9th Ocean Energy and Economic Development Symposium

Since 2010, when the Japanese Ministry of Economy Trade and Industry, the United States Department of Energy, Okinawa Prefecture, and the State of Hawai’i signed a Memorandum of Cooperation to develop and deploy clean and renewable energies as the “Hawai'i Okinawa Partnership on Clean and Efficient Energy Development and Deployment,” there have been multiple activities focusing on the possibility of cooperative projects relating to the introduction of clean energy. As one of the activities, ocean energy workshops were held annually and included themes such as economic development, education, and resiliency. In 2020, Okinawa Prefecture will expand the theme to Clean Energy in general and hold a workshop in Okinawa (web format).



The 2018 Symposium was cancelled by Organizer Okinawa Prefecture due to Typhoon 1824. Thank you for your understanding and cooperation.


The 2018 Full Agenda is now available. Please download it here (PDF).
