Eli’s interest in U.S.-Japan nuclear policy began when he met a group of hibakusha (Hiroshima and Nagasaki atomic bomb survivors) and heard them advocate for nuclear disarmament. These testimonies stimulated his interest in U.S.-Japan diplomacy as he began exploring the U.S.-Japan security relationship and the cornerstone of this correspondence, the U.S.-Japan Security Treaty.

Miho Kawamoto was born in Hiroshima and is passionate about becoming an expert in the fields of nuclear security and non-proliferation. During her time abroad in the U.S. as a high school exchange student, she was astonished to find that she was the only student in the American History class who believed that using the atomic bomb against Japan during World War II was not justified. She became aware that such a difference might have arisen from the fact that she knew the stories of atomic bomb survivors, while her American classmates did not. Such divergent views resulted in further developing her interest in nuclear deterrence. Her curiosity in this topic drove her to focus on international politics and security issues surrounding nuclear weapons during her undergraduate studies. After graduating with a Bachelor of Law and International Politics, she enrolled into Hitotsubashi University’s Graduate School of International and Public Policy to increase her knowledge, and to pursue her dream of becoming a policy expert.
