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.,[2] the Ōta-shuku (太田宿), (from which the city takes its name) and Kizaki-shuku (木崎宿).[1]

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 (from Nitta District), and the village of Kyūhaku (from Yamada District), and by annexing parts of the village of Yabakawa (Yamada District) on July 1, 1960. On April 1, 1963, Ōta absorbed the village of Hosen (Nitta District), followed by the village of Kesatoda (Yamada District) on December 1, 1963.

On March 28, 2005, the old city of Ōta absorbed the towns of Nitta, Ojima, and Yabuzukahon (all from Nitta District), 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 (tokureishi) with expanded local autonomy.


During the years before World War II, airplane production was the industrial mainstay of Ōta. After the war, much of the skills and technology used in the production of aircraft was redirected into the production of automobiles. Ōta's leading industry is manufacturing, centered in the southeast part of the city. Ōta leads the prefecture in manufacturing revenue, which exceeds ¥1.3 trillion annually. It is the home of the car manufacturer Subaru, a subsidiary of Subaru Corporation (株式会社SUBARU?, Kabushiki-gaisha Subaru), formerly known as Fuji Heavy Industries, Ltd. (富士重工業株式会社?, Fuji Jūkōgyō Kabushiki-gaisha, FHI). Subaru-chō is where the Subaru BRZ/Toyota 86 is built, having been re-purposed from kei car production, Yajima Plant is where all current Subaru cars are built, Otakita Plant is where commercial kei trucks are built (originally the location of Nakajima Aircraft), and Oizumi Plant is where engines and transmissions are built.[3]

The northern part of Ōta is characterized by its farms, most of which produce rice. Also, Ōta is a major transportation hub in the Tomo (Eastern Gunma) region and the home of the Panasonic Wild Knights rugby team.[citation needed]


There are seven public and two private high schools, 17 public middle schools, 26 public elementary schools, and three private schools in Ōta.
