As of 21 October 2012, the station structure has three levels. Up trains (to Shinagawa and Haneda Airport) depart from the second level, down trains (to Yokohama and Misakiguchi) and Haneda Airport depart from the third level.
Platforms
The 3rd floor consists of one large platform serving three tracks in a unique configuration. Platforms 1 and 4 are equipped with platform screen doors.[2]
The station opened on 1 February 1901 as Kamata Station (蒲田駅).[3] The Airport Line (then called the Haneda Branch Line) was opened in 1902. Kamata Station was renamed Keihin Kamata Station (京浜蒲田駅) in November 1925, and again renamed Keikyū Kamata Station, the present name, on 1 June 1987.[3]
In 1995, the platforms were extended to accommodate longer 12-car trains.[4]
The station was rebuilt over a period of 12 years from December 2000 to October 2012 with the original ground-level tracks elevated to provide additional track capacity and eliminate road congestion on the three level crossings immediately adjacent to the station.[5] As a result, the project won the Good Design Award presented by the Japan Institute of Design Promotion.[6]
Keikyu introduced station numbering to its stations on 21 October 2010; Keikyū Kamata was assigned station number KK11.[7]
Future plans
Plans exist to extend the Tokyu Tamagawa Line from Kamata Station eastward by approximately 800 m to Keikyu Kamata Station. This would provide an interchange between the lines, improving accessibility to Tokyo's Haneda Airport ahead of the 2020 Summer Olympics.[8] These plans never materialized before the Olympics. As of June 2022[update], Ōta Ward has agreed with the Tokyo Metropolitan Government to pay 70% of the project cost of ¥136 billion (2021) (US$1.24 billion) while having the city government responsible for the remaining 30%.[9]
