The Tokyo Metropolitan Government has announced plans to construct two new metro lines in line with the city’s development after the 2020 Summer Olympics.
One of the proposed new lines will connect Tokyo Station to the Rinkai waterfront area, and include Ginza, Harumi and Ariake. The other line will connect Shinagawa, a starting station for the Linear Chuo Shinkansen which is scheduled to open in 2027, and central Tokyo. The existing Tokyo Metro Nanboku Line may be extended from Shirokane-Takanawa Station.
The metropolitan government will ask the Transport Ministry’s policy council to include the two new lines in its national policy on rail expansion. The total estimated cost for the new railway project is 320 billion yen (USD 2.6 billion). Layout design and logistics planning are expected to take three years, and construction is estimated to take about 7 years.
JR East has already announced plans to build three new train lines linking Haneda airport to stations at Tokyo, Shinjuku and Shin-kiba. The new lines will cut the travel time from Tokyo station to Haneda to just 18 minutes, from 28 minutes, and from Shinjuku to Haneda to 23 minutes, from the current 41 minutes.
