TheAnsei Treaties (Japanese: 安政条約) or theAnsei Five-Power Treaties (Japanese: 安政五カ国条約) are a series of treaties signed in 1858, during the JapaneseAnsei 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 theHarris 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.

The most important points of theseunequal treaties are:

• Exchange of diplomatic agents.
• Edo,Kobe,Nagasaki,Niigata, andYokohama’s opening to foreign trade as ports.
• Ability of foreign citizens to live and trade at will in those ports (only theopium trade was prohibited).
• A system ofextraterritoriality that provided for the subjugation of foreign residents to the laws of their ownconsular courts instead of the Japanese legal system.
• Fixed low import-export duties, subject to international control, thus preventing theJapanese government from asserting control over foreign trade and protection of national industries (the rate would go as low as 5% in the 1860s.)

The five treaties known collectively as the Ansei Treaties were:

• TheTreaty of Amity and Commerce between the United States and Japan(Harris Treaty) on July 29, 1858.
• TheTreaty of Amity and Commerce between the Netherlands and Japan on August 18, 1858.
• TheTreaty of Amity and Commerce between Russia and Japan [ja] on August 19, 1858.
• TheAnglo-Japanese Treaty of Amity and Commerce on August 26, 1858.
• TheTreaty of Amity and Commerce between France and Japan on October 9, 1858.

The 1976 Broadway musicalPacific Overtures, which focuses on Japan during and after the Perry Expedition, includes a song titled "Please Hello" which satirically depicts the coercive process by which imperial powers forced Japan to agree to the Ansei Treaties.
