What is the symbol of Edo?
"Edo Castle" and the castle of Chiyoda may be mentioned first.
There is also a place in Chuo Ward where you can see the vast remain directly.
"Tokiwa Bridge" is built over the outer moat of Edo Castle.
Currently, there are three bridges in this area: Tokiwa Bridge, Former Joban Bridge, and Shin Tokiwa Bridge.
In the middle, the bridge where cars cannot pass is the old Joban Bridge for today's purpose.
The name is a bit confusing, but let's start by looking at the real thing.
Let's get to the ground from the entrance of "B1" at Mitsukoshimae Station on the Hanzomon Line.
(In addition, from Mitsukoshimae Station on the Ginza Line, go straight on Edo Sakura-dori St. while looking at Sumitomo Mitsui Banking Corporation and Bank of Japan head office to the right from the entrance of "A5".)
From there, you can see "Tokiwa Bridge" right away.
Then, follow the road north along the moat, and you will find "Old Jobanbashi".
If you look beyond the bridge behind the Bank of Japan head office, you can see the traces of Masugatamon that remain in the outer moat.
A "U-shaped" masu shape with both wings firmly assembled with stone walls.
In that space, a crown gate, a migratory tower, etc. must have been built.
It's deep. "Omomuki" is not a moat.
This is a large tactic of outer moat that stretches from Edo Castle Ote-mon gate over Uchibori. So to speak, it's the position of the front entrance.
The gate of the border connecting Edo Castle retrenchment and the town.
Along the current Edo-dori St., it was also an important entrance on the Nikko Kaido and Oshu Dochu, leading from Asakusa to Senju-juku, Soka-juku, and Koshigaya-juku.
Is the middle of the bridge the border between Chuo-ku and Chiyoda-ku?
On the other side of the bridge, there is a signboard of "Jobanbashi" of the Chiyoda-ku Board of Education.
"The current Ishibashi is the most valuable Western-style Ishibashi in Tokyo that was rebuilt in 1877 using the stones used for Masugata."
Was stone wall stone used for the bridge?
You can feel the feet you step on.
It is a great view spot for those who have a deep attachment to the castle.
However, it may be a little too deep for those who are concerned about the precautionary notes prohibiting sleeping or eating and drinking in the surrounding area, as well as the feeling of the outer moat water.
Speaking of deep, this area, along the curve between Nihonbashi River and outer moat, the elevated JR line and the elevated Tokyo Metropolitan Expressway cross in a complicated manner, so if you go around Tokiwa Bridge and Shin Tokiwa Bridge, you will lose sight of your position for a moment.
There is "Nihonbashi River Tokiwa Bridge Disaster Prevention Pier" in Horiuchi on the Chuo-ku side (BOJ head office side).
This dock is said to be used as a supplementary facility for land transportation in the event of a disaster such as major earthquake.
The remains of Edo, where rivers and moats were around and boating was developed, were well maintained in places that were difficult to see so that they could function effectively in various situations.
