Department of International Affairs and Research. Chief Director for Research Planning .
Specialty is environmental science and soil science. Especially, I am studying about a chemical behavior of mercury in soil or aquatic system.

Research on its influences and behaviors of mercury in an aquatic environment of Minamata Bay.
