The area of present-day Kyonan was part of ancient Awa Province. The villages of Katayama and Ota were established with the creation of the modern municipalities system on April 1, 1889. Katsuyama was raised to town status in January 1896 and Hota in January 1897. The town of Kyonan was formed by the merger of Katsuyama and Hota on March 30, 1959. With the creation of the city of Minamibōsō in 2006, Kyonan is the only remaining unincorporated portion of Awa District.


Kyonan has a mayor-council form of government with a directly elected mayor and a unicameral town council of 12 members. Kyonan, together with the city of Minamibōsō, contributes one member to the Chiba Prefectural Assembly. In terms of national politics, the city is part of Chiba 12th district of the lower house of the Diet of Japan.


Kyonan serves as a commercial center for the surrounding region of southwest-central Chiba Prefecture. The primary industry is commercial fishing and agriculture (rice and flowers). Mount Saga has been used for narcissus cultivation at least from the Edo period 1603–1868, and Kyonan remains one of the largest producers of the flower in Japan.[4] The tourist industry is a growing component of the local economy.


Kyonan has one public elementary school and one public middle school operated by the town government. The town does not have a high school; however, the Chiba Prefectural Board of Education operates one special education school for the handicapped.
