Haneda Airport
Haneda Airport was significantly expanded with a new terminal in 1993, and Keikyu received government permission to serve the new terminal as the monorail alone was deemed to have inadequate capacity. From 18 November 1998, the Airport Line was extended from Tenkūbashi to Haneda Airport Station (present-day Haneda Airport Domestic Terminal Station), allowing direct service between the airport and major stations such as Shinagawa and Yokohama. Haneda Airport International Terminal Station opened on 21 October 2010.
