Ukrainian President Volodymyr Zelenskyy met a survivor of the 1945 atomic bombing of Hiroshima when he visited the city's Peace Memorial Museum.
Zelenskyy spent about 40 minutes at the museum on Sunday evening.
The museum was closed to the public during Zelenskyy's visit.
The 85-year-old survivor, Ogura Keiko, said Sunday she met the president and told him about her experience.
Ogura said she also spoke to Zelenskyy about a young victim of the attack, Sasaki Sadako.
Sasaki died of leukemia at the age of 12. The figure at the top of the Children's Peace Monument in the Peace Memorial Park was modeled after her.
Ogura met G7 leaders at the museum on Friday. She says she also talked with leaders of non-G7 countries during their visit to the museum on Sunday morning.
Ogura was eight years old when she was exposed to radiation from the 1945 explosion. She has been working as a guide for foreigners visiting the park and sharing her experience in English with people around the world.
