The first in a series of high-yield thermonuclear device tests, the Castle Bravo weapon was detonated on March 1, 1954 at Bikini Atoll. The weapon's 15 megaton yield is the largest ever tested by the United States. The Castle Bravo test and the ensuing radioactive fallout from the explosion led to a wave of protests, particularly throughout Japan, where the explosion was compared to the attacks on Hiroshima and Nagasaki. These tests left an indelible mark on the Japanese psyche and have been frequently referenced in Japanese popular culture.
