Ōta City is one of the special wards of Tokyo, Japan, located in the southeastern part of the metropolis, facing Tokyo Bay. Historically, it has been a thriving fishing area; during the Taisho era, it gradually developed into a hub for small workshops, eventually forming what is now the Keihin Industrial Zone. The ward is home to Tokyo International Airport (Haneda Airport), serving as a major gateway to the city.
Part of the well-known upscale residential area "Den-en-chōfu" is located on the western side of Ōta City.
Ōta City sits in the southeastern corner of Tokyo and is the southernmost of Tokyo's 23 special wards. The eastern side includes Haneda Airport, which occupies about one-third of the entire area. Ōta was formed from the merger of the former Ōmori and Kamata wards. Today, commercial activities are mainly centered around Ōmori Station and Kamata Station, with the administrative center located near Kamata Station. While Ōta is relatively far from the city center compared to other wards, it still lies within a 15-kilometer radius of central Tokyo and shares the same living zone as places like Kichijōji, Kawaguchi, Matsudo, and Ichikawa. Across the Tama River lies Kawasaki City in Kanagawa Prefecture.
