Go along the five highways in Chuo-ku, the second one is Koshu Kaido. During the Edo period, it was on the way from Naito Shinjuku and Hachioji to Shimosuwa via Kofu. The current part of Chuo-ku overlaps National Route 1 and is only a short distance from Nihonbashi. So I would like to go a little further and walk to the junction of National Route 20, which inherits the old Koshu Kaido.
Departing from Nihonbashi, the starting point, walk south on Chuo-dori to Nihonbashi Intersection. So far it is the same as National Route 1, Tokaido, and the current National Route 15. When you turn west at the intersection toward Otemachi, National Route 1 is called Eitai-dori St. (upper left photo). Eventually, we will reach the Gofuku Bridge intersection. It is derived from the fact that there was Gofukumachi in the old days. On the north side, there was "Yumeji Takehisa / Minatoya Esoshi Paper Store" during the Meiji period.
The current Sotobori-dori St., which connects north and south, was built on the ruins of outer moat in Edo Castle, with the Gofuku Bridge on the west side. Take this Sotobori-dori St. toward Kanda to Ichiishibashi. It was the point where outer moat, Dosanbori and Nihonbashi River merged. It is depicted in the 100 views of Edo "Yatsumi no Hashi" and the famous spot event "Hachimibashi". At present, on the west side of Minamizume, there are "Ishiishibashi Lost Stone Marks" during the Ansei period (upper right in the photo) and "Ichiishibashi's main pillar" during the Taisho era, which is a cultural property of the inhabitants of the ward.
Move away from Chuo-ku at the point beyond the Gofuku Bridge intersection and enter Marunouchi, Chiyoda-ku. On the back of the building on the south side is the ruins of magistrate's office Kitamachi (left photo). It can be seen that he ruled Edo City along with the ruins of Minamicho magistrate's office near JR Yurakucho Station. After walking for a while, you will hit the Otemachi intersection. Go straight to Ote-mon gate, and if you go south, National Route 1 will be Hibiya Street.
Walking south along the Uchibori, the Hiroshige Utagawa was born near the Meiji Seimeikan, an important cultural property of Baba Sanmon, near the "Jomon Fire Concentric House". This area was also called "Yatsushirosu Kishi" because of the Jan Jooss Tenyashiki, and in modern times it was Yaesumachi, Kojimachi-ku. Go ahead and you will see Hibiya intersection.
Turn right at the Hibiya Gomon site in Hibiya Park and head west. National Route 1 is Harumi-dori St. and you will reach the Sakuradamon intersection. If you turn left at the south, you will see Sakurada-dori St. on National Route 1 and 3 km from Nihonbashi. If you go straight, you can finally meet Koshu Kaido on National Route 20 (lower right photo). The road from Hanzomon to Shinjuku is now Shinjuku-dori St. ●Akira Makibuchi
