What can we trust without reserve is?That is ordinary.It means common sense we have.I think that time to consider our ordinary get shaken by Tohoku disaster violently. There is a historical Greek word "Pharmakon".It means ambivalent relation such a pharmacy and poison.I behave as an artist as "Pharmakon",because art is not always beauty which occur the positive feelings.I think that is not art for art sake.I propose the art for seamless experiences with our living life.I reconstruct into the installation with gaps and cracks by shaking our stereotype. That makes clear and more comprehensible social problems we hard to see.
