Tours at OTEC Okinawa

The OTEC Okinawa facility is primarily a research facility, though it is also possible to tour when our operation and maintenance schedules permit. Over the past few years, thousands have visited to learn more about clean energy, ocean energy, deep seawater, and the OTEC facility.

Tours are generally available Monday through Friday 9am to 5pm. Please make a reservation. We may also be able to accommodate special requests for weekend or after-hours tours.

Standard Tour

Our standard tour consists of a presentation (10-30 minutes depending on focus) within the Okinawa Prefecture Research Center followed by a roughly 15 minute tour of the OTEC Facility. This option gives visitors a good background on related facilities.

This tour can also be customized to your schedule, allowing more or less time for details and questions depending on your interest.

This tour is suggested for the majority of our guests, including government officials, interested businesses, and tourists.

For those visitors in related industries we can provide more in-depth information on current OTEC development and the experiments being conducted on Kume Island. Please note that our Engineers are not always available for tours, so we request you let us know in advance if you are interested in the technical aspects of the OTEC project.
