The {{nihongo|'''Rinkai Line'''|りんかい線|Rinkai-sen|lead=yes}} is a railway line in [[Tokyo]], Japan. It is the only line operated by the [[Public-Private Partnerships In Japan|third-sector]] company [[#Operating company|Tokyo Waterfront Area Rapid Transit]]. It connects central Tokyo to the [[artificial island]]s 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 {{STN|Shinjuku|x}}, {{STN|Ikebukuro|x}}, {{STN|Ōmiya|x|Saitama}}, and {{STN|Kawagoe|x}}.

==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 {{Cvt|10|km}} of its {{Cvt|12.2|km}} distance, going as low as {{Convert|40|m|sp=us}} below the ground when crossing under the [[Port of Tokyo]]. The Shinonome &ndash; Shin-Kiba segment (which uses the former Keiyō Freight Line) is elevated.

== Station list ==
All stations are located in [[Tokyo]]. All trains stop at every station on the line.

==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).<ref name="jrtr">[http://jrtr.net/jrtr42/pdf/f38_end.pdf JRTR 38: Rapid Transit and Related Urban Development in Tokyo Waterfront Area]</ref> The first portion of the line between {{STN|Shin-Kiba|x}} and {{STN|Tokyo Teleport|x}} opened for service on March 30, 1996, initially under the name {{nihongo|'''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.<ref name=":0">{{Cite web |title=企業情報 |trans-title=Company Information |url=https://www.twr.co.jp/enterprise/tabid/201/Default.aspx |archive-url=https://web.archive.org/web/20231130043850/https://www.twr.co.jp/enterprise/tabid/201/Default.aspx |archive-date=30 November 2023 |access-date=30 January 2024 |website=twr.co.jp |language=ja}}</ref> The extension to {{STN|Tennōzu Isle|x}} opened on March 31, 2001,<ref name=":0" /> and the final portion to Osaki on December 1, 2002.<ref name=":0" />

The project ran severely over budget, with an estimated final cost of over ¥440 billion.<ref name="jrtr"/> In 2005, the Rinkai Line's average ridership was 140,000 passengers per day<ref name="jrtr"/> 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.<ref name="jrtr16">[http://jrtr.net/jrtr16/pdf/f15_iwata.pdf JRTR 16: Tokyo’s New Waterfront Transit System]</ref>

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.

Station numbering was introduced to all Rinkai Line stations in 2016.<ref>{{Cite web |date=22 March 2016 |title=りんかい線「駅ナンバリング」の導入について |trans-title=Introduction of Rinkai Line "Station Numbering" |url=https://www.twr.co.jp/tabid/101/ItemId/218/dispmid/860/Default.aspx |archive-url=https://web.archive.org/web/20230109050253/https://www.twr.co.jp/tabid/101/ItemId/218/dispmid/860/Default.aspx |archive-date=9 January 2023 |access-date=9 January 2023 |website=twr.co.jp |language=ja}}</ref>

{{Nihongo foot|'''Tokyo Waterfront Area Rapid Transit, Inc.'''|東京臨海高速鉄道株式会社|Tōkyō Rinkai Kōsoku Tetsudō Kabushiki-gaisha|lead=yes|group=lower-alpha}} was founded on March 12, 1991, for the express purpose of constructing and operating the railway line. 

It is a [[Public-Private Partnerships In Japan|third-sector]] company, and, as of 1 April 2014, 91.32% of shares are held by the Tokyo Metropolitan Government, 2.41% by [[JR East]], 1.77% by [[Shinagawa, Tokyo|Shinagawa Ward]], 0.7% by [[Mizuho Bank]], 0.46% by [[MUFG Bank]], 0.34% by [[Sumitomo Mitsui Banking Corporation]], and the remaining 3% by 41 other companies.<ref name="yahoo20140822">{{cite web|url= http://headlines.yahoo.co.jp/hl?a=20140822-00010002-norimono-ind|script-title= ja: JR東日本のりんかい線買収でどう変わる？|trans-title= What will change if JR East buys out the Rinkai Line?|date= 22 August 2014|location= Japan|language= ja|archive-url= https://web.archive.org/web/20140829065210/http://headlines.yahoo.co.jp/hl?a=20140822-00010002-norimono-ind|archive-date= 2014-08-29|access-date= 30 August 2014|url-status= dead}}</ref>

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 [[Tokyo bid for the 2016 Summer Olympics|bid for the 2016 Olympic Games]].<ref>報道特集NEXT, Tokyo Broadcasting System. November 7, 2009.</ref> 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==
{{See also|Haneda Airport Access Line Plan}}
In August 2014, it was revealed that JR East was in negotiations to buy out the Rinkai Line.<ref name="yahoo20140822"/> 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 JR  [[Keiyo Line]].<ref name="yahoo20140822"/>
