Many people know that there is an inconspicuous post near Kyobashi of the "Ginza Birthplace" monument. I think they are taking care of the beauty of the city.
On the east side sidewalk of Chuo-dori, Ginza 2-chome
By the way, in Namiki-dori St., etc., it is an inconspicuous post with dark green. I don't think I've seen it in other parts of Tokyo.
Ginza 5-chome on the east side sidewalk of Namiki-dori St.
On the south side sidewalk of Miyuki Street, Ginza 6-chome
Ginza 7-chome, west sidewalk of Namiki-dori St.
The west sidewalk of Namiki-dori St., Ginza 8-chome
Also, the small post offices in the Ginza area are not on the first floor of a rental building, but on the second floor or above, so this is also a characteristic of the expensive commercial area called Ginza.
