One day marks 70 years since the tuna fishing boat Daigo Fukuryu Maru was exposed to radiation in an American hydrogen bomb test. Approximately 1,000 people from all over the country gathered at a rally held in Shizuoka City on the occasion, calling for the abolition of nuclear weapons.

On March 1, 1954, the United States conducted a hydrogen bombtest at Bikini Atoll in the Marshall Islands, which caused so-called "ashes of death" containing radioactive materials to fall.
