Japan’s Ruling Party Elects Sanae Takaichi as New Leader, Poised to Become First Female Prime Minister

Tokyo, October 4, 2025 — Japan’s long‑dominant Liberal Democratic Party (LDP) elected Sanae Takaichi as its new leader on Saturday, placing her on track to become the country’s first female prime minister.


Power shift amid party crisis

Takaichi, 64, defeated Agriculture Minister Shinjiro Koizumi in a runoff vote after an inconclusive first round. In doing so, she replaces outgoing Prime Minister Shigeru Ishiba, who announced his stepping down following mounting pressure within the LDP and declining public support.

The vote involved 295 LDP parliamentarians and about one million dues-paying party members—a process representing only about 1 % of Japan’s electorate. With party discipline strong and the opposition fragmented, Takaichi is widely expected to be confirmed by the Diet (parliament) in mid‑October as Japan’s prime minister.


A historic, but complex milestone

Takaichi’s election marks a significant symbolic milestone: she becomes the first woman to lead the LDP in its 70-year history, and likely the first female head of government in Japan.At the same time, critics caution that her policy record and ideological stances complicate the narrative of progress in gender equality.

A staunch conservative and self-described admirer of former British Prime Minister Margaret Thatcher, Takaichi is aligned with the LDP’s right wing. She has strong ties to the legacy of Shinzo Abe, whose national-security, constitutional reform, and assertive foreign‑policy agenda she supports.

Her election victory may reveal more about the LDP’s current strategic turning point than a broader push for social reform. Analysts note that she has historically resisted certain gender-equality measures—such as allowing dual surnames for married couples or backing female succession to the imperial line.


Policy priorities and challenges ahead

Economic stimulus & “crisis management investment”

Takaichi has pushed for robust fiscal measures and “crisis management investment” across sectors such as artificial intelligence, semiconductors, energy, and defense. Her approach echoes the “Abenomics” era’s reliance on stimulus but comes with tighter caveats about ensuring fiscal discipline as Japan grapples with high public debt. Critics warn that expansive spending might unsettle investor confidence and put strain on the yen.

Foreign policy and regional relations

Takaichi’s hawkish views on China and her strong nationalist leanings could complicate diplomatic relations in East Asia. She is a regular visitor to the controversial Yasukuni Shrine, a sensitivity in Japan’s relations with South Korea and China. She also supports expanding ties with Taiwan and strengthening Japan’s defense posture.

Her victory may prompt renewed debates over constitutional reform—especially Article 9, the pacifist clause—though she is expected to proceed cautiously due to the divided views within her party.

Political headwinds & public trust

Takaichi inherits a party battered by electoral losses, public disillusionment, and scandal over political funding. The LDP has lost its majority in both houses of parliament, weakening its ability to drive legislation without cross-party cooperation.

To govern effectively, she will likely need to build or expand coalitions with centrist and moderate opposition parties. Early tests include managing inflation, food and energy security, and domestic challenges such as population decline and labor shortages.

Takaichi has acknowledged the weight of expectations. At the announcement, she thanked supporters but stressed the “mountain of challenges” ahead, calling for unity within the party.


Looking ahead: confirmation and what to watch

A parliamentary vote is tentatively scheduled for mid‑October (around October 15) to formally appoint Japan’s next prime minister. Meanwhile, Takaichi’s leadership will begin under the glare of high expectations, difficult internal dynamics, and complex regional pressures.

Key indicators to watch:

  • Whether she secures sufficient support among opposition parties to pass major legislation
  • Moves on constitutional reform, defense, and regional diplomacy
  • Responses from China, South Korea, and the United States
  • Public opinion and the stability of the LDP going into the next national election
