Japanese Prime Minister Sanae Takaichi on Monday publicly thanked U.S. President Donald Trump for his support after her ruling coalition secured a landslide victory in the lower house over the weekend. In a social media post, Takaichi said she is "sincerely grateful to President Donald J. Trump for his warm words," and announced plans to travel to the White House in the spring.
In the same post she highlighted the strategic focus of her administration, stating, "I look forward to visiting the White House this spring and to continuing our work together to further strengthen the Japan–U.S. Alliance." She added, "The potential of our Alliance is LIMITLESS."
The election outcome came as the coalition formed by the Liberal Democratic Party and the Japan Innovation Party won a supermajority in Japan's lower house on Sunday. That parliamentary strength, the prime minister's office said, opens a route for Takaichi to advance her fiscal agenda. The supermajority also creates the procedural ability to bypass the upper house, where her parties do not hold a majority.
President Trump had offered his endorsement of Takaichi prior to voting and sent his congratulations on Sunday evening after her victory was confirmed.
Takaichi, Japan's first female prime minister, has advanced a more assertive foreign and security stance. Her stated priorities include increased defence spending and a tougher posture toward China. Strengthening the relationship with the United States has been identified by her administration as a central element of that agenda.
She previously met with President Trump shortly after taking office in October 2025, and Monday's public remarks reaffirmed the administration's intention to maintain close coordination with Washington.
Taken together, the electoral outcome and Takaichi's stated priorities set the immediate political context: a strengthened ruling coalition with the parliamentary tools to pursue fiscal measures and a clearer mandate to press forward on defence and bilateral security cooperation with the United States. How those priorities translate into concrete legislation and policy measures will depend on the coalition's ability to sustain its parliamentary position and on subsequent engagements with international partners.
