Contact with the West
The first contact with the West occurred about 1542, when a Portuguese ship, blown off its course to China, landed in Japan. Firearms introduced by Portuguese would bring the major innovation to Sengoku period culminating in the Battle of Nagashino where reportedly 3,000 rifles (actual number is believed to be around 2,000) cut down charging ranks of Samurai. During the next century, traders from Portugal, the Netherlands, England, and Spain arrived, as did Jesuit, Dominican, and Franciscan missionaries.
During the early part of the 17th century, Japan's Tokugawa Shogunate suspected that the traders and missionaries were actually forerunners of a military conquest by European powers. This caused the shogunate to place foreigners under progressively tighter restrictions. An English mariner named William Adams had journeyed with a Dutch fleet and been shipwrecked in Japan in 1600. He had managed to impress Shogun Tokugawa Ieyasu with his seafaring knowledge and was made an honorary Samurai and granted a large estate. When English traders from the East India Company made landfall in 1613 they were able to obtain Adams' assistance, as a favourite of the Shogun, in establishing a factory - a house or place for mercantile factors or agents. Ultimately, Japan forced all foreigners to leave and barred all relations with the outside world except for severely restricted commercial contacts with Dutch and Chinese merchants at Nagasaki.
Russian encroachments from the north led the shogunate to extend direct rule to Hokkaido and Sakhalin in 1807 but the policy of exclusion continued. This isolation lasted for 200 years, until, 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 (Tokyo) and displayed the threatening power of his ships' cannon. He demanded 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 (March 31, 1854), Perry returned with seven ships and forced the Shogun to 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.
Within several years, renewed contact with the West profoundly altered Japanese society. After the brief Boshin War of 1868, the shogun was forced to resign, and the emperor was restored to power. The subsequent "Meiji Restoration" initiated many reforms. The feudal system was abolished, and numerous Western institutions were adopted, including a Western legal system and constitutional government along quasi-parliamentary lines.
Russian pressure from the north appeared again after Muraviev had gained Outer Manchuria at Aigun (1858) and Peking (1860). This led to heavy Russian pressure on Sakhalin which the Japanese eventually yielded in exchange for the Kuril islands (1875). The Ryukyu Islands were similarly secured in 1879, establishing the borders within which Japan would "enter the World". In 1898, the last of the "unequal treaties" with Western powers was removed, signalling Japan's new status among the nations of the world. In a few decades, by creating modern social, educational, economic, military, and industrial systems, the Emperor Meiji's "controlled revolution" had transformed a feudal and isolated state into a world power.
