Treaty of Kanagawa at Wikisource |
The Convention of Kanagawa, also known as the Kanagawa Treaty (神奈川条約, Kanagawa Jōyaku) or the Japan–US Treaty of Peace and Amity (日米和親条約, Nichibei Washin Jōyaku), was a treaty signed between the United States and the Tokugawa Shogunate on March 31, 1854. Signed under threat of force,[2] it effectively meant the end of Japan's 220-year-old policy of national seclusion (sakoku) by opening the ports of Shimoda and Hakodate to American vessels.[3] It also ensured the safety of American castaways and established the position of an American consul in Japan. The treaty precipitated the signing of similar treaties establishing diplomatic relations with other Western powers.
