Osaka means “large hill” and once briefly wore the imperial crown
Osaka, capital of Osaka Prefecture on Honshu’s Kansai coast, is Japan’s second-biggest prefectural city and a top-tier national metro. A Kofun-period regional port, it served briefly as imperial capital in the seventh–eighth centuries and flourished as “kitchen of the nation” in the Edo period.
Osaka, a designated city in the Kansai region of Honshu, is the capital and largest city of Osaka Prefecture and Japan's third-largest city proper after Tokyo's special wards and Yokohama. An October 2025 estimate counted about 2.8 million people at roughly 12,505 per square kilometre. It anchors the Keihanshin metropolitan area, Japan's second-largest, which with more than 19 million inhabitants ranks tenth among the world's urban areas.
Around 7,000 BCE, in the Jōmon period, most of today's city lay under water, and the Uemachi Plateau formed a peninsula 12 km long and 2.5 km wide between Kawachi Bay and the Seto Inland Sea. Fresh water, lush vegetation and a defensible position made it one of Japan's earliest settled spots. The Morinomiya ruins in Chuo-ku yielded skeletons, shell mounds, oysters, arrowheads, stone tools, fishhooks and pottery bearing traces of rice processing, with debris about 2,000 years old spanning the Jōmon and Yayoi eras.
By the Kofun period (300–538) the site was a significant regional harbour, and it briefly hosted the imperial court in the seventh and eighth centuries. It thrived as a cultural centre during the Edo period (1603–1867), then swelled and industrialised after the Meiji Restoration, leading Japanese industry through the Meiji and Taishō eras. The name, meaning "large hill" or "large slope", is first written in 1496, though when it eclipsed Naniwa is unclear. Two kanji spellings coexisted in Edo times; in his 1808 book Setsuyo Ochiboshu, Hamamatsu Utakuni said 坂 was shunned because it suggested "returns to the earth" or even "samurai rebellion", and 阪 became official in 1868.
Today Osaka is a leading financial centre and one of Japan's most multicultural cities, home to the Osaka Exchange and to the headquarters of Panasonic and Sharp. Osaka University, Osaka Metropolitan University and Kansai University anchor its research. Visitors head for Osaka Castle, the Kaiyukan aquarium, the Dōtonbori strip, Shinsekai's Tsūtenkaku tower, the Abeno Harukas skyscraper, Tennōji Park, the Sumiyoshi Taisha shrine and Shitennō-ji, one of Japan's oldest Buddhist temples.
