History

The area of the modern city of Izumiōtsu was within ancient Izumi Province, and was the site of the port for the provincial capital of the province. During the Yayoi period it was a stronghold of the Mononobe clan and the place name of "Ōtsu" appears in the Nara period Nihon Shoki, the Heian period Sarashina Nikki and other works. In the Edo Period, the area was controlled by Hakata Domain or as tenryō territory of the Tokugawa shogunate administered by Kishiwada Domain. The village of Ōtsu was established within Izumi District with the creation of the modern municipalities system on April 1, 1889. On April 1, 1896 the area became part of Senboku District, Osaka. Ōtsu was promoted to town status on April 1, 1915 and to city status on April 1, 1942. To avoid confusion with the city of Ōtsu, Shiga, the city name was chosen to be "Izumiōtsu".

Government

Izumiōtsu has a mayor-council form of government with a directly elected mayor and a unicameral city council of 16 members. Izumiōtsu collectively with the city of Takaishi and the town of Tadaoka contributes two members to the Osaka Prefectural Assembly. In terms of national politics, the city is part of Osaka 18th district of the lower house of the Diet of Japan.

Economy

The textile industry has been important to Izumiōtsu since the Edo period, and the city still commands more than 90% of the domestic cotton blanket market. The port was also modernized in the early 20th century and occupies a part of the Sakai Senboku coastal industrial area. Sumitomo Rubber Industries, a major producer of automobile tires, is also a major employer.
