Beginning of New Epoch

The Edo era, which started in 1603 and ended in 1867, continued for 265 years. The name of city was changed from Edo to Tokyo. During the Edo era, Japan was ruled by the Tokugawa shogunate. Keio was the last period of the Edo era. This was changed to Meiji in 1868, because of the down fall of Tokugawa shogunate, and the rise of the Meiji emperor. Meiji was this first period after Edo era, and continued to Taisho, Showa and today Heisei.
The Edo era ended because of west Japan samurai's revolution against the Tokugawa shogunate. These samurais were mainly the people of present-day Kagoshima and Yamaguchi Prefecture.
The change of political system was comparatively peaceful. After the revolution, Japan began to take in much culture from the world.
