Which historical figure is associated with improving relations between the U.S. and Japan?

Commodore Matthew Perry is recognized for his pivotal role in improving relations between the United States and Japan during the mid-19th century. In 1853, Perry led a naval expedition to Japan, where he aimed to open the country to American trade. At this time, Japan was largely isolated from the rest of the world under the Sakoku policy, which restricted foreign influence and trade.

Perry's approach combined show of military strength with diplomatic engagement, leading to the signing of the Treaty of Kanagawa in 1854. This treaty marked a significant turning point in Japan's foreign relations, as it opened up two Japanese ports to American ships and established a basis for future trade and diplomatic agreements.

This initiative not only fostered better relations between the U.S. and Japan but also contributed to Japan's eventual modernization and engagement with the global community. Perry's mission is often credited with ushering in the end of Japan's isolationist policies and is a key moment in both countries' histories.
