Osaka
Osaka (Japanese: 大阪市, Hepburn: Ōsaka-shi; pronounced [oː.sa.kaꜜ.ɕi]; commonly just 大阪, Ōsaka [oː.sa.ka] ⓘ) is a designated city in the Kansai region of Honshu in Japan. It is the capital of and most populous city in Osaka Prefecture, and the third-most populous city in Japan, following the special wards of Tokyo and Yokohama. With an estimated population of 2,816,247 as of October 1, 2025 and a population density of about 12,505 people per square kilometer, it is the largest component of the Keihanshin Metropolitan Area, which is the second-largest metropolitan area in Japan and the 10th-largest urban area in the world with more than 19 million inhabitants.
Ōsaka was traditionally considered Japan's economic hub. By the Kofun period (300–538) it had developed into an important regional port, and in the 7th and 8th centuries, it served briefly as the imperial capital. Osaka continued to flourish during the Edo period (1603–1867) and became known as a center of Japanese culture. Following the Meiji Restoration, Osaka greatly expanded in size and underwent rapid industrialization. The construction boom accelerated population growth throughout the following decades, and by the 1900s, Osaka was the industrial hub in the Meiji and Taishō eras. Osaka made noted contributions to redevelopment, urban planning and zoning standards in the postwar period, and the city developed rapidly as one of the major financial centers in the Keihanshin Metropolitan Area.
Osaka is a major financial center of Japan, and it is recognized as one of the most multicultural and cosmopolitan cities in Japan. The city is home to the Osaka Exchange as well as the headquarters of multinational electronics corporations such as Panasonic and Sharp. Osaka is an international center of research and development and is represented by several major universities, notably Osaka University, Osaka Metropolitan University, and Kansai University. Famous landmarks in the city include Osaka Castle, Osaka Aquarium Kaiyukan, Dōtonbori, Tsūtenkaku in Shinsekai, Tennōji Park, Abeno Harukas, Sumiyoshi Taisha Grand Shrine, and Shitennō-ji, one of the oldest Buddhist temples in Japan.
Ōsaka means "large hill" or "large slope". It is unclear when this name gained prominence over Naniwa, but the oldest written evidence for the name dates back to 1496.
By the Edo period, 大坂 (Ōsaka) and 大阪 (Ōsaka) were mixed use, and the writer Hamamatsu Utakuni, in his book Setsuyo Ochiboshu published in 1808, states that the kanji 坂 was abhorred because it means "returns to the earth," and thus 阪 was used. The kanji 土 (earth) is also similar to the word 士 (knight), and 反 means against, so 坂 can be understood as "samurai rebellion."[citation needed] 阪 became the official name in 1868 after the Meiji Restoration. The older kanji (坂) is still in very limited use, usually only in historical contexts. When used as an abbreviation, the modern kanji 阪 han refers to Osaka City or Osaka Prefecture.
During the Jōmon period (7,000 BCE), present-day Osaka was mostly submerged, and the Uemachi Plateau (上町台地, Uemachi Daichi) formed a 12 km long and 2.5 km wide peninsula separating Kawachi Bay from the Seto Inland Sea. It is considered one of the first places where inhabitants of Japan settled, both for the favorable geological conditions, rich in fresh water and lush vegetation, and because its position was defensible against military attack.
The earliest evidence of settlements in the Osaka area are the Morinomiya ruins (森ノ宮遺跡, Morinomiya iseki) which is located in the central Chuo-ku district. Buried human skeletons and a kaizuka (a mound containing remains) were found, as well as shell mounds, oysters, and other interesting archeological discoveries from the Jomon period. In addition to the remains of consumed food, there were arrow heads, stone tools, fishing hooks and crockery with remains from rice processing. It is estimated that the ruins contain 2,000-year-old debris between the Jomon and Yayoi period. The findings of the archeological sites are exhibited in an adjacent building.
In the years between the end of the Jōmon period and the beginning of the Yayoi period, the sediments that were deposited north of the Uemachi peninsula / plateau transformed Kawachi Bay into a lagoon. During the Yayoi period (300 BCE-250 CE), permanent habitation on the plains grew as rice farming became popular.
