Global fresh water resources are increasingly being polluted and depleted, threatening sustainable development and human and ecosystem health. Learning from the case-studies of different watershed managements in U.S.A., Switzerland and Japan is useful to provide educational materialds for udergraduate and graduate program on water environment and water resoruce management. In this study, comparative study on water management policy and projects among Japan, U.S.A, and EU was carried out to exlpore useful information to develop sustainable watershed management. The comparison helped to find future tasks in improvement in watershed management in Japan.
