Abstract
This paper presents the fast attempt to estimate the environmental value of restoring the eco-system of the Isahaya Bay Wetland by using the Contingent Valuation Method (CVM), in the three cities of Kyushu- Isahaya, Nagasaki and Kitakyushu. Mail survey technique and double bounded dichotomous-choice (DC) format have been used for eliciting willingness-to-pay (WTP). From the results of the study we have found that, the Isahaya Bay Wetland is worth approximately 218 million yen, 1.1 billion yen and 2.7 billion yen to the residents of Isahaya, Nagasaki and Kitakyushu, respectively. The study also revealed that, average willingness to pay of the respondents rises as the distance from the project site increases and gradually settles around a certain average amount.
