The Keisei Electric Railway Company, Ltd.[2] (stylized as K'SEI since 2001) is a major private railway in Chiba Prefecture and Tokyo, Japan. The name Keisei is the combination of the kanji 京 from Tokyo (東京, Tōkyō) and 成 from Narita (成田, Narita), which the railway's main line connects. The combination uses different readings than the ones used in the city names. The railway's main line runs from Tokyo to Narita and the eastern suburb cities of Funabashi, Narashino, Yachiyo, and Sakura. Keisei runs an airport limited express train called the Skyliner from Ueno and Nippori to Narita International Airport.

In addition to its railway business, the Keisei Electric Railway Company owns large bus and taxi services and some real estate holdings. It owns a large, controlling, share of the Oriental Land Company which owns and manages the Tokyo Disney Resort. Keisei is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 index.[3]


Keisei was founded on June 30, 1909 and began services on November 3, 1912, initially operating local train service in eastern Tokyo. Its main line reached Narita in 1930 and Ueno in 1933.[4]

Originally a narrow gauge (1,372 mm or 4 ft 6 in Scotch gauge) operator, Keisei converted to 1,435 mm (4 ft 8+12 in) standard gauge in 1959. In 1960, Keisei began through service with the Toei Asakusa Line, the first interline through service arrangement in Japan.[4]

Skyliner service began in 1973 and started serving the airport in 1978, when the first Narita Airport Station opened (today's Higashi-Narita station). A new underground station was opened in 1991 to provide a more direct connection to terminal 1, and in 1992 service began to terminal 2.[4] On July 17, 2010, Skyliner switched its route to the newly built Narita Sky Access and reduced the travel time by 15 minutes.


Keisei operates 152.8 km (94.9 mi) of railway that consists of one trunk line named the Main Line and six branch lines.[1]
