Expo '75 (Japanese: 沖縄国際海洋博覧会, Okinawa kokusai kaiyou hakurankai) was a World's Fair held on the island of Okinawa in Japan from July 20, 1975 to January 18, 1976.
Expo 75 was conceived, in part, to commemorate the American handover of Okinawa to Japan in 1972. The theme of the exposition was the oceans, and focused on oceanographic technologies, marine life, and oceanic cultures. The motto was “The sea we would like to see" (Japanese: 海－その望ましい未来, Umi - sono nozoma shii mirai).
The event was located on the western end of the Motobu Peninsula, with a site area of 1,000,000 square meters (including sea areas). Thirty-seven nations participated, along with eight domestic and three international organizations. The keynote speaker on opening day was American author James A. Michener.
