At the foot of the bridge, there is a square of the original mark, which has a copy of the Japanese road mark and a Tokyo road mark. There are also two milestones that represent the distance to various parts of Japan. Surprisingly unknown, the actual Japanese road mark is located in the center of the bridge. At present, road signs have no legal meaning, but all Japanese roads begin in Nihonbashi. Ieyasu Tokugawa connects Edo and various places, but began to improve the highway, and during the Hidetada era, a main road was established, and the maintenance was promoted under the control of Michinaka magistrate.

If you walk in the direction of Ginza from Nihonbashi, the old Tokaido and the old Koshu Kaido will begin. The Tokaido goes to Sanjo Ohashi in Kyoto. Koshu Kaido takes about 220 kilometers to Shimosuwa, where it joins Nakasendo. If you walk in the direction of Kanda, the old Nakasendo, the old Nikko Highway, and the old Oshu Highway will begin. Nakasendo is about 510 kilometers away and passes through inland areas such as Shinshu and Mino, and joins the Tokaido at Kusatsu-juku in Oomi. Nikko Kaido is about 130 kilometers long and runs to Shinkyo bridge at Nikko Toshogu Shrine. Nikko Kaido branches off from the Oshu Kaido in Uto Miyajuku. The Oshu Kaido is a highway that was under the jurisdiction of Michinaka magistrate until Shirakawa-juku (Muku Shirakawa). From Shirakawa-juku to Sanmaya-juku on the Tsugaru Peninsula, it is called Sendai Road, Morioka Road, Matsumae Kaido, etc., but is generally referred to as Oshu Kaido. The distance is about 800 kilometers.

Even today, many people called highway walkers start from Nihonbashi or walk along Gokaido as a hobby with Nihonbashi as their destination. At the end of the highway walker, the owner of Ashuan, started walking on the highway from over 60 years old, and started walking from Nihonbashi and finished all of the five highways. Here's a photo of the end of each highway that you started walking from Nihonbashi.
