Keikyu

Keikyu, short for Keihin Kyūkō Electric Railway, is a private railway operator in the Greater Tokyo Area of Japan. The company runs a network centered on the Keikyu Main Line, which connects Shinagawa in Tokyo with Uraga in Yokosuka, Kanagawa, serving major cities such as Yokohama and Yokosuka along the way. A key branch, the Keikyu Airport Line, provides direct access to Haneda Airport, improving airport connectivity for commuters and travelers. The railway network operates a mix of rapid, express, and local services designed to accommodate high passenger volumes and frequent peak-period travel.

In addition to passenger rail services, Keikyu operates associated transportation and real estate activities that leverage its station hubs and surrounding developments. The group is known for its emphasis on punctuality, safety, and customer service, and it maintains arrangements that allow through services with other operators to extend its reach beyond the core line.

Historically, Keikyu traces its roots to late 19th‑ and early 20th‑century private rail ventures in the Tokyo–Yokohama corridor and has undergone several reorganizations and expansions to accommodate urban growth. The name derives from its earlier corporate identity as a private electric railway operator serving the southern Tokyo Bay area.

Keikyu’s operations are centered in Kanagawa Prefecture and the Tokyo metropolitan region, and the company remains a major private rail operator in the area. Its network provides essential commuter routes, airport access, and interchanges that support regional mobility.
