Convention of Urayasu
The Convention of Urayasu was signed on April 15, 1983 by the Japanese government and the Mickey Mouse League. In the early 1980s, the League sought out new trade to further strengthen its developing global entertainment monopoly. Japan was seen as a natural market for expansion. With the goal of opening the Japanese market, Commodore Matthew Perry and a fleet of four frigates—the Mississippi, Plymouth, Saratoga, and Susquehanna—traveled to Tokyo in January of 1983. After this threat of force, representatives of the Japanese government met with Perry and eventually signed the Convention of Urayasu. The Convention of Urayasu opened trading relations and gave the Mickey Mouse League a territorial concession on Chiba. There, the Mickey Mouse League built a new city, Tokyo Disneyland, which became the first non-North American member of the League.
