Since the reclaimed alley of the Ryuka River is the ward boundary between Chiyoda-ku and Chuo-ku, this time we will walk along the Sotobori-dori St. from the estuary where the Ryuka River connects to Nihonbashi.
There is no road along the Nihonbashi River to Tokiwa Bridge, even though it is not well-maintained along the river, so you will walk along Sotobori-dori St.
After Tokiwa Bridge, the Nihonbashi River turns greatly to the left, and the ward border with Chiyoda-ku crosses Ichiishi Bridge to become the former Soto Horikawa.
Originally, it is natural to have Chiyoda-ku on the west side of Sotobori-dori St. and Chuo-ku on the east side. However, the outer moat River used to be located on the west side of Sotobori-dori St., along the Sotobori-dori St., and since the center line is the ward, a part of the west side of Sotobori-dori St. (part facing Sotobori-dori St.) is in Chuo-ku.
In fact, at the Daiichi No. 2 Steel Building (currently under construction) to the north of Tokyo Station, the ward world passes through the building, and it seems that Yaesu 1-chome 10th and 11th blocks are set.
The address of the steel building is Marunouchi, Chiyoda-ku, but strictly speaking, the entrance along Sotobori-dori St. is Haz in Chuo-ku.
There are several buildings built on the reclaimed land of the outer moat River from Ichiishibashi to Kajibashi, but there is no indication of the address of the building at all along Sotobori-dori St. Is there any hesitation or hesitation in displaying this as Marunouchi, Chiyoda-ku in the part of Chuo-ku?

This can be seen by passing the blacksmith bridge and eventually the highway appears on the ground.
The "Tokyo Kosoku Doro" building is built on the reclaimed Soto Horikawa, where the top is used as a road and the bottom is used for shopping, and the road is hidden underground from the Kaji Bridge and invisible.
In other words, the buildings with shopping malls such as "GINZA INZ 123", "NISI GINZA" and "GINZA 5" were built on the ward of Soto Horikawa, and are now an extra area without an address.
However, there is no resident registration in this area and there is no problem such as resident tax paid to the ward, and there is no problem even if you do not specify an address because it is only a business establishment.
By the way, the fire department and the police have jurisdiction for each commercial facility. In the case of "NISHI GINZA", the fire department is Marunouchi, Chiyoda-ku, and the police are under the jurisdiction of Tsukiji, Chuo-ku.
In addition, mail arrives at the convenience address "4-1 Ginza, Chuo-ku" for postal mail.
"GINZA INZ" is "2-2 Ginza west, Chuo-ku" (currently there is no indication of Ginza west.)
"GINZA 9" is "8-10 Ginza, Chuo-ku", and Ginza may be attractive even though it is a convenience address.
In the past, "GINZA INZ" was a restaurant and food sales area under the name of "Yuraku Food Center", but at this time Frank Nagai's "Let's meet in Yurakucho" became a big hit, so at that time, Yurakucho had more brand power than Ginza?
"NISHI GINZA", famous for the Treasure Lottery Chance Center, deals with the latest trend of clothing under the name "Nishiginza Department", and "GINZA5" deals with items such as fashionable accessories under the name "Sukiyabashi Shopping Center", and these shopping malls were such a kind of thing that could be said to be pioneer in Japan.
Since these shopping malls are located on the reclaimed land of the outer moat River, will the ward boundaries between Chuo-ku and Chiyoda-ku be the center passage of these malls? 
After passing through "GINZA5" and crossing Miyuki Street, the shopping mall ends and becomes "Ginza Corridor Street" lined with restaurants.
Eventually, at the police box in Tsuchihashi, the expressway turns to the left and becomes "GINZA9".
In the past, Soto Horikawa became the Shiodome River and was reclaimed, and "GINZA9" became the ward boundary with Minato-ku.
"Ginza 9-chome Mizukami" sung by a singer named Ichiro Kanbe in the 1980s became a big hit, but "GINZA9" was not given from there, and was initially named "Shimbashi Center". After all, it was attached because Shimbashi Station is close.
In fact, it seems that there were many small izakayas that served as hangouts for office workers in Shimbashi.
At present, there are many shops dealing with dresses of luxury bar moms and hostess in Ginza.
"GINZA9" also ends on Showa-dori, and the elevated capital city that passes through Kaigan-dori and above becomes a ward border with Minato-ku along the Hamarikyu Garden, and from Shiodome River to Tokyo Bay, Harumi Canal from Harumi Wharf to Toyosu, Koto-ku It becomes the ward boundary with. 。
