The city is the site of Kōraku-en, known as one of the top three traditional gardens in Japan, and Okayama Castle, which is ranked among the best 100 Japanese castles. The city is famous as the setting of the Japanese fable Momotarō. Okayama joined the UNESCO Global Network of Learning Cities in 2016.

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 Sixth Higher Middle School (第六高等学校, Dairoku Kōtōgakkō) and Okayama Medical College (岡山医科大学, Okayama Ika-daigaku) were established in Okayama City.

With modern state formation, the city developed as a regional hub for transport and education in western Japan.

When World War II began, Okayama city was a garrison city for the Imperial Japanese Army. During the war, the city was bombed by the American forces. On 29 June 1945, air raids burned much of the urban core; the castle keep was lost. More than 1700 people were killed.

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.

During Japan's economic boom of the 1960s, Okayama developed rapidly as one of the most important cities in the Chūgoku and Shikoku regions. In 1972, the San'yō Shinkansen began service between Shin-Ōsaka and Okayama stations. Two years later, Shinkansen service was extended to Hakata. In 1988, the Seto-Ōhashi Bridge was opened, and connected Okayama with Shikoku directly by rail and road.

The city became a core city in 1996 and a designated city on April 1, 2009, with increased local autonomy.

On March 22, 2005, the town of Mitsu (from Mitsu District), and the town of Nadasaki (from Kojima District) were merged into Okayama. This was followed on January 22, 2007, when the town of Takebe (from Mitsu District), and the town of Seto (from Akaiwa District) were merged into Okayama. Kojima, Mitsu, and Akaiwa Districts have all since been dissolved as a result of these mergers.
