By 2040, Tokyo is going to have a new metro line.
Expected to cost between ¥420 and ¥510 billion (at today’s unpredictable exchange rate, that’s around US$3.18 billion to US$3.67 billion), the new line, which aims to connect Tokyo Station with Ariake — home of Tokyo Big Sight (one of the largest convention centers in Japan) in the Tokyo Bay area — will see at least seven stations built.
Per the map above, the stations will be: Tokyo Station, New Ginza, New Tsukiji, Kachidoki, Harumi, Toyosu Market (the sterile place that took over tuna auction duty from Tsukiji Market), and Ariake/Tokyo Big Sight. These are just placeholder names for now, but given the city’s penchant for actually useful station names, they may be correctly titled after all is said and done.
The Tokyo Bay/waterfront area by Ariake and Toyosu has seen a giant increase in construction cranes for new apartment buildings since a few years before the Olympics. With the new growth in the area, as well as near the old location of Tsukiji Wholesale Market, city planners and Tokyo Governor Yuriko Koike made the thrilling statement late last year.
And in more metro system news coming from Japan’s capital, it has been announced that Tokyo Metro’s Yurakucho line will be elongated to reach the eastern Koto ward (江東区) of Tokyo. With an estimated completion date of the middle of 2030, the extension will be calling at Toyosu, Koto Ward Office, and Sumiyoshi.
