This series was inspired by Haruki Murakami's novel 1Q84. In the novel, Tengo was waiting for Aomame on a slide in a deserted playground during the night. I happened to come across the same scene when I walked around a playground nearby with my dog. There was no one but us and a slide and swing in silent darkness. His novels always contain some kind of fantasy in which we might lose the borderline between reality and unreality. In the deserted playground, somehow I felt strange air. I hope you will find unreality in realty in these pictures of playgrounds.
