On December 18, 2018, the Japanese government issued its latest National Defense Program Guidelines (NDPG), marking another step in Japan’s defense planning and the readiness of the Japan Self-Defense Force (JSDF).

Corps analyses

Broadly, there are four key takeaways from the 2018 NDPG: (1) Nascent but notable push for readiness based on Japan’s expanded strategic frontiers under the auspices of the “Free and Open Indo-Pacific”, (2) the emerging concept of “offense is the best means of defense” to defend and deter against threats, (3) pursuit of readiness for multi-domain operations in the ground, maritime, air, cyber, outer space, and electromagnetic spectrums, and promoting jointness that coordinates operations in those domains, and (4) greater coordination and interoperability with the United States and to some extent with other likeminded states at the strategic, operational and tactical levels. The revised NDPG is certainly a new step in Japan’s accelerated efforts to sharpen and strengthen the JSDF’s readiness.

Yet, despite the notable developments over the past two decades, there are still some issues that constrain Japan from formulating the strategies and readiness to effectively deal with the fluid and uncertain security environment in the Indo-Pacific region, particularly with China’s increasingly assertive strategies and actions in the East and South China Seas and Taiwan Straits, North Korea’s continued bellicose behavior and military modernization, and also uncertainties over Russia’s strategies. Moreover, given the growing demands despite the political and economic constraints, there are still questions about how Japan’s defense planning and readiness will continue to advance in the years to come.

Center for Asian Studies
Accroche centre

Asia is a nerve center for multiple global economic, political and security challenges. The Center for Asian Studies provides documented expertise and a platform for discussion on Asian issues to accompany decision makers and explain and contextualize developments in the region for the sake of a larger public dialogue.

The Center's research is organized along two major axes: relations between Asia's major powers and the rest of the world; and internal economic and social dynamics of Asian countries. The Center's research focuses primarily on China, Japan, India, Taiwan and the Indo-Pacific, but also covers Southeast Asia, the Korean peninsula and the Pacific Islands. 

The Centre for Asian Studies maintains close institutional links with counterpart research institutes in Europe and Asia, and its researchers regularly carry out fieldwork in the region.

The Center organizes closed-door roundtables, expert-level seminars and a number of public events, including an Annual Conference, that welcome experts from Asia, Europe and the United States. The work of Center’s researchers, as well as that of their partners, is regularly published in the Center’s electronic journal Asie.Visions.

Space Security and Missile Defense : Japan's Quest for Autonomy and Indispensability

Date de publication
10 November 2026
Accroche

Seeking greater autonomy without loosening its alliance with the United States, Japan has steadily turned space into a pillar of its defense, building sovereign capabilities that also make it an indispensable partner, to Washington and beyond. This approach raises questions for Europe, whose ties with Japan are multiplying but which has yet to define what it can concretely bring to Tokyo, particularly in missile warning.

China’s Climate Leadership after Hormuz: How Should Europe Adjust?

Date de publication
26 October 2026
Accroche

The effective closure of the Strait of Hormuz in early 2026 offered an unplanned stress test of China’s approach to energy security, and China passed it far better than most expected. The episode demonstrated that the underlying risk of supply disruption is real, while validating a preference for resilience and resource security that has long underpinned Chinese energy and climate policy and has now been reinforced under the banner of building an “energy powerhouse.”

China as an ambivalent supporter of the WTO and the multilateral trading system

Amid rising trade tensions between Europe and China and broader uncertainty in the international rules-based trade regime, Beijing has worked to preserve and bolster the multilateral trading system while at the same time failing to reform the domestic policies that have served to undermine that same system.

Canada in the Indo-Pacific: Sustaining the Pivot, Partnering with France

Date de publication
02 November 2026
Accroche

Since the launch of Canada’s inaugural Indo-Pacific Strategy (IPS) in November 2022, Ottawa has moved—with notable but uneven momentum—from the margins of regional engagement to a position of growing strategic visibility. The Strategy, backed by an initial $2.3 billion five-year investment, reflects a long-overdue recognition: Canada is a Pacific nation whose prosperity and security are inextricably linked to the stability of the world’s most economically and strategically consequential region.
