The Japanese political process has three types of elections.
Prefectural elections for the Tokyo Metropolitan Assembly were held on 12 July 2009.

The Osaka Restoration Association, also referred to as One Osaka, is a regional political party in Osaka Prefecture, Japan. Founded in 2010 by then-Governor Tōru Hashimoto, its main platform is pursuing the Osaka Metropolis plan of merging the prefecture and some of its cities into "One Osaka", reducing overlapping bureaucratic organizations of the prefecture and the city of Osaka, towards Dōshūsei.
