Gaku Tsutaja's painting refers to a widely known secret project. "What you see here, what you do here, what you hear here, when you leave here, let it stay here" was the message for the scientists and workers who took part in the Manhattan Project, which ended up creating the atomic bombs that were dropped on Hiroshima and Nagasaki in 1945. This Confucian idea is also known in Japan. This work connects two drastically different sides in the historical event with positive and negative. Tsutaja created this painting inspired by the sign that used to be at Oak Ridge, Tennessee.
