History
[edit]The Kasaoka area is part of ancient Bitchū Province and numerous shell middens from the Jōmon period confirm that the area has been inhabited since prehistoric times. The place name 'Kasaoka' is said to have been derived from the area of influence of the 'Kasaomi clan' of the ancient Kingdom of Kibi. Kasaoka Castle, was built by Murakami Takashige at the end of the Muromachi period and was controlled by the Mōri clan during the Sengoku period. Under the Edo Period Tokugawa shogunate, the area became part of the territory of the Mizuno clan of Fukuyama Domain. The Mizuno invested vast sums of money in civil engineering projects to promote the development of new rice fields in Kasaoka, which originally had little flat land. However, the domain fell to attainder in the middle of the Edo period, and the Kasaoka area was ruled as tenryō territory about 170 years until the end of the Edo period.
Following the Meiji restoration, the village of Kasaoka was established within Oda District, Okayama with the creation of the modern municipalities system on June 1, 1889. It was raised to town status on October 23, 1891 and to city status on April 1, 1952. Due to its strong historical, cultural and economic ties with Fukuyama, proposals have been made for a merger between the two municipalities.
Government
[edit]Kasaoka has a mayor-council form of government with a directly elected mayor and a unicameral city council of 17 members. Kasaoka contributes two members to the Okayama Prefectural Assembly. In terms of national politics, the city is part of the Okayama 3rd district of the lower house of the Diet of Japan.
Economy
[edit]Kasaoka is located in the Seto Inland Sea Industrial Belt and together with neighboring Fukuyama was designated in 1964 as the "Bingo District Special Industrial Development Area". The city has a high concentration of heavy industry, notably related to JFE Steel, a major producer of crude steel in Japan. Agriculture, food processing are also major contributors to the local economy, although the traditional industries stone quarrying and production of pyrethrum are in decline due to competition from foreign sources. The city is also increasing a commuter town for neighboring Fukuyama and Kurashiki.
Education
[edit]Kasaoka has 18 public elementary schools and nine public junior high schools operated by the city government and one private junior high school. The city has four public high schools operated by the Okayama prefectural Board of Education. The prefecture also operates one special education school for the disabled.
