Due to many rivers and diggings, the current Chuo-ku has been called the "city of water" since the Edo period.
However, over the years, rivers have been reclaimed, and their remnants can be known from the information boards and the remaining main pillars.
When and what was landfilled, and how the town changed?...
If you remember such things like 5W1H, you can connect events with each other in a causal relationship.
The history of the development of Chuo-ku will be easier to come to mind.

The events that triggered river reclamation can be broadly divided into the following four categories.
Earthquake reconstruction, war reconstruction, Tokyo Olympics, etc.

■Earthquake reconstruction
The Irifune River, the Tepposu River, and the Nishibori Ru River (Isecho Hori) were reclaimed at this early stage.

■Reconstruction of war
At that time, there were no vehicles or fuels carrying surplus soil or debris.
Therefore, rivers that are not very necessary as waterways are reclaimed with residual soil and debris to create land and create land.
The Tokyo Metropolitan Government's debris disposal measures were implemented to sell it and generate operating costs.
That was the landfill, and the northern half of the outer moat River and the Sanjuken River disappeared at this time.

■Tokyo Olympics (1964, 18th)
In preparation for the Olympics, highways, subways, and arterial roads were urgently developed.
Therefore, the Tsukiji River and Kaede River were reclaimed, and the capital height centered on Route 1 (4.5 km between Kyobashi and Shibaura) was constructed, and the Tsukuda River was reclaimed by the bridge of Tsukuda-ohashi Bridge (1964). Was.
However, because it was reclaimed too quickly, it was impossible to drain rainwater.
Therefore, pumping stations of the Tokyo Metropolitan Sewerage Bureau were set up in Hamacho, Nakasu, and Hakozaki-cho.

<Aside>
The torch relay course is 1.5km between Kiyosu Bridge and Kayaba Bridge.
It was 2.0 km between Kayababashi and Kajibashi.

You don't have to remember in particular about river reclamation, but you don't have to worry about it.
If you know it, you will surely enjoy walking around the town.
