Hiroshima Roundtable
In order to make the “Supporting the Roadmap for the Abolition of Nuclear Weapons” in the “Hiroshima for Global Peace Plan” more concrete, we have annually held the Hiroshima Roundtable since 2013 as a place to have a multi-lateral and international discussion on nuclear disarmament and arms control.
This conference has been held every year except for 2020, when it was canceled due to the spread of the new coronavirus, and the 13th conference was held in September 2026.
Hiroshima Roundtable 2026
On Wednesday, September 2, and Thursday, September 3, 2026, the "Hiroshima Roundtable 2026" was convened. Experts from various countries projected nuclear weapon trends over the coming year, discussed concrete measures to build a strong foundation for a peaceful international community free of nuclear weapons, and compiled their findings into policy recommendations.

The press conference for “Hiroshima Roundtable 2025”
Hiroshima Watch
Overview
- “Hiroshima Watch” is a policy proposal that questions the implementation of countries' commitments to nuclear disarmament and urges action to realize a peaceful world free of nuclear weapons.
- While the “Hiroshima Report” is an objective analysis that scores the actions of nuclear weapon states and major non-nuclear weapon states in the fields of nuclear disarmament, nuclear non-proliferation and security for each year based on certain criteria, the “Hiroshima Watch” is a compilation of expert opinions that aims to raise awareness of nuclear weapons issues in civil society and to make policy recommendations to each country on pressing issues surrounding nuclear weapons.
- For details, please refer to the “Hiroshima Watch” page.
