The third one is Nakasendo on the Gokaido in Chuo-ku. During the Edo period, the road goes north from Nihonbashi through Itabashi-juku and inland. The current part of Chuo-ku overlaps with National Route 6 to the Muromachi 3-chome intersection, but when going north, it is National Route 17 to Imagawa Bridge.
On the narrow road on the east side of National Route 17, one north of Edo-dori St., there is an explanation board (upper left in the photo) of the "Kane Bell Tower Ruins at Kokumachi". There was a bell of time from the early Edo period. Right next to it is also an explanation board for "Night Hantei-Buson Yosa Residence Ruins". Kabumura was a master of the Edoza Shofu school who followed the flow of Basho, Sokaku and Hajin Hayano.
Heading north on National Route 17 and eventually Imagawa Bridge. This is the border between Chuo-ku and Chiyoda-ku, and the Ryuka River used to flow. Imagawa Bridge during the Edo period is known at the beginning of the picture scroll "Kidai Shoran", and the appearance of Setomonoya etc. lined up near the bridge is lively shown. At present, there are stone monuments (upper right in the photo) and explanation boards (lower left in the photo) of the bridge ruins, so you can feel the remnants of the bridge.
The area beyond the guard of JR Kanda Station is 1 km from Nihonbashi (lower right photo). The road from Hongo to Itabashi via Manseibashi is the former Nakasendo, National Route 17. ●Akira Makibuchi
