April 27

Observing the Opening Session of the 11th NPT Review Conference

At the opening session, following introductory remarks by UN Under-Secretary-General and High Representative for Disarmament Affairs Izumi Nakamitsu, the Conference proceeded with the election of its President and Vice-Presidents, as well as an address by UN Secretary-General António Guterres. During discussions on the election of the Vice-Presidents, delegates from various countries engaged in statements and exchanges of views, reflecting tensions surrounding issues such as nuclear development. Witnessing these proceedings firsthand, the Youth participants gained a deeper understanding of the complex realities of the international community and the challenges of building consensus on nuclear disarmament and non-proliferation, even within the NPT framework—the largest multilateral mechanism addressing these issues, including both nuclear-weapon and non-nuclear-weapon states. At the same time, one participant reflected that “precisely because the international situation is so uncertain and turbulent, this Conference serves as an extremely important forum for dialogue between nuclear-weapon and non-nuclear-weapon states.” Through this experience, the Youth participants further deepened their awareness of the role they themselves can play in advancing peace and nuclear disarmament.

Observing the Opening Session
Attendance at the Opening Ceremony of the UN Atomic Bomb Exhibition Hosted by Nihon Hidankyo and Co‑hosted by Hiroshima and Nagasaki

The Youth participants attended the opening ceremony of the UN Atomic Bomb Exhibition held in the Visitors’ Lobby of UN Headquarters. The exhibition was organized to share the experiences of atomic bomb survivors and their wish that “no one should ever suffer the same tragedy again.” This marked the fifth time the exhibition had been held at the United Nations. In his opening remarks, Mayor Matsui emphasized the significance of holding the exhibition during the NPT Review Conference, particularly at a time when the international security environment remains challenging despite Nihon Hidankyo having been awarded the Nobel Peace Prize in 2024. He called on participants to take to heart the realities of the atomic bombings and to deepen discussions on nuclear disarmament. Following the ceremony, the Youth participants reflected on the importance of conveying the realities of the atomic bombings to a wider audience, commenting that the exhibition was “an important opportunity to communicate the horrors of nuclear weapons” and expressing their hope that “many people will have the chance to see it.” Through the exhibition, they renewed their awareness of the importance of sharing the realities of the atomic bombings with people around the world.

Attending the Ceremony
Visit to UNICEF (United Nations Children’s Fund)

The delegation visited UNICEF and received a briefing from Finance Specialist Mr. Kageyama and Public Partnership Officer Ms. Haramoto on UNICEF’s mission, as well as their professional responsibilities and career paths. During the Q&A session, the youth participants asked questions about what inspired them to pursue careers in international organizations and how students should engage with global social issues. In response, the speakers emphasized the importance of maintaining an interest in world affairs, the value of seeing conditions on the ground in different parts of the world while still a student, and the appeal of working in international organizations where people from diverse backgrounds collaborate toward common goals. The visit provided the youth participants with a valuable opportunity to reflect on their future activities and career aspirations.

Meeting with Ambassador Ichikawa, Permanent Representative of Japan to the Conference on Disarmament

The youth delegation met with Ambassador Ichikawa, Permanent Representative of Japan to the Conference on Disarmament, and the youth representatives introduced the peace activities they had been engaged in to date.

In response, Ambassador Ichikawa emphasized the importance of not only focusing on whether one supports or opposes nuclear weapons, but also seeking to understand why people hold those views and engaging in dialogue while identifying common ground. She also encouraged the youth participants by stressing that it is important for younger generations to carry forward the message of peace.

They began the visit by sharing breakfast with UNIS students, engaging in conversations on everyday topics and deepening their mutual understanding. This was followed by a gallery walk, during which the delegates viewed and discussed posters created by students on topics such as the atomic bombings, nuclear power plant accidents, and nuclear weapons development. The session also included opportunities for questions and discussion. At the subsequent Upper School Assembly, presentations and a question-and-answer session were held with the mayors of Hiroshima and Nagasaki, as well as representatives of the youth delegation.

They emphasized the importance of young people taking action and engaging in dialogue. In response to a question about how young people can contribute to peacebuilding efforts, they spoke from their own experiences about the effectiveness of using social media to raise awareness and share messages. The visit concluded with a peace ceremony presented by fourth-grade elementary school students, featuring welcome cards and a choral performance. Following the visit, the youth delegates shared reflections such as, “Considering issues from the perspectives of people in other countries helped me better understand others,” and “I would like to apply the presentation techniques and organizational methods I learned during the gallery walk to my future activities.” The experience inspired the participants to further strengthen their commitment to future peace initiatives.

During the subsequent question-and-answer session, the youth delegates asked about refugee admission systems and the gap between ideals and realities in refugee protection. In response, Ms. Bitetti explained the principles of international law and the roles and responsibilities of individual countries. She also emphasized the importance of paying attention to each person’s circumstances and addressing challenges step by step. Following the visit, one youth delegate commented, “Even when wars are caused by governments or military forces, it is cities and ordinary citizens who ultimately suffer the greatest impact and harm. That is why I believe it is important to continue expanding networks for peace.” The visit provided a valuable opportunity for the participants to deepen their understanding of peacebuilding and humanitarian assistance.

Attendance at the NGO Session of the 11th NPT Review Conference

The youth delegates attended the NGO Session of the 11th NPT Review Conference, where civil society organizations from around the world, including Mayors for Peace and atomic bomb survivors’ organizations, delivered messages to government representatives on behalf of citizens. During the session, the delegates listened to speeches by representatives of the Japan Confederation of A- and H-Bomb Sufferers Organizations (Nihon Hidankyo), Mayors for Peace President Kazumi Matsui, Vice President Shiro Suzuki, the Governor of Hiroshima Prefecture, and the Vice Governor of Nagasaki Prefecture, among others. Following the session, the youth delegates shared their reflections. One youth delegate commented, “I was reminded that nuclear issues are not problems for any particular country alone, but challenges that all of humanity must confront together.” Another noted, “We need to consider new approaches to security that do not rely on nuclear deterrence. To achieve this, it is essential to foster a culture of peace at the grassroots level and embed it within society.”

Reflections on the Mayors for Peace Youth Delegation

  • Through this delegation, I was confronted with the harsh realities of the current international situation and was led to reflect deeply on fundamental challenges, including the limitations of dialogue and the question of how nations can be encouraged to see reducing nuclear weapons as a safer option. This experience reinforced my belief that our generation, which will shape the future, must sincerely engage with these difficult issues and continue to raise awareness from Hiroshima, the atomic-bombed city, about the dangers of nuclear weapons.
  • Through the many people I met during this delegation, I came to realize once again that my volunteer activities as a guide at the Hiroshima Peace Memorial Park had primarily been directed toward people who visited Hiroshima with an interest in peace. Because not everyone in the world is concerned about nuclear weapons or peace-related issues, I felt it is important to reach out beyond Hiroshima, raise awareness among a wider audience, and expand opportunities for dialogue.
  • Through this delegation, my perception of peace, nuclear weapons, and international relations changed significantly. Hearing directly from United Nations staff members and professionals working in international organizations about the realities of their work and their personal experiences gave me an opportunity to think deeply about my future career. The world, which had previously seemed distant and abstract, now feels much closer to me. This experience strengthened my desire to continue learning about international relations and to contribute to the world in the future.
  • Through this delegation, I learned the importance of thinking critically while taking action. The United Nations staff members and professionals working in international organizations whom I met during the delegation were all confronting various challenges and continuing to act, each through a different approach. I came to realize that their actions were supported by extensive learning and deep reflection. Going forward, I hope to remain interested in a wide range of issues, continue learning, and place great importance on thinking for myself and taking action.
