Osaka
is the third largest city in Japan, with a population of around 2.5
million. Since feudal times, Osaka has been the economic center of the
Kansai region.
Osaka was once known as Naniwa,
and was briefly the capital of Japan. (In ancient times, the capital was
moved to a new location with the death of each emperor.)
One of the most famous sights in
Osaka is Osaka Castle. The castle was built by Toyotomi Hideyoshi in the
16th century. Hideyoshi was then Japan’s most powerful warlord,
and Osaka might have eventually become Japan’s capital.
After Hideyoshi died, however, the
warlord Tokugawa Hideyasu (Hideyoshi’s former subordinate) forced
Hideyoshi’s son to commit suicide. Ieyasu subsequently founded the
Tokugawa shogunate, and moved his headquarters to Edo (later Tokyo). Edo
therefore became the de facto center of power in Japan.
