From March to May 1954, the U.S. conducted six hydrogen bomb tests in the Marshall Islands. In total, 67 atmospheric nuclear tests were conducted there. It is estimated that more than 10,000 Japanese fishermen and 990 fishing boats were affected by the nuclear testing in the Pacific. To this day, the governments of the United States and Japan continue to deny the claims of the fishermen affected by the nuclear tests. Their voices and struggles were deliberately suppressed and erased from history.
