Kohei Yoshiyuki en su serie de fotografías "Park" captura el voyeurismo nipón, parejas realizando el acto sexual en los parques públicos rodeados de voyeurs.
"Before taking those pictures, I visited the parks for about six months without shooting them," Yoshiyuki wrote recently by e-mail, through an interpreter. "I just went there to become a friend of the voyeurs. To photograph the voyeurs, I needed to be considered one of them. I behaved like I had the same interest as the voyeurs, but I was equipped with a small camera. My intention was to capture what happened in the parks, so I was not a real 'voyeur' like them. But I think, in a way, the act of taking photographs itself is voyeuristic somehow. So I may be a voyeur, because I am a photographer."
"The couples were not aware of the voyeurs in most cases," he wrote. "The voyeurs try to look at the couple from a distance in the beginning, then slowly approach toward the couple behind the bushes, and from the blind spots of the couple they try to come as close as possible, and finally peep from a very close distance. But sometimes there are the voyeurs who try to touch the woman, and gradually escalating — then trouble would happen."
