Documents obtained by The Okinawa Times show that the United States government had detailed plans for constructing a nuclear power plant in Okinawa Prefecture in the 1960s when it was under U.S rule.

According to the plans, the site for the nuclear power plant with two reactors would have been where Okinawa Electric Power Co.'s Kin thermal power plant is now located. The plans call for the first reactor to be completed in December 1963, and the second one in 1965.

The finding comes 10 years after the Great East Japan Earthquake and subsequent tsunami and triple meltdown at the Fukushima No. 1 nuclear plant.
