History Sengoku to Edo period

In the late 16th century, during the Sengoku period (also called the Warring states period), Ukita Naoie consolidated a stronghold at Ishiyama beside the Asahi River. His successor, Ukita Hideie, shifted the main enclosure to the hill called "Okayama" and completed Okayama Castle, traditionally dated to 1597; hydrological works redirected river channels to serve as moats, and a castle town was laid out on a north–south axis. After the Battle of Sekigahara, Kobayakawa Hideaki became the lord of the Okayama Domain and reconfigured the outer defenses, including the Hatsuka-bori (an outer moat reputedly finished in twenty days) and gates that defined the city's perimeter. Ikeda Tadatugu, who was the feudal lord of Himeji Domain, became the next lord of Okayama. The Ikeda clan subsequently ruled Okayama and expanded the castle town.

Meiji period to World War II

On August 29, 1871, the new Meiji government of the Empire of Japan replaced the traditional feudal domain system with centralized government authority. Okayama became the capital of Okayama Prefecture. In 1889, Okayama City was founded with the establishment of the modern municipalities system. In the Meiji period, a San'yo Main Line railroad and other local lines greatly enhanced the development of the city. The and were established in Okayama City.

After the war

Postwar rebuilding reestablished the central districts on the former castle-town grid. Landmarks of the modern center include the Yanagawa rotary (1959) and large-scale redevelopment in Nakasange continuing into the 21st century. Okayama Castle's keep was reconstructed in 1966, restoring the “Ujō” (“Crow Castle”) silhouette above the Asahi River.
