Miyajima walks across the scramble crossing. Suddenly, he shouts out loud " Ahhhhh!!! ". Then, as if nothing happened, he goes away. Someone records the performance on a video and photo. It is recorded that a voice (artificiality) makes noise, and the sound ripples through the town (nature), but the town (nature) goes back to nature again.
This type of performance tried several places in Japan until 1983.
