The Haneda Airport Access Line (羽田空港アクセス線, Haneda-kūkō akusesu-sen) is a commuter rail line under construction by the East Japan Railway Company (JR East) that will link Haneda Airport to central Tokyo.
[2][3] Two further branches are proposed to connect the airport west towards Osaki and Shinjuku, and east towards Shin-Kiba along the Rinkai Line.
Due to the growing demand of air travelers using Haneda Airport, especially international travelers, JR East officially announced in the “JR East Group Management Vision V” issued in 2013 that they aimed to improve the accessibility to the airport.
[4] In 2014, JR East released its fundamental construction plan for the accessibility improvement.
[8] In 2021, JR East announced that they have received Ministry of Land, Infrastructure, Transport and Tourism approval for construction of the East Yamanote route and intended to start construction in 2022, for completion by 2029.
