Tokyo has a 400-year history as the capital of Japan that started at the beginning of the Edo period. During this time, it suffered from earthquakes and war, but in the postwar period it was the driving force behind Japan's miraculous economic growth. Today, about 13 million people, nearly 10 percent of the nation's population, live, work, rest and learn in Tokyo. Tokyo has advanced in all fields, such as politics, economy and culture, and is the center of Japan's economy and society.
