The Rinkai Line (りんかい線, Rinkai-sen) is a railway line located in Tokyo, Japan. It is the only line operated by the third-sector company Tokyo Waterfront Area Rapid Transit. It connects central Tokyo to the artificial islands of Aomi and Odaiba. The line is served by some trains on the East Japan Railway Company (JR East) Saikyō Line which continue on to Shinjuku, Ikebukuro, Ōmiya, and Kawagoe.

Overview

While not part of the Tokyo subway network (as it was built to JR specifications), the Rinkai Line is fully grade separated and runs underground for nearly 10 km of its 12.2 km distance, going as low as 40 meters below the ground when crossing under the Port of Tokyo. The Shinonome – Shin-Kiba segment (which uses the former Keiyō Freight line) is elevated.

History

Construction of the line started in 1992, with the eastern end of the line using the right-of-way of the Keiyō Freight Line (abandoned in 1983).^[6] The first portion of the line between Shin-Kiba and Tokyo Teleport opened for service on March 30, 1996, initially under the name Rinkai Fukutoshin Line (臨海副都心線, Rinkai-fukutoshin-sen). The name was officially changed to the Rinkai Line on September 1, 2000. The extension to Tennōzu Isle opened on March 31, 2001 and the final portion to Osaki on December 1, 2002.

The project ran severely over budget, with an estimated final cost of over ¥440 billion.^[6] In 2005, the Rinkai Line's average ridership was 140,000 passengers per day^[6] and, in 2006, the line finally registered its first operational profit, although interest payments on ¥389 billion yen in debt have resulted in a consistent net loss since 1991. By comparison, the competing elevated Yurikamome line is profitable, thanks to lower construction expenses, higher ticket prices and popularity among tourists and leisure visitors for its scenic views.^[7]

However, the Rinkai Line's ridership has steadily increased since, reaching 200,200 passengers per day in 2010. The ridership is forecast to increase further due to future development planned for the area served by the line.

Tokyo Waterfront Area Rapid Transit, Inc. (東京臨海高速鉄道株式会社, Tōkyō Rinkai Kōsoku Tetsudō Kabushiki-gaisha) was founded on March 12, 1991 for the express purpose of constructing and operating the railway line. It is a third-sector company, and, as of 1 April 2013, 91.32% of shares are held by the Tokyo Metropolitan Government, 2.41% by JR East, 1.77% by Shinagawa Ward, 0.70% by Mizuho Bank, 0.46% by The Bank of Tokyo-Mitsubishi UFJ, 0.34% by Sumitomo Mitsui Banking Corporation, and the remaining 3% by 41 other companies.^[9]

In spite of its severe financial situation, TWR was discovered to have made a five million yen donation to the Tokyo Metropolitan Government on October 16, 2009 to encourage the city's bid for the 2016 Olympic Games.^[10] The company stood to benefit financially if the games were held in Tokyo, as several of the proposed venues were located along the Rinkai Line.

In addition to its ownership and operation of the Rinkai Line, TWR is also involved in real estate and subcontracting/management of station- and building-related design.

Future plans

In August 2014, it was revealed that JR East was in negotiations to buy out the Rinkai Line.^[9] This would make it easier to incorporate the line into its plans for a direct line to Haneda Airport as well as providing through services to and from the Keiyo Line.^[9]
