In the real world, Tokyo (東京 Toukyou) is the capital of Japan. In Touhou Project, Tokyo is only referenced in Retrospective 53 minutes where it is revealed that it is no longer the capital of Japan after it was moved to Kyoto in the "Jinki" era.
This Tokyo seems to have a rather poor perception. It is described as rural, due to having things such as amusement parks in tall confining buildings and massive shopping malls. Such things are considered unrefined forms of entertainment.
