チケット購入・視聴はこちら →世界情勢が緊迫感を増すなかで、日本の安全保障上の立場は依然として不安定であり続けています。
米国の核抑止への依存、NPT体制の形骸化、中露北の核増強という三重の問題に対し、日本は何ができるのか。
本フォーラムは、これまで日本が避けてきた「核武装」という究極の選択について、その技術的・法的・政治的障壁を正面から議論する試みです。冷徹な現実主義に立った国防論を構築するための、日本の議論の転換点となることを目指します。
Yui Sakaki is a Tokyo-based nonfiction writer whose work focuses on security affairs, policy, and international relations. Her approach is deliberately non-partisan: rather than advocating for a position, she excavates the technical, economic, and institutional facts that allow readers to form their own informed judgments.
Her debut book, Japan’s Nuclear Armament I: Unknown Capabilities — Technology and Cost (Gogatsu Shobo Shinsha, November 2025), examines Japan’s latent potential through rigorous analysis of engineering feasibility and financial constraints — stripped of the ideological framing that dominates public debate.
Alongside her policy writing, Sakaki keeps a quieter notebook — Table Talk — where she explores the texture of daily life through short, contemplative essays. Both practices share the same discipline: patience with ambiguity, and respect for the space between information and conclusion.
Series · Vol. 1
A fact-based inquiry into whether Japan could develop nuclear weapons — examining material science, engineering constraints, and realistic cost envelopes. The first in a series that sets aside ideology to ask: what do the numbers actually say?
Series · Vol. 2 · Forthcoming
The second volume extends the inquiry into strategic, diplomatic, and legal dimensions — continuing the series’ commitment to evidence over advocacy.
With Prof. John J. Mearsheimer · University of Chicago
Meeting the scholars whose work has shaped the field — and bringing those conversations back to Japanese readers.
John J. Mearsheimer, the University of Chicago political scientist and author of The Tragedy of Great Power Politics, is one of the most influential voices in contemporary international relations theory. His framework of offensive realism — the idea that great powers are locked in perpetual competition for security — has become indispensable to understanding the current world order.
For Sakaki, encounters like this are not incidental to the writing — they are part of the research. Hearing an argument made in person, in its original language, changes how you understand it on the page.

Security policy attracts strong feelings — that is not a problem to be solved, but a signal worth attending to. Strong feelings tend to reach conclusions before the evidence does. Sakaki’s practice begins by deliberately slowing that process down.
The personal essays in Table Talk work by a different logic — not inference but accumulation. A detail held long enough starts to mean something. Both disciplines, she finds, share the same core: patience with what is not yet clear.
