Ōta is located in the extreme southeastern portion of Gunma Prefecture in the northern Kantō Plains, bordered by Tochigi Prefecture to the east and Saitama Prefecture to the south. The city is located northwest of Tokyo between the Tone and Watarase rivers.
During the Edo period, the area of present-day Ōta contained two post towns on the Nikkō Reiheishi Kaidō, a subroute to Nikkō Kaidō which connected the Nakasendō directly with Nikkō, bypassing Edo., the Ōta-shuku, and Kizaki-shuku. Modern Ōta Town was created within Nitta District, Gunma Prefecture on April 1, 1889 with the creation of the municipalities system after the Meiji Restoration. On April 1, 1940, Ōta merged with the villages of Kuai and Sawano from Nitta District, and with the village of Niragawa from Yamada District. On November 1, 1943, Ōta absorbed the village of Shimanogō, also from Nitta District. Ōta was elevated to city status on May 3, 1948. The city expanded on April 1, 1957, by annexing the village of Kyodo, and the village of Kyūhaku, and by annexing parts of the village of Yabakawa on July 1, 1960. On April 1, 1963, Ōta absorbed the village of Hosen, followed by the village of Kesatoda on December 1, 1963. On March 28, 2005, the old city of Ōta absorbed the towns of Nitta, Ojima, and Yabuzukahon, and the area became the new city of Ōta. The former city of Ōta had a population of 152,000, with a total area of 97.96 km²; after the merger the total area became 176.49 km², and the population went to 217,000 people. On April 1, 2007, Ōta was designated special city with expanded local autonomy.
