In Japanese kyudo, archers use traditional asymmetric bows over 2 meters long as they attempt to strike a target from a distance of either 28 or 60 meters. Self-mastery is key in this exacting martial art, where the target is said to reflect the heart, and correct attitude and technique are seen as intertwined. We use a high-speed camera to track the path of a skilled archer's arrows as they fly through the air, shining a light on the depth and subtleties of kyudo's hidden techniques.
