Dōshūsei(道州制?) is a proposal to organize Japan into one circuit of Hokkaido (dō) and several new states (shū) that are each a combination of several prefectures. The states and circuit are proposed to have greater regional autonomy, similar to the United Kingdom. It was first proposed[when?] by the Junichiro Koizumi administration, but has yet to materialize.
Most of the political parties in 2012 support this reform.
