What is the “Japan-U.S.
Alliance Study Project”?

Amid the paradigm of U.S.-China confrontation under the so-called “New Cold War,” this project seeks to review the Japan-U.S. alliance as a “public good” for the region and the international community, defining Japan’s security role in the new Japan-U.S. alliance and making recommendations for Japan’s security policy.


Project Outline

Japan U.S. Study Group

The group aims to redefine the significance of the Japan-U.S. alliance as a “public good” for the region and the international community and Japan’s defense system and study the specific areas for bilateral cooperation in response to the international situation. It seeks to pursue the optimum shape of the Japan-U.S. alliance as “public good” unbound by Japan’s domestic laws, geographical constraints, the current power balance, and other factors and make comprehensive recommendations on security strategy and policies based on an assessment of the military revolution, rapid military technological innovation, and so forth.
Specifically, joint research with the U.S. Heritage Foundation and collaboration with the Stockton Center of the U.S. Naval War College will be undertaken.

Cooperation with Other U.S. Allies and Partners

With China attempting to change the international order today, it is necessary to convert the relations between the U.S. and its allies into a network. As well as looking at the role Japan needs to play in order to contribute to the Japan-U.S. alliance, cooperation with the Central European nations -- which China regards to be its gateway to Europe -- will be strengthened throughout joint studies and other activities that are conducted with the think tanks in this region (Hungary, Czech Republic, and Slovakia).

TTX(Table Top Exercises)

In cooperation with the Heritage Foundation, Sasakawa Peace Foundation conducts Table Top Exercises to validate the research findings of the Japan-U.S. Study Group and others and simulate policymaking processes in order to identify new issues. In FY2022, TTX was held on ”Taiwan Contingency Scenario : Escalation from Low-Intensity Hybrid Warfare.” Click here for the deliverables of past TTX.

Open Forum

Second Webinar: “Problems with China’s Coast Guard Law and Japan’s Response” (video with English subtitles)

China enacted its Coast Guard Law on Jan. 23, 2021, which took effect on Feb. 1. Japanese media reports pointed out that the China Coast Guard was now authorized to use weapons and that China had put in place domestic laws to serve as the legal basis for actions not allowed under international law. However, the problems with this Coast Guard Law have not really been clarified. Moreover, the discussion on how Japan should respond has only just begun. This open forum analyzed the Coast Guard Law from the standpoints of operations and international law and discussed the issues with this law and Japan’s response.

Date: Sept. 9, 2021 (Thursday)
