Ota Ward Guide

Ota Ward is the largest of the 23 wards of Tokyo, so it can be difficult to categorize the entire area as a single type of neighborhood. You'll find neighborhoods tailored to different needs across the ward: from the high-society neighborhood of Denenchofu to the relaxed, traditional vibes of Magome and commuter-friendly Kamata.

Ota Ward is the southernmost of the 23 wards of Tokyo. It is located next to Tokyo Bay and bordered by Shinagawa, Meguro and Setagaya to the north and partly bordered by Koto Ward to the east. Haneda Airport is located in this ward, just 15 minutes away from the major hub of Kamata by bus or train.

It’s also the largest of the 23 wards and covers a lot of area: from Haneda Airport and Jonanjima on Tokyo Bay, all the way to Denenchofu and Tamagawa right next to Setagaya Ward.

Location and highlights

With Tokyo Bay to the east and the Tamagawa River to the south, a large portion of Ota Ward is close to open green parks next to water. The long riverfront pedestrian paths next to the Tamagawa River are used for jogging/cycling without having to compete for road space with cars.


One key neighborhood that is found in the western section of Ota Ward is Denenchofu. This neighborhood is one of the most exclusive, top-class neighborhoods in Tokyo. The entire neighborhood was planned with the “Garden City” concept emphasizing the connection between residents and their environment. Many of the residences in this neighborhood were modeled on western-style homes and more closely resemble grand European-style mansions than traditional Japanese-style houses. Denenchofu is also known for being an enclave for politicians, celebrities and other high-society types.


The streets around Kamata Station seem to be packed with pachinko parlors, which aren’t the most attractive establishments to walk through. However, the numerous shotengai (pedestrian shopping streets) near both JR Kamata and Keikyu Kamata Station and plentiful shopping near and inside JR Kamata (including the Tokyu Plaza), are only one reason this is a highly recommended residential hub in southern Tokyo.

The JR Station was remodeled in 2008, adding a touch of modern city living to this area. The Tokyu Station has also been undergoing redevelopments since around 2007 to improve usability and give the area a newer, cleaner look. The Tokyu Station is planned to expand to reach the Keikyu Kamata Station, so that those using the train will no longer have to disembark and transfer to get to Haneda Airport on the Keikyu Airport Line.


Just one station away from Kamata, Omori is an example of how much Tokyo can differ even across short distances. Omori has a relaxed vibe that suits a residential neighborhood. With a couple of large supermarkets near the station, Omori is thought of as a livable neighborhood for both families and single apartment hunters. Omori Station is located on the JR Keihin-Tohoku Line giving residents a direct line to business districts around Shinagawa (6 minutes away) and Tokyo (19 minutes away).
