I majored in international politics at the Graduate School of Political Science, Waseda University and started my academic career at Matsuyama University as a full-time lecturer in 1996. I then served as: an assistant professor at Matsuyama University; a visiting researcher at the Institute for Peace Research and Security Policy, University of Hamburg; and Researcher-in-Residence at the Prague office of the Secretariat of the Organization for Security and Co-operation in Europe (OSCE), before joining the faculty of Ritsumeikan University in 2004. I also served as a visiting researcher at the Institute for European, Russian and Eurasian Studies, George Washington University from 2009 to 2010, and as a visiting scholar at the National University of Mongolia in 2017.

Why did the Cold War end? To answer this question, I began studying the human rights issues of the Eastern Bloc countries in light of their relations with the Organization for Security and Co-operation in Europe (OSCE) and Western diplomacy. Today, I am researching the support for democratization provided by the OSCE after the Cold War, and security issues of Mongolia and other North-East Asian countries. I teach “International Public Policy” and “Peace and Democracy” to undergraduate students and “International Politics Research” to graduate students. In my seminar, I teach international politics through a gaming approach.
I also conducted research on more than 70,000 Russian soldiers in the prisoner-of-war camp set up in Matsuyama in the 1904-05 Russo-Japanese War. Recently, I authored International Politics in War and Democracy based on the concept of the Cold War period, co-translated In Defense of the National Interest, a classic book authored by Hans Morgenthau, and edited Geopolitics over Resources and Reasons behind the Russian Invasion of Ukraine.

In this era of globalization, it is increasingly necessary to incorporate global perspectives in the public policy-making process. Accordingly, greater importance is placed on research on how international organizations, national governments, NGOs and CSOs should cooperate and share problem-solving tasks with each other. In this light, it is useful to simulate international negotiations using the role-playing method to examine a policy-making process and its consequences ,especially in the crisis or tragedy like the Russo-Ukrainian war. We can make considerable progress in solving international conflicts by identifying the true interests of the negotiation partners and understanding their patterns of behavior.
