Barack Obama will this month become the first sitting US president to visit atomic bomb-struck Hiroshima , but the White House said he will not offer an apology for the devastating attack on the Japanese city in 1945.
Obama, accompanied by Prime Minister Shinzo Abe, will make the deeply symbolic visit on May 27, after attending a G7 summit in south-central Japan , his spokesman Josh Earnest said Tuesday.
On August 6, 1945, the US dropped the world's first atomic bomb on Hiroshima , killing around 140,000 people, including those who survived the explosion itself but died soon after from severe radiation exposure.
The bombings remain controversial in the United States and across the world, with opinion sharply divided on whether their use ended the brutality of World War II and avoided a bloody US invasion of Japan , or whether dropping atomic weapons on civilians constitutes a war crime .
A Pew poll last year showed 56 percent of Americans think the bombing was justified, while 14 percent of Japanese do. In both countries, approval of then US president Harry Truman 's order has waned dramatically over the years.
In Hiroshima , Obama will visit the once ruined city's Peace Memorial Park "where he will share his reflections on the significance of the site and the events that occurred there," said senior Obama foreign policy advisor Ben Rhodes.
Kerry said he was "deeply moved" by the experience and called a museum at the site a "gut-wrenching display that tugs at all your sensibilities as a human being."
"Everyone should visit Hiroshima , and everyone means everyone," he added, fueling speculation that Obama would go.
- No apology -
"It is significant for him to send a message of his determination for a nuclear-free world. For a US president, it was a big decision," he said.
But some have been concerned that Obama's visit would be seen as an apology for events of seven decades ago.
A presidential visit will rile Obama's opponents and some in the military, whose predecessors carried out presidential orders to drop the bombs.
The visit would come at a particularly sensitive time. This December marks the 75th anniversary of Japan 's attack on Pearl Harbor, in Obama's home state of Hawaii.
But the White House was eager to stress that Obama's visit is not an apology.
"He will not revisit the decision to use the atomic bomb at the end of World War II. Instead, he will offer a forward-looking vision focused on our shared future," said Rhodes.
The visit is likely to have regional reverberations, at a time when North Korea, a short distance away, is aggressively pursuing its nuclear and ballistic missiles development program.
At a four-day Communist Party confab that ended on Monday, Pyongyang's enigmatic leaders vowed to continue building weapons systems that have already prompted deep international sanctions, opprobrium and isolation.
Japan 's neighbors in China and South Korea will also be watching the visit closely, always eager to make sure that their once hyper-aggressive foe is not allowed to play the role of a World War II victim.
Obama will deliver a speech on US-Vietnam relations in Hanoi and also visit Ho Chi Minh City.
