Keisei Electric Railway

Keisei Electric Railway operates trains and buses in Tokyo and Chiba. It's main line serves eastern Tokyo and several Chiba suburbs including Ichikawa and Funabashi and ends at Narita Airport. It's second most used line runs within Chiba. It also operates a variety of short lines. It uses standard gauge trains which distinguishes it from JR.

The Keisei group includes multiple subsidiaries that serve Ibaraki as well as Chiba and Tokyo. For the most part there is a subsidiary for each line. However, the Kanto Railway runs two lines and buses between Tokyo and Ibaraki while the Tsukuba Tsukuba Kanko Railway operates a cable car, a ropeway, hotels and restaurants on Mount Tsukuba. Subsidiary lines usually use old (diesel) or very new technology. Keisei will be the main operator of the Narita New Rapid Line which will have a top speed of 160km/h. That will make it the fastest third sector railway in the Tokyo area.

It also has extensive real estate holdings. Through its majority share in the Oriental Land Company, it manages Tokyo Disneyland, and it runs the Maihama Resort Line which serves the resort area.
