The Edo period(江戸時代,Edo jidai?), or Tokugawa period(徳川時代,Tokugawa jidai?) is the period between 1603 and 1868 in the history of Japan, when Japanese society was under the rule of the Tokugawa shogunate and the country's 300 regional Daimyo. The period was characterized by economic growth, strict social order, isolationist foreign policies and an increase in both environmental protection and popular enjoyment of arts and culture. The shogunate was officially established in Edo on March 24, 1603 by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration on May 3, 1868 after the fall of Edo.
