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. Visitors can learn about current and future OTEC projects, the properties and use of deep seawater, OTEC economics, OTEC basics, and far more.

In order to match the varied interests our visitors have, we can provide a flexible variety of tours. 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.
