Japan’s 2026 Defense White Paper Labels China as Greatest Strategic Challenge

POLICY WIRE — Tokyo, Japan — Japan’s recently released 610-page 2026 defense white paper underscores a continued and heightened strategic focus on China, labeling it as the “unprecedented and greatest strategic challenge” for the fourth consecutive year. This assessment, which dates back to 2014, reflects Tokyo’s persistent concerns over Beijing’s military activities and strategic ambitions in the region.

The white paper specifically cites China’s establishment of the East China Sea Air Defence Identification Zone in 2014 as a significant factor contributing to the risk of unintended incidents. Japanese Prime Minister Sanae Takaichi has maintained this trajectory, further accelerating Japan’s strategic reorientation towards countering perceived threats from China.

This strategic shift aligns with broader regional security dynamics, particularly as Beijing continues to expand its military presence and influence in the Asia-Pacific. The document highlights Japan’s efforts to bolster its defense capabilities and enhance its alliances, particularly with the United States, to address these evolving security challenges.
