Komae is nestled between the Tama River to the southwest, and the much smaller Nogawa River to the north and east which flows near its boundaries with Chōfu city and Setagaya Ward. It is mostly flat. It is a small municipality; its boundaries fit within a circle of 2 km radius centred on the city hall. It is essentially a residential suburb of Tokyo which urbanised rapidly in the 1960s and 1970s, with most of the working population commuting to central Tokyo. There are several neighbourhood shopping areas, mainly around the train stations. The City Hall is located near Komae Station.

The city's name is thought to originate from the word koma, referring to migrants, especially Goguryeo from the Korean peninsula who settled here around the 5th century AD. [4] [5] [6] Numerous kofun burial mounds are located within the city borders.

The area of present-day Komae was part of ancient Musashi Province. In the post- Meiji Restoration cadastral reform of July 22, 1878, the area became part of Minamiitama District in Kanagawa Prefecture. The town of Komae was created on April 1, 1889 with the establishment of the modern municipalities system. Minamtama District was transferred to the administrative control of Tokyo Metropolis on April 1, 1893. Odakyu Railways's Odawara line was constructed through Komae in 1926, linking it with Shinjuku in central Tokyo. Expanding population led to Komae being upgraded to the status of a town in 1952, and to a city on October 1, 1970.

On September 1, 1974, Tama River's levee failed during a typhoon, and 19 houses were destroyed by torrential flooding. The riverbanks have now been strengthened. A small memorial stands at the location of the levee failure.


Komae has a mayor-council form of government with a directly elected mayor and a unicameral city council of 26 members. The current mayor is Kunihiko Takahashi, an independent heading a coalition of the Democratic Party of Japan with the Liberal Democratic Party of Japan and the Komeito, which ousted long-term Japanese Communist Party mayor Yutaka Yano in 2012. Komae, together with the city of Chōfu, contributes three members to the Tokyo Metropolitan Assembly. In terms of national politics, the city is part of Tokyo 26th district of the lower house of the Diet of Japan.


The one public high school, Komae High School, is operated by the Tokyo Metropolitan Government Board of Education.

Komae has six public elementary schools and four junior high schools schools operated by the city.

Korean cultural words such as fude (writing brush), tefu (notebook), and even place names such as Koma, Komae and Rebonri, and the most prominent, Nara ("country" in Korea), were introduced into Japan around that time.
