This is a work depicting the city of Tokyo.
The color scheme and composition are expressed in a refined form that is stripped down to the utmost simplicity, and the design leaves room for interpretation so that the appearance of the city changes depending on the environment in which the work is displayed and the state of mind of the viewer.
When illuminated by the morning sun, the image of the city waking up and starting to move comes to mind, and when illuminated by the night light, the image of the nightscape glowing in orange comes to mind.
The background is not black, but deep gray.
The cityscape is also drawn in light gray, not white, which is a key point.
