Edo Period (1603 - 1868)
 
             During the Edo Period (江戸時代), the administration of the country was shared by over two hundred daimyo. The Tokugawa clan, leader of the victorious eastern army in the Battle of Sekigahara, was the most powerful of them, and for fifteen generations monopolized the title of Sei-i Taishōgun (often shortened to shōgun). With their headquarters at Edo (present-day Tokyo), the Tokugawa commanded the allegiance of the other daimyo, who in turn ruled their domains with a rather high degree of autonomy.
The shogunate carried out a number of significant policies. They placed the samurai class above the commoners: the agriculturists, artisans, and merchants. They enacted sumptuary laws limiting hair style, dress, and accessories. They organized commoners into groups of five, and held all responsible for the acts of each individual. To prevent daimyo from rebelling, the shoguns required them to maintain lavish residences in Edo and live at these residences on a rotating schedule; carry out expensive processions to and from their domains; contribute to the upkeep of shrines, temples, and roads; and seek permission before repairing their castles.
           Many artistic developments took place during the Edo Period. Most significant among them were the ukiyo-e form of wood-block print, and the kabuki and bunraku theaters. Also, many of the most famous works for the koto and shakuhachi date from this time period.
            Throughout the Edo Period, the development of commerce, the rise of the cities, and the pressure from foreign countries changed the environment in which the shoguns and daimyo ruled. In 1868, following the Boshin War, the shogunate collapsed, and a new government coalesced around the Emperor.
Seclusion
            Japan"s first treatise on Western anatomy, published in 1774, an example of Rangaku.During the early part of the 17th century, the shogunate suspected that the traders and missionaries were actually forerunners of a military conquest by European powers. Christianity spread in Japan, especially among peasants. The shogunate suspected the loyalty of Christian peasants towards their daimyos and severely persecuted them. This led to a revolt by persecuted peasants and Christians in 1637 known as the Shimabara Rebellion which saw 30,000 Christians, samurai, and peasants facing a massive samurai army of more than 100,000 sent from Edo. The rebellion was crushed at a high cost to the shogun"s army. After the eradication of the rebels at Shimabara, the shogunate placed foreigners under progressively tighter restrictions. It monopolized foreign policy, and expelled traders, missionaries, and foreigners, with the exception of the Dutch and the Chinese merchants restricted to the man-made island of Dejima in Nagasaki Bay and several small trading outposts outside the country. However, during this period of isolation (Sakoku) that began in 1635, Japan was much less cut off from the rest of the world than is commonly assumed, and some acquisition of western knowledge occurred under the Rangaku system.
            Russian encroachments from the north led the shogunate to extend direct rule to Hokkaidō, Sakhalin and the Kuriles in 1807, but the policy of exclusion continued.
End of seclusion
           The policy of isolation lasted for more than 200 years. In 1844, William II of the Netherlands sent a message urging Japan to open her doors, which resulted in Tokugawa shogunate"s rejection.[24] On July 8, 1853, Commodore Matthew Perry of the U.S. Navy with four warships — the Mississippi, Plymouth, Saratoga, and Susquehanna — steamed into the bay at Edo, old Tokyo, and displayed the threatening power of his ships" cannons during a Christian burial, which the Japanese observed. He requested that Japan open to trade with the West. These ships became known as the kurofune, the Black Ships.
            The following year, at the Convention of Kanagawa on March 31, 1854, Perry returned with seven ships and requested that the Shogun sign the "Treaty of Peace and Amity," establishing formal diplomatic relations between Japan and the United States. Within five years Japan had signed similar treaties with other western countries. The Harris Treaty was signed with the United States on July 29, 1858. These treaties were widely regarded by Japanese intellectuals as unequal, having been forced on Japan through gunboat diplomacy, and as a sign of the West"s desire to incorporate Japan into the imperialism that had been taking hold of the rest of the Asian continent. Among other measures, they gave the Western nations unequivocal control of tariffs on imports and the right of extraterritoriality to all their visiting nationals. They would remain a sticking point in Japan"s relations with the West up to the turn of the century.
