With the U.S.-Iran ceasefire unraveled, the war in the Middle East is once again threatening repercussions that is forcing Japan back to the drawing board about its economic and national security strategies.

In the short term, Prime Minister Sanae Takaichi must navigate the economic and diplomatic fallout that comes with renewed conflict in the Middle East.

Longer term, the war — and the changing nature of warfare — will inevitably influence how the Takaichi government will update Japan’s three core security documents: the National Security Strategy, National Defense Strategy and the Defense Buildup Program. Tokyo is currently reviewing these cornerstones of Japanese security policy, and the uncertain trajectory of the war will complicate the work of officials now shaping the administration’s future defense policies.
