One of Tokyo’s most important historical structures, and the starting point from which all roads were measured when Tokugawa Ieyasu undertook the construction of the five routes. The zero point marker is a metal plate located in the middle of the bridge (on the road). Unfortunately, the highway running overhead somewhat detracts from Nihombashi’s historical significance; although there are voices calling for the road to be re-routed ahead of the Tokyo 2020 Summer Olympics.
