On April 4-5, 2023, GGR Researcher and the Dean of the School of International and Public Policy, Professor Nobumasa Akiyama, participated in the Second Meeting of the International Group of Eminent Persons for a World without Nuclear Weapons in Tokyo. Three Japanese and six foreign commissioners attended the session in person, and five foreign delegates joined the meeting online. At the conference, committee members from both nuclear weapons states and non-nuclear weapons states discussed the current security environment, the maintenance and strengthening of the NPT regime, and the situation surrounding the New START. The significance of summarizing the contents of the meeting as a concrete message was confirmed, focusing on maintaining and strengthening the norms, concrete nuclear disarmament, arms control, confidence-building measures, and measures to strengthen the NPT operational review process. The committee members who participated face-to-face also paid a courtesy call on Prime Minister Fumio Kishida and exchanged views with the union of diet members on disarmament-related issues.
