How did america's influence transform tokugawa japan and meiji japan?

When the United States sends a naval delegation, led by Commodore Matthew Perry, to "open" Japanese ports in 1853, the Japanese are well aware of the "Unequal Treaties" that have been imposed upon China in the previous ten years (since the Opium War of 1839-42) as a result of the superior military power of the Western nations. The Japanese respond to the challenge of the West.Reform-minded samurai, reflecting the enormous changes that have taken place in the preceding Tokugawa period, effect political change. They launch the reform movement under the guise of restoring the emperor to power, thereby eliminating the power of the shogun, or military ruler, of the Tokugawa period. The emperor's reign name is Meiji; hence the title, "Meiji Restoration" of 1868.
