Espreso TV reported the information.
DW reported that the summit adopted a joint statement on Ukraine.
"We are renewing our commitment to provide the financial, humanitarian, military and diplomatic support Ukraine requires for as long as it takes," the document says.
The G7 also stated that it would oppose Russia's illegal, unjustified and unprovoked war.
European Commission President Ursula von der Leyen posted a video on Twitter from Hiroshima.
"What happened in Hiroshima continues to haunt humanity. Here we remember the terrible cost of war. And we are reminded of our duty to preserve peace," she wrote.
Kyodo reported the information.
Ukrainian National Security and Defense Council (NSDC) Secretary Oleksiy Danilov confirmed on the United News national telethon that President of Ukraine Volodymyr Zelenskyy would personally attend.
"Who would doubt that our president will not be present there (at the G7 summit in Hiroshima - ed.). We were confident that our president would be wherever the country needs him, anywhere in the world, to address the issues of our country's sustainability," he said.
Danilov added that very important decisions will be made at the summit, and therefore the physical presence of the Ukrainian president is absolutely important for defending Ukraine's interests.
"It helps to explain, provide clear proposals and arguments for the events taking place in our country. When a person is somewhere far away across the ocean, they do not always have an understanding and sense of what is happening here. It is the physical presence of the President that is extremely important at such events," summarized the NSDC Secretary.
At the beginning of the summit, the G7 leaders visited a museum for the first time together, which houses evidence of the consequences of the atomic bomb dropped by the US military on this city in 1945.
After visiting the museum, the leaders walked to the cenotaph for the victims of the atomic bombing in the park and laid flowers. It was the first time that all the G7 leaders had visited a museum together.
Japanese Prime Minister Fumio Kishida, who chairs the meeting, chose nuclear disarmament as a key item on the summit's agenda against the backdrop of Russia's nuclear blackmail in the war in Ukraine and China's nuclear build-up.
He emphasized the need for leaders to take a close look at the "reality" of using the atomic bomb.
Biden is the second sitting US president to visit Hiroshima. The first to do so was Barack Obama, who visited the city in 2016, but such visits remain sensitive because many in the United States consider the two atomic bombs dropped on Japan to be a necessity that had to happen to end World War II.
French President Emmanuel Macron, British Prime Minister Rishi Sunak, and Canadian Prime Minister Justin Trudeau made the first-ever visits to Hiroshima by sitting leaders of their countries.
Japan remains the only country in the world to have been atomized. But in an effort to rid the world of nuclear weapons, the country, surrounded by unpredictable China, Russia, and North Korea, relies on the US nuclear umbrella for protection.
The Hiroshima Museum's collection contains about 100,000 relics, photographs, and other items, including burnt and tattered clothing, charred lunch boxes, and human hair that fell out due to radiation exposure.
British Prime Minister Rishi Sunak announces a ban on the import of Russian diamonds into the country at the G7 summit in Japan.
