History The ward was founded on March 15, 1947, merging the old wards of Ōmori and Kamata.

Haneda Airport, now the main domestic airport for the Greater Tokyo Area, was first established as Haneda Airfield in 1931 in the town of Haneda, Ebara District of Tokyo Prefecture. In 1945, it became Haneda Army Air Base under the control of the United States Army. In the same year, the Occupation ordered the expansion of the airport, evicting people from the surroundings on 48 hours' notice. With the end of the occupation, the Americans returned part of the facility to Japanese control in 1952, completing the return in 1958. Haneda Airport in Ōta was the major international airport for Tokyo, and handled traffic for the 1964 Tokyo Olympics.

Government The city is run by a city assembly of 50 elected members.

Geography The southernmost of the 23 special wards, Ōta borders the special wards of Shinagawa, Meguro and Setagaya to the north, and Kōtō to the east. Across the Tama River in Kanagawa Prefecture is the city of Kawasaki, forming the boundaries to the south and west.

Former operations Namco, best known for video game franchises such as Pac-Man, Galaxian, and Ace Combat, were headquartered in Ota. The company moved its operations there in 1985, using the funds generated from the successful Family Computer port of Xevious to fund the construction of its office. The building was taken over by Namco Bandai Games after it absorbed Namco in 2006, and later by an unrelated Namco company that focused on video arcades and theme parks. The newer Namco company moved out of the building in 2014 and it was demolished two years later.
