How Long is a String is a direct outgrowth of the long, explorative walks I often take late at night. I begin such walks without a plan, navigate by arbitrary means, and destroy many, many pairs of shoes. Walking at night reveals Tokyo as a place of quiet isolation not typically seen during the day and never imagined by those who only know this place by its portrayal in the media. Empty of people, but filled with questions. Where does this road lead? What’s behind that wall? Am I the only one here? Some of these never get answered.
