In the fall of 2022, the Weatherhead East Asian Institute (WEAI) at Columbia University inaugurated a new program directed by Professor Gerald Curtis that focuses on Japan’s evolving foreign policy strategy. Named the Japan Research Program, it incorporates and builds on activities that were previously sponsored by the Institute’s Toyota Research Program. The Japan Research Program continues to enjoy the generous support of Toyota and is currently seeking support from other corporations, foundations, and individuals for its public policy-related events and activities concerned with Japan’s relations with the United States, with other countries in the Indo-Pacific region and globally.
Columbia University’s Japan Research Program is pleased to publish the following research by Greg Rattray and Seungmin (Helen) Lee on US-Japan cyber cooperation. It provides an important overview of developments in Japanese cybersecurity policy and actions since the adoption of a new National Security Strategy in December 2022 and offers several important recommendations for strengthening Japan’s cybersecurity defences and better integrating Japanese and US cybersecurity policies. It emphasizes the importance of Japan developing a strong security clearance system, recruiting more cyber specialists, enhancing its cyber preparedness, and increasing collaboration in cybersecurity with the United States.
The authors wish to thank US Admiral (ret.) Dennis Blair and NTT CEO Shinichi Yokohama for their advice and review of the paper and the Japan Research Program at Columbia University’s Weatherhead East Asian Institute and its Director, Gerald Curtis, for support for the publication of this research.
