It was formed in 2000 from the western portion of the Tōkyū Mekama Line, which was then rerouted west of Tamagawa (former Tamagawa-en) station and renamed the Meguro Line.

This line should not be confused with the Tokyu Shin-Tamagawa Line (a section of track from Shibuya to Futako-tamagawa, (which has since been absorbed into the Tokyu Den-en-Toshi Line), or the Tamagawa Line tramway which preceded that (of which one of its branches now forms the Setagaya Line).

History

The Tokyu Tamagawa Line was formed on 6 August 2000 with the splitting of the former Tokyu Mekama Line.^[1] Wanman driver-only operation also commenced on the line from this date.^[1]

Future plans

Main article: Kama-Kama Line

Plans exist to extend the line eastward by approximately 800 m from the southern terminus of the line at Kamata to Keikyu Kamata Station on the Keikyu Main Line and Keikyu Airport Line, a project known as the Kama-Kama Line. This would provide an interchange between the lines, improving accessibility to Tokyo's Haneda Airport ahead of the 2020 Summer Olympics.^[2] The plans did not materialize in time for the 2020 Summer 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%.^[3]
