City Office

Ōta (大田区, Ōta-ku) is a special ward in the Tokyo Metropolis in Japan. In English, it is often called Ōta City.

As of June 1, 2016, the ward has an estimated population of 716,413, with 379,199 households and a population density of 12,048.65 persons per km2. The total area is 59.46 km2, the largest of the special wards.

Ōta's hub is situated around the two stations Kamata and Keikyū Kamata, where the Ōta Ward Office and central Post Office can be found.

Districts and neighborhoods[edit]


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.

Politics and government[edit]

The city is run by a city assembly of 50 elected members. The current mayor is Akimasa Suzuki.


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.

The following companies have their headquarters in Ōta.

Former operations[edit]

Namco, best known for video game franchises such as Pac-Man, Galaxian, and Ace Combat, were headquartered in Ota.[12] 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.[13][14] 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.[13]

Prior to the merger with Japan Airlines,[15] Japan Air System had its headquarters by Tokyo International Airport in Ōta.[16]

In 2000 All Nippon Airways was headquartered by Tokyo International Airport in Ōta.[17] In 2002 Air Nippon was headquartered on the fifth floor of the Utility Center Building (ユーティリティセンタービル, Yūtiriti Sentā Biru) by Tokyo International Airport in Ōta.[18] The ANA subsidiary Air Nippon Network was also based at the airport.[19]

Before its dissolution, Galaxy Airlines was headquartered in the ARC Building on the airport grounds.[20]

Sega and its parent company Sega Sammy Holdings, best known for its Sonic the Hedgehog franchise, was originally headquartered in Ota. However, Sega Sammy Holdings announced in April 2017 that it would relocate its head office functions and domestic subsidiaries to Shinagawa-ku by January 2018. This was to consolidate scattered head office functions including Sega Sammy Holdings, Sammy Corporation, Sega Holdings, Sega Games, Atlus, Sammy Network, and Dartslive. After the relocation to Shinagawa-ku was complete, Sega's previous headquarters in Ōta was later sold in February 2019 and will likely be torn down.

Gakken was headquartered in Ota from 1962 until 2008 when they moved their headquarters to Shinagawa-ku.[21]
