Okayama Domain (Japan)

Okayama Domain (岡山藩, Okayama-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, in what is now eastern Okayama Prefecture on the island of Honshu. It controlled all of Bizen Province and a small portion of Bitchū Province was centered around Okayama Castle, and was ruled throughout its history by a branch of the Ikeda clan. Okayama Domain was dissolved in the abolition of the han system in 1871 and is now part of Okayama Prefecture. Okayama Domain had two sub-domains, Kamogata Domain (鴨方藩) and Ikusaka Domain (生坂藩). In addition, six of the clans who served as hereditary karō of the domain had kokudaka equivalents to that of daimyō.
