The Ansei Treaties (Japanese: 安政条約) or the Ansei Five-Power Treaties (Japanese: 安政五カ国条約) are a series of treaties signed in 1858, during the Japanese Ansei era, between Japan on the one side, and the United States, Great Britain, Russia, Netherlands and France on the other.[1] The first treaty, also called the Harris Treaty, was signed by the United States in July 1858, with France, Russia, Britain and the Netherlands quickly followed within the year: Japan applied to the other nations the conditions granted to the United States under the "most favoured nation" provision.
Ability of foreign citizens to live and trade at will in those ports (only the opium trade was prohibited).
A system of extraterritoriality that provided for the subjugation of foreign residents to the laws of their own consular courts instead of the Japanese legal system.
Fixed low import-export duties, subject to international control, thus preventing the Japanese government from asserting control over foreign trade and protection of national industries (the rate would go as low as 5% in the 1860s.)
