What is the Meiji Restoration in the nonfiction book, Karate-Do: My Way of Life?

Meiji Restoration is the name of a political movement that begins in 1870 in Edo, which is the name of a city in Japan now called Tokyo. The Meiji Restoration is opposed by many traditional Japanese citizens who object to their cultural rules. For example, the Meiji administration requires applicants who sit for the medical school entrance exams to have been born in 1870 or later regardless of their actual age. In addition the Meiji government bans the practice of karate.
