The Tokyo Rinkai Subway Line (東京臨海地下鉄線) is the tentative name for a planned underground heavy rail line which will run north-south between Tokyo Station and the Ariake district along Tokyo Bay. As of 25 November 2022, the projected completion date is in the 2040s.




Background


Plans to construct a new subway line connecting Tokyo Station to the Tokyo Bay area had been in discussion since 2015 as Tokyo was undergoing preparations to host the 2020 Summer Olympics. However, on 25 November 2022, Tokyo governor Yuriko Koike revealed concrete plans to construct the subway line. The line will be around 6.1 km (3.8 mi) long and will feature 7 stations. Overall, the cost is expected to be ¥420−510 billion and is projected to open in the 2040s. There are plans to run through services with the Rinkai Line and the Tsukuba Express along with a possible integration with the JR Haneda Airport Access Line. There are also plans to have a spur connection to the Toyozumi Line at Toyosu Station. The rationale for building the line is due to the development of Tokyo Bay and the integration of leftover facilities from the 2020 Summer Olympics such as the athlete's village (which have since been remarketed as condominiums) and competitor venues. In addition, the island on which the former athlete's village is located, Harumi, remains without a railway connection.
Construction is projected to begin in the 2030s. As of November 2022, the company in charge of construction has not been decided.
