From both a historical and geographical standpoint, Nagasaki has prospered as the center of "ocean" related innovation. The Nagasaki Marine Industry Cluster was formed in March 2014 by local industry leaders, with an eye on actively and centrally integrating the prefecture's industries into new marine industry fields, especially with marine renewable energy as the pillar. In the three years since its establishment, the Cluster has begun joint research into the development and improvement of a hydraulic tidal current turbine system for power generation and has also taken up efforts to work together with companies in the local community.
