Prime Minister Sanae Takaichi's election victory earlier this month has provided her with political capital to advance security and defense goals that were nearly unattainable a decade ago. She is preparing to update Japan's three key strategic documents ahead of schedule, discuss revisions to the three non-nuclear principles, and lay groundwork for amending the pacifist Constitution. Yet, unpredictable elements at home and abroad may hinder these efforts.
Prime Minister Sanae Takaichi's victory in the 2026 Lower House election has bolstered her position to pursue ambitious security and defense objectives. In her brief time in office, she has positioned herself to address both long-term and short-term priorities.
Key initiatives include accelerating updates to Japan's three main strategic documents by several years. Discussions are also underway to revise the country's three non-nuclear principles, alongside efforts to prepare for amendments to the pacifist Constitution. These aims were considered almost impossible just a decade earlier.
Takaichi has stated that she is prepared for the challenge of "taking on policies that divide the nation," acknowledging the divisive nature of these proposals amid domestic debates on the Constitution. Relevant factors include the U.S. military, the Defense Ministry, the Self-Defense Forces (SDF), U.S.-Japan relations, budgets, Donald Trump, espionage, and nuclear weapons.
Nevertheless, the prime minister must navigate carefully due to unpredictable domestic and international elements. Proceedings in the Diet and discussions on nuclear weapons could impact the realization of these goals.
