Chuo-ku has been a major transportation hub since the Edo period, and the five highways starting from Nihonbashi extend radially, and there were many banks (Nihonbashi Fish Bank, Daikon River Bank, etc.) as a listing of water transport responsible for logistics in Edo.
Even today, the subway is arranged like a net, and the Metropolitan Expressway, which is responsible for automobile traffic in the Tokyo metropolitan area, has a number of junctions that serve as a junction of traffic.
Among them, I would like to focus on the Hakozaki Junction today.
The Hakozaki Junction is a junction where the No. 6 Mukojima Line diverges from No. 9 Fukagawa Line, but there is a one-way Hakozaki Rotary clockwise in the lower layer.
At the Hakozaki Rotary, the Hakozaki Entrance, the Hamacho Entrance, and the Kiyosubashi Exit Branch are branched and merged, and are connected to both No. 6 Mukojima Line and No. 9 Fukagawa Line. There is a traffic light at the junction of the Hamacho entrance and the rotary, and traffic control is performed. In addition, there is a small but Hakozaki PA at the rotary, and a toilet and vending machine are installed, so you can use it in case of emergency.
The Airport Transport Service limousine bus departs and arrives from Tokyo City Air Terminal (T-CAT) in the center of the rotary, and there is also Suitengu Station on the Hanzomon Line in the basement, making it a truly transportation node.
Why don't you cross Ningyocho, Suitengu, Hamacho Park, Kiyosubashi and go to Kiyosumi Park?
