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. [1] As of February 2017, the city has an estimated population of 720,841 and a population density of 910 persons per km2. [2] The total area is 789.88 square kilometres (304.97 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. [3] The city is famous as the setting of the Japanese fable "Momotarō". [4]


Sengoku period to Tensho era

Okayama Castle

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.

Edo period

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

Okayama after 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 (Prefectures of Japan). Okayama became the capital of Okayama Prefecture. In 1889, Okayama City was founded. In the Meiji period, a railroad was built in Okayama city that greatly enhanced the development of the city. For example, 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 one of the most important places in western Japan for transportation and education. When World War II began, Okayama city had a Japanese Army base camp. 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. [5]

A Kibi dango, is a type of wagashi sweet or snack with an eponymous reference to Kibi-no-kuni, an old province roughly coincident with today's Okayama Prefecture. It is made by forming gyūhi, a sort of soft mochi, into flat round cakes. Glutinous rice, starch, syrup and sugar are the basic ingredients. It is manufactured by some fifteen confectioners based in Okayama City. While perhaps originally made from kibi, the modern recipe uses little or no millet, and substantively differs from kibi dango of yore, famous from the Japanese heroic folk tale of Momotarō or "Peach Boy"; nevertheless, "Kibi dango" continues to be represented as being the same as the folk hero Peach Boy's dumpling.

Kibi dango is Japanese dumpling made from the meal or flour of the kibi grain. The treat was used by folktale-hero Momotarō to recruit his three beastly retainers, in the commonly known version of the tale.
