Abstract
The numbers of the municipalities developing artificial streams (seseragi) with reclaimed wastewater are increasing in Japan. For example, “Yawata-no Mori Hotaru-no Sato” was developed to enhance the environment where firefly can survive and to encourage environmental activities at Tadotsu Town, Kagawa Prefecture. The questionnaire survey was carried out to evaluate multiple benefits of seseragi with reclaimed wastewater using conjoint analysis. As a result, benefits of the preservation of aquatic ecosystems, the securing of a safe contact to water, the maintaining of landscape, and the encouraging of environmental activities were estimated at 4, 419 yen, 1, 375 yen, 4, 094 yen and 918yen per household annually. And total benefit of “Yawata-no Mori Hotaru-no Sato” was estimated about 150 milion yen annually.
