The ecological breakwater constructed at Mishima-Kawanoe Port in Ehime Prefecture in 2005. This study presents results of questionnaire surveys using Contingent Valuation Method (CVM) and Fuzzy Structural Modeling (FSM) method relevant to Willingness to pay (WTP) of Eco-breakwater. The structure of the various effects of Eco-breakwater is established by FSM method, which is an equation of calculating the total WTP of various effects by eliminating double counts. The B/C ratio is calculated as more than 7.0 by using CVM and FSM method, showing social significance on installation of Eco-breakwater.
