Osaka is the third largest city in Japan, with a population of over 17 million people in its greater metropolitan area. It is the central metropolis of the Kansai region and the largest of the Osaka-Kobe-Kyoto trio.If Tokyo is Japan's capital, one might call Osaka its anti-capital. Whatever you call it, though, there are many opportunities for you to discover its true anti-character.
Osaka dates back to the Asuka and Nara period. Under the name Naniwa, it was the capital of Japan from 683 to 745, long before the upstarts at Kyoto took over. Even after the capital was moved elsewhere, Osaka continued to play an important role as a hub for land, sea and river-canal transportation.
During the Tokugawa era, while Edo (now Tokyo) served as the austere seat of military power and Kyoto was the home of the Imperial court and its effete courtiers, Osaka served as "the Nation's Kitchen" (tenka-no-daidokoro), the collection and distribution point for rice, the most important measure of wealth.
