What are these footprints? Akiko Arita described her work as follows: "Within the endless flow of time, every event is simply the momentary repetition of life and death, in order to understand this, we can only look to some remaining traces or knowledge that have been passed down to us. This pattern of footmarks expresses the process of people's actions that took place in this space in the past. While these actions should be meaningless to us, the process of awareness, thought, and will that brought about these actions transcends the passage of time and they still dominate the space, exerting a powerful influence over us." We do not know to whose or what manner of life this trace belongs. However, people follow in these footmarks without realizing it and look back over them. That is the power this work has over the viewer.
