Currently, Keisei operates its Access Express service between Narita and Haneda via the Toei Asakusa Line and Keikyu Airport Line, with the journey taking about 100 minutes and requiring no surcharge. The premium express is expected to shorten travel times while offering a faster, higher-quality connection. Improving access from Narita -- Japan's primary international gateway -- to Shinagawa Station, a major interchange served by the Tokaido Shinkansen bullet train, as well as to Haneda -- the country's largest domestic aviation hub -- is expected to make it easier for overseas visitors to travel onward to regional destinations.
