Ōishi Matashichi (大石又七) was a Japanese anti-nuclear activist and author, and was a fisherman exposed to the radioactive fallout of the Bravo Nuclear Test in the Marshall Islands on March 1, 1954. He was one of twenty-three fisherman on the vessel Daigo Fukuryū Maru. Their catch of tuna and shark was also found to be contaminated with radiation, resulting in two tons of tuna buried at Tsukiji fish market instead of being sold. Members of the crew suffered from acute radiation syndrome, with Kuboyama Aikichi dying of a related infection six months later. Ōishi was hospitalized for several months. He quit the fishing industry and moved to Tokyo to open a laundromat, which he ran for fifty years. His first child was stillborn and he later developed liver cancer.
