Question

Quizplus · Accepted Answer

Japan opened its shores to Western trade as a response to U.S. military pressure. In 1853, U.S. Commodore Matthew Perry arrived in Japan with a fleet of four warships and demanded that Japan open its ports to trade with the United States. Japan realized that it had fallen behind the Western world and needed to modernize and expand its economy to avoid colonization or domination by Western powers. As a result, Japan signed the Treaty of Kanagawa with the United States in 1854, which opened two Japanese ports to American ships and started a period of modernization and economic expansion known as the Meiji Restoration.
