Hiroshima Marks 81st Atomic Bomb Anniversary Amid Nuclear Policy Debate
People in Hiroshima, Japan, remembered a very sad day from long ago.
On August 6, 1945, an American bomber plane dropped an atomic bomb on the city, and about 140,000 people died.
Three days later, another bomb hit Nagasaki, killing 70,000 people, and World War II soon ended.
Every year, Hiroshima holds a ceremony to remember the victims, and this year was the 81st anniversary.
The city's mayor told world leaders that nuclear weapons are too dangerous and should not be used to scare other countries.
Japan's Prime Minister came to the ceremony for the first time, saying she wants a world where nuclear weapons are never used.
Some people worry the government might change Japan's old rules that keep nuclear weapons away.
Only about 91,000 survivors are still alive, and they are very old, so they want people to never forget.
The United Nations said the lesson of Hiroshima is to build a world where these weapons become unthinkable.
Hiroshima held its 81st anniversary ceremony for the U.S. atomic bombing at Hiroshima Peace Memorial Park, with about 50,000 people attending.
Mayor Kazumi Matsui criticized major powers for waging wars and urged them to stop justifying the possession of nuclear weapons as deterrence.
Prime Minister Sanae Takaichi attended the memorial for the first time, pledging a "realistic approach" to a world where nuclear weapons are never used.
There is speculation Takaichi's hawkish government may ease Japan's postwar three non-nuclear principles when it compiles new security documents.
Atomic bomb survivors have fallen to 91,105, with an average age exceeding 86, as they worry about fading memories of the attack.

Nuclear Deterrence Supporters
Nuclear deterrence vs. abolition
Anti-Nuclear Advocates
Mayor Matsui and survivors say deterrence legitimizes violence and "pushes a world without nuclear weapons further into the distance."
Nuclear Deterrence Supporters
Many political leaders still consider nuclear deterrence a realistic approach, and Japan relies on the U.S. nuclear umbrella for protection.
Japan's three non-nuclear principles
Anti-Nuclear Advocates
Survivors and the mayor want Japan to keep its postwar three non-nuclear principles and move toward a world without nuclear weapons.
Nuclear Deterrence Supporters
Prime Minister Takaichi has advocated a review of the principles, including the possibility of dropping the third one barring nuclear weapons from being brought into the country.
Treaty on the Prohibition of Nuclear Weapons
Anti-Nuclear Advocates
Survivors want Japan to sign the Treaty on the Prohibition of Nuclear Weapons or attend its meetings as observers.
