The answer is "Gyotoku" nightlight park
(I'm sorry not Chuo-ku.)

In the Edo period, Gyotoku was salt.
It is said to have a history of more than a thousand years, and in the early Edo period, it was heavily protected by the general.

I knew it as a knowledge, but
I didn't know there was a nightlight engraved with "Nihonbashi".

Below are some excerpts from the Ichikawa City official website.

It was in 1632 (1632) that the operation of ships traveling between Edo and Gyotoku began. Hon Gyokutoku Village, which had the exclusive right to the route, set up a riverbank here, and the ship operated daily from 6:00 am (6:00 am) to 6:00 pm. This ship was generally called "Gyoto Kubune", which went down the Edogawa River, sailed about 12.6 km to Nihonbashikoamicho via the Shinkawa and Onagi Rivers. The area around the current nightlight is called Shingashi, and according to "Katsushika Magazine", it is presumed that the landscape was maintained in 1690 (1690).
　Eventually, during the cultural and Bunsei period (1804-1830), travelers used more as a pilgrimage route to Mt. Narita, and the number of Gyotoku ships, which was initially 10, increased to 62 during the late Tokugawa shogunate period, and traffic with Edo became more and more active.

The nightlight, the first Tangible Cultural Property designated by Ichikawa City, was built in 1812 (1812) by people visiting the banks of Edo Nipponbashinishi and Naritasan in Kurayashiki to pray for the safety of the route.

There are a lot of highlights.
From Nihonbashi to Gyotoku, it would be fun to think about the people who came and went by boat at that time.
