The story will be on October 13, last fall. I had lunch at a Chinese restaurant near Kamejima Bridge (see the previous blog), decided to go a little detour and return to the company, and when I was taking a walk, there was a construction site of the building, so if I looked inside, an old stone wall that could not be underground of the building jumped into my eyes. At that moment, what is this? I thought, and when I looked it up with the old map application, I was just standing in Shinkawa.

What should I do? No one thinks you can see Shinkawa's remain in this place right now. If the construction proceeds, this remains will be buried. I want many people to witness the history of Shinkawa! That's why I decided to contact local media that distributes local news. As a result, Y editor-in-chief of the company immediately visited the site and made an article about the wonderful discovery of remain Shinkawa.

In this way, I was able to witness the history of Shinkawa where I work, and my thoughts and inquisitiveness for Shinkawa grew more and more, which was a great opportunity to take the Chuo-ku Tourism Test.

This blog will follow the traces of Shinkawa, which can be said to be my starting point.

Shinkawa was Zuiken Kawamura (an Australian merchant in the early Edo period) in Manji 3 (1660). Those who have contributed to shipping and flood control. It is said that Higashimiya-mura, Ise-Kunikai-gun) was excavated, and the purpose is to improve the convenience of unloading goods transported from various countries to Edo by boat. As a result of this excavation, Nada and Itami liquor, which are called descending liquors, were transported one after another by barrel boats, and this area became a landing place for sake, and many sake wholesalers gathered.

In Shinkawa, four bridges were already built during the Edo and Kanbun years (1661-1673). However, none of them have a bridge name, and from the upstream, Ichinobashi and Ninobashi. … It was called "Share." After that, one bridge disappeared and it became three, but even after entering the Meiji era, it was called Ichinobashi, Ninobashi, and Sannobashi as before.

Then, in 1923, these bridges were damaged by the Great Kanto Earthquake, and Ichinobashi and Sannobashi were replaced with their original locations as earthquake reconstruction bridges. No name was found, Shinkawabashi was newly built nearby, and Higashishinkawa Bridge was newly established downstream.

However, the Pacific War once again severely damaged the Shinkawa area, and Shinkawa was reclaimed by the scorched earth in 1948-1949, and all four bridges disappeared.

In the Shinkawa area, which has such a history, there are still many sake wholesalers, Masaru Shinkawa Jingu Shrine, which is the guardian angel of sake wholesalers, sake wholesalers, and brewing-related companies.

＞ For more information about the history of Shinkawa, please also see the blog in April (about the town of sake wholesalers "Shinkawa"-Ask President Kashimaya).

Now, let's take a look at the traces of Shinkawa.

First of all, please see [Shinkawa Overall Map] below.

This map uses the Geographical Survey Institute website "Geographical Institute Map / GSI Maps | Geographical Survey Institute", and shows four bridges that span Shinkawa 1-chome from west to east (blue arrow) It is shown.

From now on, I would like to see the traces of each bridge along the path of Shinkawa, which once flowed.

In addition, the name of the bridge from here is "Chuo-ku Cultural Properties Survey Report No. 5 Bridge, Hashizume Plaza-Chuo-ku Modern Bridge Survey-" (Chuo-ku Board of Education, issued on March 2, 1998).

[Overview of Shinkawa]

※ The alphabet (A to H) on the map is the shooting point of the photo posted on this blog (the arrow is the shooting direction).

<Kamejima River junction>

The uppermost part of Shinkawa, which branches off from the Kamejima River, is marked with a round mark (Shinkawa 1-3) in the upper photo below (taken from point A in [Shinkawa overall map]). From here, the Shinkawa flowed east toward the confluence with the Sumida River (flowed left in the photo).

The lower photo (provided by Kyobashi Library in Chuo Ward) was taken in 1948 before Shinkawa was reclaimed, and looked at the Kamejima River from one bridge over Shinkawa. . The building on the front is the "No. 2 Inoue Building" completed in 1927, which is also shown in the photo above.

＞ To the uppermost part (junction with the Kamejima River) where the flow of Shinkawa begins, walk in the direction of Eitai Bridge along Eitai-dori St. from Kayabacho Station on the Tokyo Metro Hibiya Line and Tozai Line, and walk to the Eitai Bridge over the Kamejima River.

<Ichino Bridge>

The first bridge is one bridge.

Ichino Bridge was completed on July 3, 1926, and is a steel girder bridge, a bridge length of 10.3m, and a width of 18.0m. (Completion is not at the time of creation, but at the end It is the bridge that was built (replaced) and the same shall apply hereinafter.) 。

As a result of the earthquake disaster reconstruction project, Hashizume Plaza was set up in three places except for the upper right bank along with the construction of a bridge, but there is no remaining at present.

Then, I would like to take a look at the photos.

The photo below (taken from point B in [Shinkawa Overall Map]) shows the east from the west side of the road that crossed east and west, against a road with a bridge that spanned almost north and south. It was just flowing under this.

The road is an uphill toward the intersection, downhill after the intersection, and it is a terrain that once shows that there was a bridge there and a river (if you reclaim the bridge and river, usually the bridge The place where the bridge was located is the highest and the surrounding area is lower.) 。

However, I think that this height difference is difficult to understand in a flat photo, so I tried to make a cross-section using the tool on the Geographical Institute map earlier.

The section below is the cross section, and the road that crosses east and west is cut vertically to the road where one bridge was located, and viewed from the side (from south to north). You can see that the place where the bridge was located (where it is + in the cross section, 3.49m above sea level) is the highest.

The following photo (taken from point C in [Shinkawa overall map]) is a road that runs north and south through the place where one bridge was located. This road is also slowly lowering north and south at the place where the bridge was located.

After all, I think it's hard to understand in the photos, so I also tried to make a cross-section using the tool of the Geographical Institute map.

This cross-sectional view is a vertical cut out of the road running north-south from the other side of the photo (connected to Hakozaki Minatobashi Street when going north) and viewed from the side (east to west). After all, you can see that the place where the bridge was located (where it is + in the cross section, 3.49m above sea level) is the highest.

The roads that can be seen slightly on the left and right of the photo are the roads that cross east and west against the roads that had this one bridge, as seen earlier, and go downhill at the intersection.

<Shinkawabashi>

The next bridge is Shinkawabashi.

Actually, at the beginning, we were preparing for the two bridges, but as we examined the literature, as mentioned above, the two bridges were damaged by the Great Kanto Earthquake and were not rebuilt afterwards. I knew that it was bridged as Shinkawabashi, so it was explained by Shinkawabashi.

Shinkawabashi was completed on February 15, 1930, and is a steel girder bridge, a bridge length of 16.0m, and a width of 15.0m, as well as one bridge.

Hashizume Plaza was set up in four places along with the construction of a bridge due to the earthquake reconstruction project, but there is still no remaining at present.

Then, I would like to take a look at the photos.

First of all, the upper left of the photo below (taken from point D in [Shinkawa overall map]) was taken toward the place where Shinkawa was flowing (east side) where Shinkawabashi was located. It is a place where you can imagine Shinkawa, which was flowing gently curving to the left.

The photo in the upper right (taken from point E in [Shinkawa overall map]) was taken from the east side of the place where Shinkawabashi was located, and the construction site visible beyond the intersection is like. It is the place where remain in Shinkawa was located. The photo at the bottom left shows Shinkawa's remain. You can also see something like a drain of the sewer. Construction is progressing at the current construction site, and unfortunately we cannot see this remain.

The last photo (provided by Kyobashi Library in Chuo Ward) was taken in 1948 (1948) and saw Shinkawabashi from Higashishinkawa Bridge. It will be taken from the same direction as the photo in the upper right corner.

<Higashishinkawa Bridge>

Next to Shinkawabashi is Higashishinkawabashi.

Higashishinkawa Bridge was completed on August 1, 1928, and a new arterial road (Kajibashi Dori) that divides the Shinkawa area diagonally by land readjustment after the Great Kanto Earthquake was newly established, along with Shinkawa It was built. The format is a concrete arch bridge, an earthquake reconstruction bridge with a bridge length of 18.5m and a width of 22.0m.

As a result of the earthquake disaster reconstruction project, Hashizume Plaza has been set up in four places along with the construction of a bridge, and now it remains with its name only on the upstream side of the left bank as "Higashishinkawa Bridge Public Toilet".

Then, I would like to take a look at the photos.

The left photo below (taken from point F in [Shinkawa overall map]) shows the place where Higashishinkawa Bridge was located from the place where Shinkawabashi was located. As you can see in the cross-sectional view of the Geographical Institute map, this is a place with fine undulations, once going down to the east, and then going uphill.

The photo at the lower right (provided by Kyobashi Library in Chuo Ward) is Higashishinkawa Bridge taken in 1930 (1930), and seems to have been taken from the east side of Higashishinkawa Bridge.

The following photo (taken from point G in [Shinkawa Overall Map]) shows a photo seen from the east side of Kajibashi Street where Higashishinkawa Bridge was located, and the section of the Geographical Institute map is sloped to the right (north side). I think you can understand with the view. In addition, it goes uphill from the road in front to Kajibashi Street where there was a bridge, and goes downhill after passing the street.

<Three Bridges>

The last bridge is three bridges.

The Sanno Bridge was completed on February 25, 1926, and is a concrete girder bridge, a bridge length of 13.5m, and a width of 8.0m.

As a result of the earthquake disaster reconstruction project, Hashizume Plaza has been installed at three locations except on the lower right bank along with the construction of a bridge, and currently remains as part of Shinkawa Park only on the lower left bank.

Then, I would like to take a look at the photos.

The photo below (taken from point H in [Shinkawa Overall Map]) shows the location where the three bridges were located from the north side. You can see that this road is also uphill toward the place where the bridge was located, along with the cross-sectional view of the Geographical Institute map. However, since this point has the Sumida River on the east side and the uphill towards Super dike, it is unlikely to be a trace of three bridges.

<Confluence of Sumida River>

I found a sign (upper left in the photo below) of "Tokyo Metropolitan Sewerage Bureau storm surge tide gate" (*) on the wire mesh (backwards Sumida River) on the eastmost east side of Shinkawa Park. The fact that there is a storm surge tide gate here means that there is a facility that discharges rainwater etc. to the Sumida River under this, and on the revetment (hereinafter referred to as the "terrace") maintained as the Sumida River Terrace (hereinafter referred to as the "terrace") There is a white guardrail in the bush just below the place where the signboard was located, and the Sumida River is at the end of the 3m border. Well, what does this mean?…。

So I contacted the manager, Chubu Sewerage Office, which was written on the signboard, and said that this door was not on the office's jurisdiction list and was not used now . In that case, is the dent at the end of the terrace blocked the vomit that used to release rainwater, etc.?…。

There was a photo at the time of 1949 when Shinkawa was reclaimed (a photo in the lower center, a photo of the three bridges from Higashishinkawa Bridge, provided by the Kyobashi Library in Chuo Ward). I found that a sewer pipe was laid just under this sign.

From the above, I think there is no doubt that this was the junction with the Sumida River in Shinkawa (pictured at the lower right).

（＊） The Chuo-ku Regional Disaster Prevention Plan (revised in 2021) Chuo-ku Disaster Prevention Council states that the Sumida River storm surge embankment (right) and the tide gate at the sewer outlet at the Nihonbashi River storm surge embankment will prevent water disasters caused by storm surges and reduce damage. It is installed for the purpose of reducing it. "

Following the traces of Shinkawa, I walked along the road reclaimed Shinkawa, but the road curved slightly, there were undulations in the place where the bridge was located, and I understood the traces of reclaiming the river again .

Chuo-ku used to have many rivers and canals, but now most of them have been reclaimed and have turned into roads and parks. However, it is very fun to visit such places and walk while thinking of old sights. Maybe you will encounter the river remain at the construction site.

Why don't you walk along the ruins of Shinkawa and imagine the bustling Shinkawa riverbank with young sake arriving from above?
