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. 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
Minamitama District in
Kanagawa Prefecture. The town of Komae was created on April 1, 1889, with the establishment of the modern municipalities system. Minamitama 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. ==Government==
