Ōta, Tokyo

The ward was founded on March 15, 1947, merging the old wards of Ōmori and Kamata. The ward's name originates from the combination of letters of the two merging wards, Ōmori (大森) and Kamata (蒲田), combined into 大田 (Ōta). The ward was previously second behind Setagaya in terms of being the largest special ward in Tokyo by area, but due to land reclamation in the Tokyo Bay for the expansion of the Haneda Airport, Ōta overtook Setagaya for first place.

Haneda Airport, now one of the two main domestic and international airports serving the Greater Tokyo Area (the other one being Narita Airport in Narita, Chiba) was first established as Haneda Airfield in 1931 in the town of Haneda, Ebara District of Tokyo Prefecture. Following Japan's surrender in 1945, the airfield was turned into the Haneda Army Air Base under the control of the United States Army. In the same year, Allied occupational authorities 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 first handled international traffic for Tokyo for the 1964 Tokyo Summer Olympics. Following the opening of Narita Airport in 1978, almost all international flights (with the exception of Taiwanese airlines) moved its operations to Narita Airport. International flights resumed in 2010 following the construction of a new International terminal.

The newer Namco company moved out of the building in 2014 and it was demolished two years later.^[14]
