    (1) Designation of the Nagasaki test areas
    In July 2014, three marine areas in the Nagasaki Prefecture were designated by the Japanese Government as officially endorsed test sites. These areas provide excellent potential for the operation of tidal current and offshore wind power turbines because of the presence of favourable natural resource conditions including attractive tidal current speeds and wind speeds. The Prefectural Government has already secured the consent of local fishermen to the use of these marine areas as test fields through a series of negotiations.
    (2) About the Nagasaki Marine Industry Cluster Promotion Association
    To make Nagasaki a center for the marine renewable energy industry, an NPO organization, Nagasaki Marine Industry Cluster Promotion Association (NAMICPA) was established with the following aims:
    · Provide support to encourage and enable companies in Nagasaki Prefecture to enter the marine renewable energy field and to help local companies develop this business sector, while gaining experience in this sector.
    · Help facilitate research and development at companies that belong to this industrial cluster.
    · To help facilitate member companies to receive more orders and create commercial opportunities for the members working in cooperation with device makers and other project partners.
