With a population of 2.5 million, Osaka is Japan's third largest and second most important city. It has been the economic powerhouse of the Kansai region for many centuries. Osaka was formerly known as Naniwa. Before the Nara Period, when the capital used to be moved with the reign of each new emperor, Naniwa was once Japan's capital city, the first one ever known.
In the 16th century, Toyotomi Hideyoshi chose Osaka as the location for his castle, and the city may have become Japan's capital if Tokugawa Ieyasu had not terminated the Toyotomi lineage after Hideyoshi's death and moved his government to distant Edo (Tokyo).
If Tokyo is Japan's capital, one might call Osaka its anti-capital. With what you will call it so, however, is left much open to your own findings upon the visit to the city. Veiled much with a commercial-centric city touch, you may as well start from picking up the lively intonation of Osaka dialect, heard from the people as you ride on the escalators standing on the right, instead of the left in Tokyo; then discovering the contrast of popular food to eastern Japan, as you look for places to lunch. The deeper you get inside, and at the end of your stay, it is not completely impossible that you may have compiled your own original list of reasons covering from history, culture, sports, to business.
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. (See "808 Bridges" infobox.) 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" the collection and distribution point for rice, the most important measure of wealth. Hence it was also the city where merchants made and lost fortunes and received repeated cheerfully ignored warnings from the shogunate to reduce their conspicuous consumption.
During Meiji era, Osaka's fearless entrepreneurs took the lead in industrial development, making it the equivalent of Manchester in the U.K. A thorough drubbing in World War 2 left little evidence of this glorious past — even the castle is a ferroconcrete reconstruction — but to this day, while unappealing and gruff on the surface, Osaka remains Japan's best place to eat, drink and party, and in legend (if not in practice) Osakans still greet each other with mokarimakka?, "are you making money?".
The main international gateway to Osaka is Kansai International Airport (ICAO: KIX), covered in a separate article. Domestic flights, however, some arrive at Osaka International Airport, more commonly called Itami Airport (ICAO: ITM), which despite the name hasn't had a single international flight since 1994. Itami is connected to the Osaka Monorail, but the monorail is expensive and traces an arc around the northern suburbs, so to get to the centre of the city you will need to transfer to a suburban Hankyu railway line. A more convenient option for most are the Airport Limousine Buses .
