Japan’s Choices in the Era of Inter-Regime Competition

The RCAST Open Laboratory for Emergence Strategies is independently conducting the research project on "Japan’s Choices in the Era of Inter-Regime Competition: Policy Proposals and Information Sharing based on Long-term Scenario Planning in Search for the Proactive Role in the Emergence of the New International Order” which is supported by the research grants for diplomacy and security of the Ministry of Foreign Affairs of Japan starting from the fiscal year 2020.

Today, our world has entered an era of significant change, notably with the rise of authoritarian states like China and Russia, changes within the existing order centered on the United States and the European states, ideological and geopolitical challenges in the Middle East, as well as developments in new and emerging technologies. The Project purports to serve as a platform to work with experts to provide analysis and policy recommendations to promote Japan’s involvement in forming the new international order.


Working Group 1 on China and the Challenge of Authoritarian Regimes

With the rise of China and growing influence of Russia, authoritarian states are strengthening their presence, raising concerns over the impact on the international order. This working group aims to examine the ideological background and the characteristics of the regimes, as well as their relations with regional states. 

Working Group 2 on Middle Eastern and Islamic Alternatives

The circumstances in the Middle East and the Islamic world has become growingly complex with: the spread of extremism such as the “Islamic State,” tribal, regional, and ethnic conflicts; restructuring of the regional order led by Iran and Turkey; as well as the axis centering on Israel and Saudi Arabia. This working group aims to assess the new order in the Middle East and the Islamic world. 

Working Group 3 on the US and Destabilization of the Established Order

The “Trump phenomena” in the United States, the United Kingdom’s withdrawal from the European Union, as well as the rise of anti-liberal forces within the European Union are pointing to changes in the international order. This working group aims to examine the ideological underpinnings and divisions within the developed states, and their impact on alliances.

Working Group 4 on the Emerging Issues in Security Studies

The security environment is significantly changing due to the rise of new and emerging technologies such as information communication technologies and artificial intelligence. In addition, there is a growing need to examine the new security issues relating to information and knowledge that go beyond the conventional forms of traditional security concerning war and peace, and non-traditional security issues such as climate change and infectious diseases. This working group aims to look at the new trends and their impact on current security.

Working Group 5 on Indo-Pacific Transport Security

The Indo-Pacific security environment is experiencing new uncertainties due to geopolitical conflicts, military modernization, crime and terrorism, natural disasters, and pandemics. Such issues not only threaten the security of states and their citizens, but also domestic and international transportation that is vital to trade, supply-chains, and exchange. This study group aims to analyze the impact of regional security risks in the Indo-Pacific on the transport sector, as well as specific transport security issues in the region. 

Sub-Working Group 1 on Satellite Imagery Analysis Project

This subgroup within the “Working Group 4 on the Emerging Issues in Security Studies” aims to conduct assessments of the international security developments through high-resolution satellite images provided by Maxar Technologies.

Sub-Working Group 2 on Tabletop Exercises

This subgroup within the “Working Group 5 on Indo-Pacific Transport Security” aims to better understand the Indo-Pacific security developments and their implications through tabletop exercises (TTX).

Sub-Working Group 3 on Japan-U.S. Security Treaty History

This subgroup within the "Working Group 3 on the US and Destabilization of the Established Order" aims to deepen the understanding of the history of the Japan-US alliance by collecting and organizing important documents related to the Japan-US Security Treaty and publishing them in the form of an online database.
