The fact that 992 Japanese vessels wereexposed to radiation due to U.S. nuclear tests is little known. More than10,000 sailors were affected, many of them young men in their teens tothirties. The red dots on the map indicate the locations where 356 of thesevessels caught tuna.

In 1985, high school students in Kochi,Japan, met a Nagasaki atomic bomb survivor whose son, a fisherman, had alsobeen exposed to nuclear tests in the Pacific. He fell ill and later took hisown life at 27. As the investigation continued, ex-sailors recounted fallingwhite ash and high rates of cancer and leukemia.

The sailors have repeatedly demanded truthand compensation, but the Japanese government has refused to respond. Articles6 and 7 of the TPNW call for assistance to individuals affected by the use andtesting of nuclear weapons. The sailors and their families stand with Hibakushaworldwide, determined to fight for the rights enshrined in the treaty.
