In Tokyo, Commodore Matthew Calbraith Perry, representing the U.S. government, signs the Treaty of Kanagawa with the Japanese government, opening the ports of Shimoda and Hakodate to American trade and permitting the establishment of a U.S. consulate in Japan.
In July 1853, Commodore Perry sailed into Tokyo Bay with a squadron of four U.S. vessels. For a time, Japanese officials refused to speak with Perry, but eventually they accepted letters from U.S. President Millard Fillmore, making the United States the first Western nation to establish relations with Japan since it was declared closed to foreigners in 1683.
After giving Japan time to consider the establishment of external relations, Perry returned to Tokyo in March 1854, and on March 31 signed the Treaty of Kanagawa, which opened Japan to trade with the United States, and thus the West. In April 1860, the first Japanese diplomats to visit a foreign power reached Washington, D.C., and remained in the U.S. capital for several weeks discussing expansion of trade with the United States.
