You stand in the dirt and see the boundary. The boundary between your home and your neighbors. The boundary between your town and the next. All you have to do to see it is stand in the dirt. It also helps that there is a boundary sign standing in the dirt that you can also see.

The boundary you're looking at is the Kyoto (きょう) boundary. Kyoto is a really famous, important place, so if you think about it, everything could be the boundary between where you are and Kyoto if you just make them really big.
