About 78 percent of atomic bomb survivors are finding it difficult to pass on their experiences of the 1945 bombings in Hiroshima and Nagasaki, a Kyodo News poll showed Friday, highlighting the challenges and limitations presented by aging.

Held ahead of the 75th anniversary of the U.S. bombings in August, the survey also found that 63.1 percent of the survivors think the global outbreak of the novel coronavirus is preventing them to some extent from promoting the abolition of nuclear weapons.

The issue of passing on memories of the bombings is becoming more urgent as witnesses are declining in numbers.
