There was a proposal to build a spur to Tokyo Station from the nearby Toei Asakusa Line , which would provide another connection to the subway network, and also possibly provide faster connections from the station to Tokyo's airports, Haneda and Narita .  The plan has yet to be formally adopted. Authorities are re-considering a similar plan as part of the infrastructure improvements for the 2020 Summer Olympics ; the proposed line would cut travel time to Haneda from 30 minutes to 18 minutes, and to Narita from 55 minutes to 36 minutes, at a total cost of around 400 billion yen.
