Abstract
The management of coastal amenity resources was investigated along Hakata Bay having diverse coastline in the city area. It was shown that dominating factors of the coastal amenities were landscape, accessibility, naturalness, intimacy of water and amusement, and that the weight of these factors was different among the styles of coast natural, urban living and urban leisure coast. Further, we evaluated the monetized value of the coast: by use of willingness-to-pay method and the restoration cost method proposed for the sake of natural coast. Then, we discussed the effect of water quality implovement on the value of coastal amenities and what the mitigation of coast in the city area should be.
