Yumi Hiwatari
Professor of International Relations, Sophia University

Yumi Hiwatari was a Visiting Fellow at CIS in 2005–06. She is a Professor of International Relations at Sophia University in Tokyo and has written widely on U.S.-Japan relations and Japanese defense politics. Her previous research interests concern the comprehensive review of Japan’s defense policy, especially the policy changes that took place during the Koizumi administration and their impact on Japan’s Self-Defense Forces. She has an essay on that topic in Breakthroughs, Spring 2006.  In 2012, Hiwatari finally finished her book on Japan's national security, Defending Strategy: Rethinking Japan's National Security (Senshu Bouei Kokufuku no Senryaku). The publisher is Minerva Shobo Japan. The book consists of five chapters, including strategy, U.S.-Japan alliance, defense budget, structural reform, and civil-military relations. It is available only in Japanese.

Her current research topic is organizational transformation of the Japan Maritime Self Defense Force since the end of the Cold War, which could be one of the most effective ways to analyze Japan’s national defense. Hiwatari is Chairperson of the Department of Global Studies and Director of the Sophia Institute of International Relations. Faculty of Global Studies was established in April 2014 and the Sophia Institute of International Relations in July 2015. She received her Ph. D. at the University of Tokyo in 1989. She was a Visiting scholar at UCLA from 1991-1993.
