History of Japan Timeline

American Commodore Matthew Perry sailed his 'Black Ships' into Edo Bay, demanding that Japan open its ports to trade with the United States. His display of modern naval technology exposed the weakness of Tokugawa isolationism and forced Japan to end more than two centuries of seclusion.

Under pressure from Perry's fleet, the shogunate signed the Treaty of Kanagawa, opening the ports of Shimoda and Hakodate to American ships. Similar 'unequal treaties' with other Western powers soon followed, undermining Tokugawa authority and fueling calls for national renewal.
