Sea level rise due to global warming will cause different impacts for each region. For a example, some prefectures in Japan may suffer from disappearance of sandy shore when the rise level is over 65cm. As precedent researches, we have conducted to derive recreation demand function by travel cost method, to construct an applied general equilibrium model with the specified utility function which is consistent with the demand function above, and then to evaluate the damage of sand erosion in monetary terms. This study also modifies the model to estimate the damages by region and scenario of sea level rise. In addition, a prototype virtual adaptation policy is designed with some past instances of artificial beach nourishment project, and is examined in context of cost-benefit analysis. As a result, when the sea level rise are 30cm and 65cm, the minimum damage are estimated as 0.08 and 0.16 billion yen per year for Tokushima Pref. and the maximum ones are 6.0 and 7.25 billion yen per year for Okinawa Pref.. On the viewpoint of effectiveness about the designed virtual adaptation policy, the cost-benefit ratio exceeds 1 for 17 Pref. (30cm) and 20 Pref. (65cm) among 39 regions those have sand shore in their area.
