During the Heian period, large shōen landed estates were established, and in the Kamakura and Muromachi period, the entire area of the city was under cultivation. During the Edo Period, due to its proximity to Kyoto and Osaka, most of the area was held as tenryō territory under the direct control of the Tokugawa shogunate.
