Okayama岡山県
Okayama Prefecture (岡山県, Okayama-ken) is a prefecture of Japan located in the Chūgoku region on the main island of Honshu. The capital is the city of Okayama. Prior to the Meiji Restoration of 1868, the area of present-day Okayama Prefecture was divided between Bitchū, Bizen and Mimasaka Provinces. Okayama Prefecture was formed and named in 1871 as part of the large-scale administrative reforms of the early Meiji period (1868 – 1912), and the borders of the prefecture were set in 1876.
