I got an opportunity to install a sound installation on an uninhabited island that still retains historical sites from the Meiji era. Since there was no power supply, I explored the island, wondering what to do, and came across an ammunition depot about waist-high. Upon entering it, the world I had just been in was suddenly framed like a scene on a screen, and the surrounding sounds were limited to those coming from the direction of the opening. The interior extended deep, and the further in I went, the more I felt as if I were observing the previous space objectively, or as if I had been cut off from the world.

As a sound installation that does not use speakers, I installed high quality sound-absorbing panels on the inner walls of the ammunition depots and tunnels, thoroughly absorbing sound from directions other than the front, creating nine depots from which sound appears to emanate from the framed scenery. Since each entrance opened in a different direction, one depot, for example, carried the engine sounds of a ferry moored nearby; another, facing the U.S. Yokosuka Naval Base, captured the sounds of airplanes; the opposite one clearly conveyed the sounds of trees and birds.
