Commodore Perry and the Opening of Japan (1853–1854)

The "Black Ships" That Ended Sakoku

In July 1853, Commodore Matthew C. Perry led a U.S. Navy squadron of four warships (two steam frigates: Mississippi, Susquehanna; two sloops: Plymouth, Saratoga) into Edo (Tokyo) Bay.

The Demand

Perry delivered a letter from President Fillmore demanding:

• Opening of Japanese ports to American ships for supplies (coal, water, food)
• Protection for shipwrecked sailors
• Right to trade

Japanese Response

• Shogunate (Tokugawa) recognized overwhelming firepower (Paixhans guns, steam propulsion)
• Could not resist militarily; chose negotiation
• Treaty of Kanagawa (March 31, 1854): Opened Shimoda & Hakodate to U.S. ships; established U.S. consul
• Harris Treaty (1858): Full commercial relations, extraterritoriality, low fixed tariffs

Impact

• Ended Sakoku (200+ years of isolation)
• Catalyzed Meiji Restoration (1868) – modernization, industrialization, imperial expansion
• Unequal treaties → nationalist backlash → militarism → WWII

Perry's "gunboat diplomacy" shattered Japan's seclusion, redirecting its history.
