is a prefecture located in the Kansai region on Honshu, the main island of Japan. The capital is the city of Osaka. It is the center of Osaka-Kobe-Kyoto area. Osaka Prefecture is one of the two urban prefectures of Japan, Kyoto Prefecture being the other (Tokyo is considered a "metropolitan prefecture" rather than an urban prefecture).
Osaka Prefecture was created on June 21, 1868, at the very beginning of the Meiji era. During the instigation of Fuhanken Sanchisei in 1868, the prefecture received its suffix fu, designating it as an urban prefecture.
In 2008, Tōru Hashimoto, previously famous as a counselor on television, was elected at the age of 38 as the youngest governor in Japan.
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.
