Archaeologists have found kofun along the banks of the Tama River and at other locations in the Ward. Under the Nara period Ritsuryō system, it was divided between Tachibana District, Tama District and Tsutsuki District in Musashi Province. By the Heian period it was part of a shōen controlled by the Inage clan. By the Kamakura period, it was controlled by their descendants, the Ozawa clan, and in the Muromachi period by the Terao clan. During the Sengoku period, the area was a contested territory between the Uesugi clan and the Later Hōjō clan from Odawara, who emerged in control by 1530. The area was devastated by flooding when the Tama River shifted course to the north in 1590. After the defeat of the Hōjō at the Battle of Odawara, the territory came under the control of Tokugawa Ieyasu. It was administered as tenryō territory controlled directly by the Tokugawa shogunate, but administered through various hatamoto. From 1725, the 52 villages of the area were a designated zone for Falconry by the Tokugawa shōguns, but suffered from repeated natural disasters: an earthquake in 1782, floods in 1786, famine in 1787, floods in 1790, 1791 and 1809 and earthquake in 1855. After the Meiji Restoration, the area was transferred to the new Kanagawa Prefecture, and divided into several villages within Tachibana District and Tsuzuki District, Kanagawa on April 1, 1889. These areas were annexed by the neighboring city of Kawasaki from 1938–1939. The area became Tama Ward with the division of the city of Kawasaki into wards from April 1972.
