To this day in Japan, the water supply service for agricultural use has been formed as the supply-driven system. In fact, the farmers can use the utilization volume of agricultural water, and they have to pay the price of agricultural water fee decided by water supplier side. The purpose of this study is to clarify the present condition and consciousness of rice farmers about water use by interview survey in case of Aichi-Yosui irrigation area and to analyze the agricultural water management system from an economic viewpoint. Second, we propose the evaluation concept and simulation method for construct of the desirable water service system as a regional policy. In this study, the model analysis suggests that demand-driven irrigation facilities can fit appropriately with the needs of each farmer and simultaneously increase the productivity of the entire region.
