Nijubashi Bridge

Two bridges run from the front square, through the main gate and over the moat leading to the Imperial Palace. The bridge closer to the National Garden is Seimon Ishibashi; the one further is Seimon Tetsubashi. The two bridges are collectively called Nijubashi. The bridge is so called because the previous bridge, made of wood, required a supporting platform in the middle, creating a two-tiered structure. The present bridge, made of steel, was built in 1964. Although crossing the bridge is part of the Imperial Palace tour, in actual fact Nijubashi is only used for certain official events such as visits by foreign dignitaries. Join the free Imperial Palace tour at Kikyo-mon Gate, a 3-minute walk from Exit 6 of Nijubashi-mae Station on the Tokyo Metro Chiyoda Line, or from Exit D2 of Otemachi Station on the Toei Mita Line.
