Let's Look at the Special Exhibit
On March 1, 1954, the Lucky Dragon No. 5, a long-line tuna boat from Shizuoka Prefecture, was exposed to a U.S. hydrogen bomb test. All the crew members were exposed to the "ashes of death," and half a year later, Chief Radio Operator Aikichi Kuboyama died. The Special Exhibition introduces the damage that radiation inflicted on the Lucky Dragon No. 5 and the Marshall Islanders, as well as the suffering caused by the radiation released by the Hiroshima atomic bombing.

Encounter with a hydrogen bomb test
At 6:45 a.m. on March 1, 1954, the crew of the Lucky Dragon No. 5, an ocean-going long-line tuna boat, saw the western sky suddenly light up with a fireball. The fireball was the explosion of Bravo, the largest hydrogen bomb tested by the United States at the Bikini Atoll. Two or three hours later, highly radioactive ash began falling on the boat. It stuck to the bodies of the crew and they breathed it in through their noses and mouths. These "ashes of death" caused various symptoms in the crew: headache, vomiting, eye pain, bleeding from the gums, hair loss, and more. All 23 were victims of acute radiation poisoning.

The death of Chief Radio Operator Aikichi Kuboyama
On March 14, the Lucky Dragon No. 5 returned to Yaizu Port. The news that the crew, the boat, its fishing gear, and its tuna catch were all heavily contaminated with radiation shocked the entire country. Toward the end of March, the crew were hospitalized in Tokyo hospitals and placed under the care of a team of physicians. Despite the hard battle fought by the treatment team, Chief Radio Operator Aikichi Kuboyama (then 40) died on September 23.
