Daigo Fukuryū Maru
At first, the US claimed that the extent of the "Lucky Dragon" incident contamination was trivial. Later, the United States paid Kuboyama's widow and children the equivalent in yen of about $2,800 ($26,700 in 2020). The tragedy of the "Daigo Fukuryū Maru" gave rise to a fierce anti-nuclear movement in Japan, rising especially from the fear that the contaminated fish had entered the market. The Japanese and U.S. governments negotiated a compensation settlement, with the transfer to Japan of a compensation of $15,300,000, of which the fishery received a compensation of $2 million, with the surviving crew receiving about ¥ 2 million each, ($5,550 in 1954, $52,800 in 2020). It was also agreed that the victims would not be given "hibakusha" status. The Japanese government pledged that it would not pursue further reparations from the U.S. government.
