Okayama (岡山市, Okayama-shi, Japanese: [okaꜜjama]) is the capital city of Okayama Prefecture in the Chūgoku region of Japan. The city was founded on June 1, 1889. As of February 2023[update], the city has an estimated population of 700,940 and a population density of 890 persons per km2. The total area is 789.95 square kilometres (305.00 square miles).
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.
The city of Okayama is located in the southern part of Okayama Prefecture, which is located in western part of the island of Honshū. The northern part of the city forms a corner of Kibi Plateau, which is a series of gentle hills, and includes the Asahikawa Dam, Okayama Airport, and a suburban residential area. The central urban area is located on the Okayama Plain in the south, which was formed by the transportation and sedimentation of two first-class rivers, the Asahi River and Yoshii River, which flow into the Seto Inland Sea. To the south of the main urban area is Kojima Bay, which forms the scenic Kojima Peninsula overlooking the Seto Inland Sea.
Okayama has a mild climate in comparison to most of Japan. It has the most rain-free days (less than 1mm of precipitation) of any city in Japan. It is ranked as the second driest and the fourth sunniest city in the Chūgoku region. The climate is classified under the Köppen climate classification as humid subtropical (Cfa).
The local climate is warm enough throughout the year to support olive trees. Okayama is often called "Land of Sunshine" because of its low number of rainy days per year.

Per Japanese census data, the population of Okayama is as follows:
Sengoku period to Bakumatsu period
Before the Muromachi period, Okayama was one corner of a farm region and included a small castle built by the Kanemitsu. In the Sengoku period, Ukita Naoie attacked Okayama and attacked the castle for the transportation resources and extensive farmland in the region. Naoie remodeled the castle, built the old Sanyo road to the central part of the castle town, and called in craftsmen both from inside and outside of Bizen Province. Okayama became the political and economical capital of Bizen Province.
In 1600, Ukita Hideie, who was the son of Naoie and the lord of Okayama, lost at the Battle of Sekigahara. The next year, Kobayakawa Hideaki came to Okayama and became the feudal lord of Okayama Domain. Hideaki died in 1602, however, ending the Kobayakawa line. Ikeda Tadatugu, who was the feudal lord of Himeji Domain, became the next lord of Okayama. After this time, Okayama was ruled by the Ikedas until the latter part of the 19th century. Continuing its economic development, Okayama became one of the ten best large castle towns in Japan in the 18th century. The Korakuen Garden was developed by the fourth feudal lord, Ikeda Tsunamasa.
Meiji Restoration 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. Okayama became a center in western Japan for transportation and education. When World War II began, Okayama city was a garrison city for the Imperial Japanese Army. On June 29, 1945, the city was attacked by the US Army Air Forces with incendiary bombs. Almost all the city was burned, and more than 1700 people were killed. Okayama suffered terrible damage in the war, losing more than 12,000 households.
Since World War II
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.
Okayama has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 46 members. The city contributes 19 members to the Okayama Prefectural Assembly. In terms of national politics, the city is divided between of the Okayama 1st District, Okayama 2nd District and Okayama 3rd District of the lower house of the Diet of Japan.
Since Okayama became a designated city in 2009, the city has been divided into four wards (ku).
