Hiroshima commemorates the atomic bomb victims – and debates Japan’s defense policy

Hiroshima – 06/08/2026: In Hiroshima, thousands of people commemorated the victims of the American atomic bombing on August 6, 1945, on the 81st anniversary of the attack. The central ceremony began in the morning at the city’s Peace Memorial Park; at 8:15 a.m., the time of the explosion, those present observed a minute of silence. Mayor Kazumi Matsui combined the commemoration with a warning against the global reliance on military power and nuclear threats.

The bomb destroyed large parts of Hiroshima and killed an estimated 140,000 people by the end of 1945. The city holds its annual memorial ceremony for those killed and for the survivors, known in Japan as Hibakusha. The ceremony included the mayor’s peace declaration and an address by children. Doves were released, followed by a peace song.

Matsui criticized states that disregard international rules and use nuclear weapons as a means of political pressure. He rejected the notion that nuclear deterrence could provide lasting security. Political leaders must draw concrete conclusions from Hiroshima’s history for disarmament and the peaceful resolution of conflicts.

The commemoration took place amid a domestic political dispute over Japan’s defense policy. The government in Tokyo plans to revise its key security documents in 2026, including the National Security Strategy. Critics fear that the realignment could further weaken the country’s military restraint maintained since the end of World War II. Japan’s security framework continues to be based on its pacifist postwar constitution, while the government has increased defense spending and expanded military capabilities in recent years.

Peace initiatives and opponents of further rearmament invoke the experiences of Hiroshima and Nagasaki in this debate. They oppose a policy that places greater emphasis on deterrence and warn against a gradual departure from postwar principles. The controversy therefore extends beyond historical memory: it concerns Japan’s position in East Asia and its approach to the region’s growing security conflicts.

Prime Minister Sanae Takaichi, according to the Associated Press, said that Japan continues to uphold its three non-nuclear principles. Under these principles, the country neither possesses nor produces nuclear weapons and does not allow them to be stationed on its territory. However, according to the report, she did not explicitly pledge to preserve these guidelines unchanged in the upcoming revision of the security strategy.

The memorial days also recall the second American atomic bombing: Nagasaki was struck on August 9, 1945. The ceremony there marking the 81st anniversary is scheduled for August 9, 2026.
