第五福竜丸
After being released from the hospital, Oishi Matashichi left his hometown to open a dry cleaning business. Beginning in the 1980s, he frequently gave talks advocating nuclear disarmament. His first child was stillborn, which Oishi attributed to his own exposure to radiation. In 1992, Oishi developed cirrhosis of the liver but recovered after successful surgery. In 2011, he published a book titled, "The Day the Sun Rose in the West: Bikini, the Lucky Dragon and I" in English. The book combines his personal story, the story of the "Daigo Fukuryū Maru", and declassified documents between the Japanese and American governments about the fallout's damage.
