Seeking permission to visit a sumo stable to watch the wrestlers in training is a difficult process in Japan and visits are discouraged by the sumo stables. When you are finally permitted to view the morning training (Asa Geiko), there are further constraints: you must not talk; you must sit on the floor with your legs tucked under you; you must not move in this position; you must never enter the training ground; you must never address the ranked sumo wrestlers; you must not show that you are “relaxed” in your demeanour; you must not make any noise, and that includes your mobile phone (must be shut off) and your camera (the “beep” sound must be turned off).

These photographs were all I could do to capture these sumo wrestlers in training.
