Culture & Daily Life
📜 History & Origins
The area has been a major political and trading centre since the 5th century, when the Naniwa-no-Miya palace was established here. Osaka Castle was built by warlord Toyotomi Hideyoshi in 1583, transforming the area into a major political and commercial capital. The modern municipality was established in 1889 and the city served as Japan's largest and most populous city in 1925, before ceding that position back to Tokyo.
