While F-35 combat aircraft successfully released dummy nuclear bombs at a test exercise in Nevada, Japan announced the purchase of 105 F-35s from the United States. They seem to have forgotten that Japan is the only country victim of nuclear bombing: on August 6, 1945, the B-29 bomber Enola Gay dropped the atomic bomb Little Boy on Hiroshima, and on August 9, 1945, the B-29 bomber Bockscar dropped the nuclear bomb Fat Man on Nagasaki. Both nuclear attacks killed around 200,000 people, and the 4,000-degree Celsius explosion baked their shadows and left their mark on the ground. The shades of victims who lost their lives still lie on the ground.
Yukari Hirano (1984) and Tsubasa Kato (1984), known as Yukari Kato Tsubasa, are artists noted for their collaborative practice involving performance and video. Their representative Pull and Raise/Down (an ongoing series of performances in which large scale wooden structures replicating buildings or other monuments are pulled up/pulled down from/to the ground using ropes by a large number of participants) relies on spontaneous participation. Since completing a project in Fukushima after the 2011 disaster, their work has become more satirical, which plays with social boundaries. Their performance-related installations create an environment that bridges the gap between participants in the performance and viewers and creates a channel for multiple subjectivities to interact across space and time.
