Eitai Bridge

Eitaibashi Bridge was the fourth bridge built on the Sumida River and was completed in August 1698.

History of Eitai Bridge

Eitaibashi Bridge was built to connect Fukagawa and Nihonbashi bridges using timber from the main hall of Kan-eiji Temple in Ueno. It was built to celebrate the 50th birthday of Tsunayoshi Tokugawa, the fifth shogun of the Edo shogunate. It is said that the bridge was built 100 meters upstream from the present location.
There are two theories about the origin of the name Eitai Bridge.
One is that the area around Saga-cho was called “Eitai-jima” at that time.
The other is that it was built to ensure that the Tokugawa Shogunate would continue in power for many generations to come.

It is said that the Edo Shogunate started to charge a toll when the kitchen situation of the Edo Shogunate became difficult, and it was a toll bridge. On August 19, 1807, the Eitaibashi Bridge could not bear the weight of the many people who came to celebrate the Fukagawa Tomioka Hachiman Shrine Festival, and there was an accident in which the bridge collapsed.

Eitaibashi Bridge was rebuilt and used until Meiji era. Eitaibashi Bridge was replaced by an iron bridge in 1897, but it was damaged again by the Great Kanto Earthquake, and became the present bridge in 1926 as the first earthquake reconstruction project.

Central Bridge

Chuo Ohashi Bridge is a bridge that didn’t exist when fishermen from Settsu, who were called by Tokugawa Ieyasu, moved to Tsukuda Island, and a new bridge was completed in March 1993
Tsukudo-jima is a natural sandbank that was created at the mouth of the Sumida River, and at that time, people used to use ferry boats to get to the island. One of them is the Tsukudo-jima ferry monument.

The Chuo Ohashi Bridge is a cable-stayed bridge with a structure in which cables stretched diagonally from the towers are directly connected to the bridge girders.
When you look at it closely, you will be overwhelmed by the thick wire cables that are stretched in a straight and powerful line.
The bridge girders of the Chuo Bridge were manufactured at the Yokohama factory of Ishikawajima Harima Heavy Industries, which is closely related to Tsukuda Island (Ishikawajima).

The Sumida River has a friendship river partnership with the Seine River in France, and the Chuo Ohashi Bridge was designed by a French design company.

tukuda-0014This “Messenger” was presented to Tokyo by Jacques Chirac, then mayor of Paris, as a token of friendship.
The Messenger faces the river, so it is difficult to photograph his face.

tukuda-0016The Messenger was exhibited at the Paris Exposition, and the cast piece was later presented by Jacques Chirac, the mayor of Paris at the time, and installed on the Central Bridge.


Aioi Bridge

tukuda-aioi-01Aioi Bridge is a bridge on Harumi Canal (Sumida River) and Kiyosumi Street.

Aioi Bridge was built in March 1903. Until then, the only way to get to Tsukudukushima or Tsukishima was by ferry, as you can see on the Tsukudukushima ferry monument. The Aioi-bashi Bridge was also used for the purpose of passing the waterway to the Tsukishima side.
At the time, the Aioi Bridge consisted of two bridges across what is now Nakanoshima Park. They were “Aioi Ohashi” (147 meters) and “Aioi Kobashi” (53 meters).
However, two months later, on September 1, the Great Kanto Earthquake hit the Aioi Bridge, and the Aioi Bridge was destroyed by fire.
This accident made Tsukishima an isolated island again, but the bridge was rebuilt in 1926 as part of the earthquake reconstruction project.
The bridge was rebuilt in 1926 as part of the earthquake reconstruction project, and was later reconstructed in December 1998 due to increased traffic.

Origin of the name of Aioi Bridge

Aioi means that two or more trees grow out of the same root, and the Aioi pine tree is a pine tree with a black pine and a red pine growing out of one root.
The Aioi Bridge consists of the Aioi Ohashi Bridge and the Aioi Kobashi Bridge across the island in the middle, and it is said that it was named Aioi Bridge because it is Aioi because there are these two bridges.

There is another origin “the bridge relative to Eitaibashi upstream”. This is written on the information board of the Aioi Bridge of the Tokyo Metropolitan Government Bureau of Construction, so it is a strong basis, but I would like to support “Aioi because there are two bridges” rather than “Aioi Bridge” from “relative to Eitaibashi”. Well, it must have been named with various meanings.

Contents of the guide board of Aioi-bashi bridge
Aioi Bridge spans the Sumida River Hawa River and was named as a bridge relative to the Eitai Bridge upstream.
The form of the bridge is a truss bridge, following the form of the previous bridge which was reconstructed in 1919 to carry streetcars.
A truss bridge is a bridge with bridge girders made of long, thin members assembled in a triangular shape.
The new Aioi Bridge is designed to be a place of recreation and relaxation for many people, along with the Sumida River and Nakanoshima Park.
The bridge is 149.1 m long and 36.8 m wide.
The bridge was opened to traffic on December 1 and 9, 1998. The bridge was opened to traffic on December 1, 1998.

Aioi Bridge Monument


When Tsukudukushima was reclaimed and turned into Tsukishima, it became a town where people lived, and transportation and water supply became necessary.
The Aioi Bridge was built between Tsukushima and Fukagawa. This was in 1903.
Later, the bridge was repaired and divided into two bridges at Nakanoshima Island. The Sumida River bends at the left side of the bridge, where the river branches off to the left and right, and the water from the upper reaches of the river is held there. At the time of the Great Kanto Earthquake and after the air raids of the World War II, various things were gathered here like a mountain.
In addition, because the bridge was a wooden bridge until the time of the earthquake, the fire spread to the bridge as well. The present bridge was completed in November 1926 as the first bridge The present bridge was completed in November 1926 as the first bridge for the earthquake reconstruction project.


Tsukuda Bridge

The Tsukuda Bridge was completed in 1964 and was built over the Tsukuda Ferry, which had been used as a ferry for 320 years.
The Tokyo Olympics were held in 1964, so naturally, this bridge was built with the Tokyo Olympics in mind.

There was a Tsukuda river between Tsukuda island and Tsukishima that separated them. During this construction, the Tsukuda island was reclaimed for the construction of the attachment road for the Tsukuda Ohashi bridge, and the Tsukuda island that was an island became landlocked, and at the same time the Tsukuda bridge that spanned the Tsukuda river was abandoned.

tukuda-tukudaoohashi-01The bridge girder of the Tsukuda Ohashi is the Tsukudukushima factory of Ishikawajima Harima Heavy Industries (now IHI), though it is not there now.
The Tsukudukushima factory and the Tsukuda Ohashi bridge were close to each other.

tukuda-tukudaoohashi-02Construction of the Tsukuda Bridge began in December 1961 and was completed on August 27, 1964.

Tsukuda River tributary

Tsukudagawa branch river (Tsukudagawa shisen) is a branch river of the Tsukuda river that was reclaimed for the construction of the Tsukuda Ohashi bridge attachment road.
The Tsukuda River branch river is where the Tsukuda Island Fishermen’s Cooperative Association and other fishermen’s boats dock. So there are fishermen in Tokyo.
Fishermen! Hang in there!

There is a signboard of Tsukuda Sumiyoshiko (Tsukuda Sumiyoshi Ko) which consists of only boys. Tsukuda Sumiyoshiko is a voluntary organization that manages the festivals and various events of Sumiyoshi Shrine

tukuda-tukudaoohashi-11Sumiyoshi Sluice Gate is a sluice gate between the Sumida River and a branch of the Tsukuda River.

tukuda-tukudaoohashi-12Sumiyoshi Kobashi Bridge spans a branch of the Tsukuda River.
The sphere on the red main pillar is called giboshu (擬宝珠), which is an ornament attached to the parapet of bridges, temples and shrines.
Giboshu is also called “Negidai (green onion stand)” because it looks like a green onion flower.
