In Niigata Prefecture, there have been efforts to promote the implementation of marine energy as part of the "Niigata Green New Deal Policy." Since the waters offshore of Awashima Island in Niigata Prefecture were designated as a marine renewable energy testing field, the Niigata Prefecture Marine Energy Research Association and Nihon University's College of Science and Technology have been working together on experiments on floating small-scale marine current power devices. As active use of the testing field is also expected to stimulate other activities in the region, we intend to put forth all efforts in future to ensure successful utilization of this testing field.
