The Treaty of Amity and Commerce between Japan and the United States (日米修好通商条約, Nichibei Shūkō Tsūshō Jōyaku), also called the Harris Treaty, opened the ports of Kanagawa and four other Japanese cities to trade and granted extraterritoriality to foreigners, among a number of trading stipulations. It was signed on the deck of the USS Powhatan in Edo (now Tokyo) Bay on July 29, 1858.
