Keiyō Line

Keiyo and Sotobo Line trains at Soga Station

The Keiyō Line (京葉線, Keiyō-sen^?) is a 43 km narrow gauge (1067 mm) railway line connecting Tokyo and Chiba, Japan, running mainly along the edge of Tokyo Bay. It is operated by the East Japan Railway Company (JR East).

The line was partially opened in 1986 and was completed in 1990. It is the main rail access to the Tokyo Disney Resort and the Makuhari Messe exhibition center.

The terminus at Tokyo Station is located underground, some distance to the south of the main station complex about half way to Yurakuchō Station. This means transfer between other lines at Tokyo Station can take between 15 and 20 minutes. The platforms at Tokyo Station were originally built to accommodate the Narita Shinkansen, a planned (but never built) high-speed rail line between Tokyo and Narita International Airport.

The name Keiyō is derived from the second characters of the names of the cities linked by the line, Tōkyō (東京) and Chiba (千葉). It is occasionally confused with the Keiō Line, a different railway line in western Tokyo.
