Shot in the city of Shinjuku, Tokyo.
The big wall belonged to a department store was lighted. Under normal conditions, some advertisements were displayed on the wall. Yet nothing was on it at that time. It might be under refit. So the wall was just lighted and in blank.
Many pedestrians were walking in front of the wall because the place was in the downtown. When they passed by the wall, they became silhouetted. And they were profiled by the lighted wall.
