The place name "Ginza" has expanded the area with several changes in address notation, but it shows the presence of Chuo-ku, or as the main street in Japan.
As you walk along Ginza Street to find out where the southern end of Ginza is located, you will pass through the guard of the expressway in front of Shimbashi Station and enter Minato-ku. This is the border, isn't it?
It seems that the Shiodome River once flowed here, and a bridge called "Tsuchihashi" was hung. A remnants are left at the entrance of the expressway called "Tsuchihashi Lamp". (The photo shows the direction of Ginza from the Minato-ku side.)
Let's enjoy "Gin Bra" today while surviving the former water town of Chuo-ku surrounded by rivers.
