Tainan Prefecture (臺南州/台南州 Tainan-shū?) was one of the administrative divisions of Taiwan during the Japanese rule. The prefecture consisted of modern-day Tainan City, Chiayi City, Chiayi County and Yunlin County.
In 1945 (Shōwa 20), there were 2 cities and 10 districts.
The districts are divided into towns (街) and villages (庄)
