In a matter of seconds, the cities were destroyed and countless lives lost. These two cities were the first in human history to experience the unparalleled power and devastation of atomic bombs. Three days later, the B-29 Bockscar dropped “Fat Man,” a plutonium bomb, over Nagasaki. On August 6, 1945, the B-29 Enola Gay released “Little Boy,” a uranium bomb, upon the population of Hiroshima. Through March 1, 2020, the exhibition will include a special display of artifacts belonging to atomic bomb victims. To commemorate the upcoming 75th anniversary of the bombings of Hiroshima and Nagasaki, the Japanese American National Museum presents Under a Mushroom Cloud: Hiroshima, Nagasaki, and the Atomic Bomb, organized in partnership with the cities of Hiroshima and Nagasaki.
