Tokyo Monorail

The Tokyo Monorail, officially the Tokyo Monorail Haneda Airport Line, is a straddle-beam Alweg-type monorail line in Tokyo, Japan. It provides a connection between Tokyo International Airport (Haneda) and the city's Ōta, Shinagawa, and Minato wards. The 17.8-kilometre (11.1 mi) line runs predominantly elevated along the western shore of Tokyo Bay and serves 11 stations between Hamamatsuchō and Terminal 2. The line is operated by the Tokyo Monorail Co., Ltd., a joint venture of JR East, Hitachi (the builder of the line), and ANA Holdings (the parent company of All Nippon Airways). It carried an average of 107,871 passengers per day in Japanese fiscal year 2023.

Plans for Japan's first airport rail link emerged in 1959 as Tokyo prepared to host the 1964 Summer Olympics. That year a company was created to build the line. Construction began in 1963, and service opened on 17 September 1964, 23 days ahead of the Olympic opening ceremony. The original line ran nonstop between Hamamatsuchō and Haneda Airport and was later expanded with infill stations and extensions.

The Tokyo Monorail is one of two rail lines serving the airport, alongside the Keikyū Airport Line. At Hamamatsuchō, passengers may transfer to the Keihin–Tōhoku and Yamanote lines of JR East, as well as the Asakusa and Oedo lines of the Toei Subway via nearby Daimon Station. The monorail also connects with Tokyo Waterfront Area Rapid Transit's Rinkai Line at Tennōzu Isle Station.

In November 2025, Tokyo Monorail began using the nickname Tokyo Panorama Line for its route.
