Perry Opens Japan: End of 200 Years of Isolation

Commodore Matthew Perry arrived with more guns than arguments, and Japan understood the message. On March 31, 1854, the Convention of Kanagawa forced Japan to open the ports of Shimoda and Hakodate to American ships, ending more than 200 years of near-total isolation under the Tokugawa shogunate. Perry's "Black Ships," four steam-powered warships that had first appeared in Edo Bay the previous July, demonstrated a level of naval technology that Japan could not match or resist. Japan's sakoku policy, established in the 1630s, had restricted virtually all foreign contact to a tiny Dutch trading post on the artificial island of Dejima in Nagasaki harbor. The policy kept Japan stable and peaceful but left it technologically isolated. When Perry's squadron arrived belching black coal smoke from engines that Japanese observers had never seen, the technological gap between Japan and the West became impossible to ignore. Perry had been sent by President Millard Fillmore with a letter requesting trade relations, coaling stations for American ships crossing the Pacific, and humane treatment of shipwrecked American sailors. The letter was polite; the four warships were not. Perry gave the Japanese six months to consider the request, then returned in February 1854 with an even larger squadron of nine ships. The Treaty of Kanagawa was signed within weeks, granting the American demands without establishing full trade relations. The forced opening triggered a political earthquake within Japan. Samurai who blamed the shogunate for allowing foreign penetration launched the movement that toppled the Tokugawa in 1868 and restored imperial rule in the Meiji Restoration. Within 50 years, Japan had built a modern navy, industrialized its economy, defeated Russia in war, and emerged as a great power. Perry's ships did not just open Japan's ports; they detonated the old order and launched one of the most rapid national transformations in history.
