Until the Meiji Restoration, the area of Osaka prefecture was known as Kawachi, Izumi,[4][5] and Settsu provinces.[6]

Osaka Prefecture was created on June 21, 1868, at the very beginning of the Meiji era.[7] During the instigation of Fuhanken Sanchisei in 1868, the prefecture received its suffix fu, designating it as an urban prefecture.

On September 1, 1956, the city of Osaka was promoted to a city designated by government ordinance and thereby divided into 24 wards.

In 2000, Fusae Ota became Japan's first female governor when she replaced Knock Yokoyama, who resigned after prosecution for sexual harassment.[8]

In 2010, the Osaka Restoration Association was created with backing by Governor Tōru Hashimoto, attempting to reform Osaka Prefecture into Osaka Metropolis reducing affiliated organizations of Osaka Prefecture and the City of Osaka.

In the 2011 local elections the association was able to win the majority of the prefectural seats.

The plan was narrowly defeated in the 2015 referendum (49.62% yes and 50.38% no).


Osaka Prefecture neighbors the prefectures of Hyōgo and Kyoto in the north, Nara in the east and Wakayama in the south. The west is open to Osaka Bay. The Yodo and Yamato Rivers flow through the prefecture.

Further downstream, the Seta flows into Kyoto Prefecture and changes its name to the Uji River, and then merges with two other rivers, namely the Katsura River and the Kizu River in Kyoto Prefecture. The Katsura has its headwaters in the mountains of Kyoto Prefecture, while the Kizu comes from Mie Prefecture. From the three-river confluence, the river is called the Yodo River, which flows south, through Osaka, and on into Osaka Bay. In Osaka, part of the river has been diverted into an artificial channel; the old course in the heart of Osaka is called the Kyū-Yodo River (literally, 'Former Yodo River').

It serves as a source of water for irrigation and also powers hydroelectric generators.
