I stalks through Tokyo in search of chance encounters. Photographing people in the street, instinctively and on the fly, is a full-time challenge. each person you've photographed links up with the sensibility of the others. We're all involved in the same comedy. But there's a moment when you become your own best actor: amusement, anger, hate, pity, gravity – these feelings send me a signal, like an electric pulse, that makes me press the button. It's that snapshot, that moment of spontaneity, that you have to catch.
