History

The area of the modern city of Takaishi was within ancient Izumi Province, and the place name "Takaishi" appears in the Nara period Nihon Shoki and other ancient works. During the Edo Period, the area was largely under the control of Kishiwada Domain. The village of Takaishi was established within Ōtori District, Osaka, with the creation of the modern municipalities system on April 1, 1889. On April 1, 1896, the area became part of Senboku District, Osaka. During the Russo-Japanese War, a large Prisoner-of-war camp was constructed on the coast of Takaishi, with an area of 430,000 square meters and a capacity to house 28,000 prisoners. The area is now a residential area. Takaishi was promoted to town status on January 1, 1915. The neighboring village of Toriishi was annexed on April 1, 1953. Takaishi was promoted to city status on November 1, 1966. The city experienced a severe financial crisis in the late 1990s and the mayor at that time attempted to merge the city with Sakai. However, the merger became the major campaign issue in the following mayoral election, and was voted down in 2003 when the incumbent mayor lost in his bid for re-election.
