheme. Trends of national population and financial conditions are another factors for the future policy. This paper examines coastal conservation and management policy against sea-level rise caused by global warming through review of existing policy framework in foreign countries as well as in Japan, options of integrated policy, questionnaire survey of coastal residents' opinion, and quantitative assessment of those options. Through these studies, future direction of coastal management is proposed taking into account the effects of climate change and sea-level rise.
