Summary On May 18, 2023, Asahi Shimbun introduced an article that interviewed Professor Nobumasa Akiyama, Dean of School of International a­nd Public Policy, Professor at Graduate School of Law, a­nd GGR Researcher, titled “World Without Nuclear Weapons, However Long It May Take: Expectations of Japanese Researcher for the Hiroshima Summit.“ In this article, Professor Akiyama discussed what the G7 should voice toward "a world without nuclear weapons.” First, Professor Akiyama argued that, based on rising tensions among the major powers a­nd in the region, there will probably be virtually no linear progress toward “a world without nuclear weapons.” The professor then stated that building a track record of nuclear weapons not being ultimately used under any circumstances is important for achieving “a world without nuclear weapons,” even though it may seem like a slow a­nd roundabout way to go. The professor stressed the importance of bridging the gap in perceptions of nuclear weapons due to the different geopolitical risks that countries face to strengthen cooperation between emerging a­nd developing countries in the nuclear field. In addition, regarding China's nuclear weapons, the professor explained that the lack of disclosure of nuclear-related information has created a major transparency problem.
