Why Sanae Takaichi’s rise as Japan’s first female prime minister marks a nationalist turn in Tokyo politics

Japan’s nationalist glass ceiling moment

Japan elected Sanae Takaichi as its first female prime minister on Tuesday, marking a historic yet contentious moment in the country’s politics. The 64-year-old nationalist replaces Shigeru Ishiba, who resigned after election losses cost the ruling Liberal Democratic Party (LDP) its coalition majority in both chambers of parliament. Takaichi inherits a fragile government and must immediately navigate a visit from US President Donald Trump, scheduled for early next week, the Washington Post reported.

Trump visit looms as early test

Takaichi’s first challenge is her high-stakes meeting with Trump — a leader known for his unpredictability and transactional diplomacy. Japanese leaders usually visit Washington soon after taking office, but hosting Trump so quickly adds diplomatic pressure. The two are expected to discuss Japan’s $550 billion investment plan under the new US–Japan trade deal and the long-standing question of whether Tokyo will pay more to host US troops. Analysts say the visit could shape her early image at home and abroad.

A nationalist and Abe protégé

A protégé of former Prime Minister Shinzo Abe, Takaichi shares his conservative vision and close ties to Trump. She built her career on hawkish security views and nationalist policies that appeal to Japan’s right wing. Her slogan, “Japan First,” echoes Trump’s “America First” message and emphasizes protecting Japan’s economy and national interests. Takaichi has pledged to strengthen defence spending and take a hard line against China and North Korea, though that stance risks straining ties with South Korea.

Challenges at home and abroad

Despite her ideological confidence, Takaichi faces daunting political realities. The LDP now leads a minority government — a rare and weakened position for Japan’s dominant party. “You’re basically focused on your political survival,” said Jeffrey Hornung of RAND. “That sucks the air out of the alliance.” Experts warn that domestic instability could hinder her ability to negotiate firmly with Trump on troop-hosting costs or trade commitments.

A complicated view of history and gender

While her election breaks Japan’s highest glass ceiling, Takaichi is no feminist reformer. She has opposed allowing separate surnames for married couples and rejected changes that would let women from the imperial family’s maternal line ascend the throne. A self-described admirer of Margaret Thatcher, Takaichi has also drawn controversy for minimizing wartime atrocities and revising history textbooks to soften descriptions of Japan’s past aggression.

From policy wonk to prime minister

Takaichi’s career spans more than three decades. After working briefly in the US Congress in 1987, she entered Japanese politics in 1993 and rose steadily through the LDP ranks, serving in multiple cabinet roles. Supporters praise her as a tireless policy expert; critics see her as a hardliner moulded by Abe’s brand of conservative populism.

What her leadership means for Japan

Takaichi’s ascent signals a shift toward a more nationalist, security-focused Japan at a time of global volatility. Her ability to balance “Japan First” ambitions with the demands of the US alliance will define her tenure. As former Abe adviser Tomohiko Taniguchi put it: “Now is the time for her to develop her own timbre, her own calibre, as the top leader of the nation.”
