Treaty of Amity and Commerce (United States–Japan)



The Treaty of Amity and Commerce (日米修好通商条約), also called the Harris Treaty, between the United States and Japan was signed on the deck of the USS Powhatan (1850) in Edo (now Tokyo) Bay on July 29, 1858. It opened the ports of Kanagawa and four other Japanese cities to trade and granted extraterritoriality to foreigners, among a number of trading stipulations.

The Treaty


The treaty followed the 1854 Convention of Kanagawa, which granted coaling rights for US ships and allowed for a US Consul in Shimoda. Although Commodore Matthew Perry secured fuel for US ships and protection for US sailors, he left the important matter of trading rights to Townsend Harris, another US envoy who negotiated with the Tokugawa shogunate; the treaty is therefore often referred to as the "Harris Treaty". It took two years to break down Japanese resistance, but with the threat of looming British demands for similar privileges, the Tokugawa government eventually capitulated.

Among the most important points were:


 * exchange of diplomatic agent
 * in addition to the existing ports of Shimoda and Hakodate, the ports of Kanagawa and Nagasaki to be open to foreign trade effective 4 July 1859 and thereafter Niigata, and Hyōgo opened on 1 January 1860 and 1 January 1863 respectively
 * in all the treaty ports listed, United States citizens may permanently reside, have the right to lease ground and purchase the buildings thereon, and may erect dwellings and warehouses
 * a system of extraterritoriality that provided for the subjugation of foreign residents to the laws of their own consular courts instead of the Japanese law system
 * fixed low import-export duties, subject to international control
 * right of freedom of religious expression and church construction to serve the needs of United States nationals within the confines of the designated foreign settlements at the treaty ports

The agreement served as a model for similar treaties signed by Japan with other foreign countries in the ensuing weeks. These Unequal Treaties curtailed Japanese sovereignty for the first time in its history; more importantly, it revealed Japan’s growing weakness, and was seen by the West as a pretext for possible colonisation of Japan. The recovery of national status and strength became an overarching priority for the Japanese, with the treaty's domestic consequences being the end of Bakufu (Shogun) control and the establishment of a new imperial government.

American interests in Japan
Perry's expedition to Japan is theoretically linked to the notion of manifest destiny, in which Americans had a "God-given" right to spread their political institutions and commerce across North America. The role of Japan in particular was that of a base of commerce between China and the United States. According to US Secretary of State Daniel Webster, God had placed coal for steam ships and other trading vessels "in the depths of the Japanese islands for the benefit of the human family." The idea of "Manifest Destiny" as an imperialistic measure outside of North America was not introduced as a significant idea until the Republican bid for office in 1892, thereby suggesting, in practicality, a mere economic interest in Japan, as it held coal reserves in key locations for Pacific trade.

Extension of the "Perry Crisis"
The Convention of Kanagawa mediated by Commodore Perry was a primary step to a rather forced extension of American influence in Japan. However, most problems that the Tokugawa Shogunate faced came from a division within the country between those who favored opening to the West immediately (kaikoku) and advocates of joi ("expel the barbarian") who favored a preservation of Japanese culture and influence until Japan could face the military threat posed by the West. Most Japanese were familiar with the subjugation of Chinese trade by the British after the Opium War of 1840, but they were divided on how and when they would inevitably open their ports. Both camps did agree that trade should be handled by Japanese going overseas instead of foreigners coming into Japan and violating the country's seclusion laws. Many of those Tokugawan officials who agreed to the Treaty of Kanagawa did so in an effort to avoid war with the United States or Britain. The result was a deepening domestic crisis; after 1858, the Shogunate was trapped between the demands of the West and its powerful domestic enemies.

However, Townsend Harris' terms were much more demanding than Perry's. Harris claimed that the laws of Japan were "very peculiar" and it would be unfair for foreigners to live under such rule. Article III of the treaty gave Americans the right to trade and reside in Yedo (Tokyo) and Osaka without influence from the Japanese government; the treaty also allowed for consular jurisdiction in those cities opened to American trade, the free export of Japanese gold and silver, and a conventional tariff. The entrance of foreigners to the port of Edo, the shogunal capital, and the placement of an official from a foreign government in proximity to the Emperor was threatening, even to those who supported opening to the West publicly. These demands in particular demonstrated the United States' planned role for Japan; there was to be freedom of trade, allowance for an influx of Americans, (but no expectations of Japanese coming to the United States), no interest in military concerns, and religious toleration of Japanese tradition. It was merely a link in a chain of commerce that would connect North America to China.

Harris' emphasis (and threat) of the inevitable defeat of the resisting Japanese by the British and the French was enough to convince many of the kaikoku members of the Tokugawa Shogunate to agree to the terms of the United States, no matter how unfavorable they were. The memory of China's overwhelming defeat was too close to be ignored.

Additional Treaties
After reluctantly accepting the Harris Treaty, Japan quickly signed similar treaties, called the Ansei Treaties, with Russia, France, Great Britain, and the Netherlands. This process was hastened by the outcome of the Arrow War in 1858 in which the Chinese were once again soundly defeated by the British and the French. Harris also suggested that Japan sign "honorable treaties" before the allied Anglo-French fleet would sail to Japan and coerce the signing of "unequal treaties". However, the content of those treaties did not differ in their most essential points from the Tientsin Treaty between Great Britain and China in 1858; one of the most prominent of the unequal treaties in the history of Eastern-Western foreign relations.

Ratification


The Treaty was ratified through the visit of the first Japanese Embassy to the United States in 1860. The new relationship with the United States has been cited as a factor in the assassination of Ii Naosuke.

Effects
According to a 2017 study, the treaties reducing trade barriers between Japan and Western powers caused GDP to increase in Japan by 7 percent in the immediate period.
