Etymology

''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, (''Ōsaka'') and (''Ōsaka'') were mixed use, and the writer , in his book ''Setsuyo Ochiboshu'' published in 1808, states that the kanji was abhorred because it "returns to the earth," and then was used. The kanji (earth) is also similar to the word (knight), and means against, so can be understand as "samurai rebellion," then was official name in 1868 after the Meiji Restoration. The older kanji (坂) is still in very limited use, usually only in historical contexts. As an abbreviation, the modern kanji refers to Osaka City or Osaka Prefecture.

History

Origins: Jōmon and Yayoi period

In the Jōmon period (7,000 BCE), Osaka was mostly submerged by the Seto Inland Sea, and the small Uemachi-daichi plateau (12 km long and 2.5 km wide), located in the southern part of the city called Uehonmachi, was a peninsula. The Uehonmachi area consisted of a peninsula with an inland sea (Seto Inland Sea) in the east. 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 it was in a position difficult to attack from a military point of view.

The earliest evidence of settlements in the Osaka area are the 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 archaeological 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-daichi peninsula / plateau transformed the sea that stretched to the east into a lagoon which was called Kawachi. During the Yayoi period (300 BCE-250 CE), permanent habitation on the plains grew as rice farming became popular.
