The first westerner to have a positive relationship with Japan and open up dialogue about trade with the US was Commodore Matthew C. Perry. In 1853, Perry led a naval expedition to Japan and successfully negotiated the Treaty of Kanagawa, which opened up two Japanese ports to American trade and established diplomatic relations between the two countries. This was a significant event in the history of Japan, as it marked the beginning of the end of its isolationist policy and the start of its modernization.
