TOKYO — Japan’s ruling Liberal Democratic Party (LDP) on Saturday elected Sanae Takaichi, a hardline conservative, as its new leader — putting her on track to become Japan’s first-ever female prime minister.
For most of Japan’s post-war history, the LDP presidency has virtually guaranteed the premiership since the party or its coalition partners hold majorities in parliament.
Although the LDP-led coalition lost its majority in both houses over the past year, it remains the largest party in the lower house, giving Takaichi a near-certain path to leadership when lawmakers vote in mid-October.

Parliament Vote Expected Mid-October
Under Japan’s parliamentary system, both houses of the Diet — the lower and upper chambers — vote to select the prime minister. Lawmakers can nominate any sitting member, though traditionally, party leaders are put forward.
A simple majority in the first round of voting secures victory. If no candidate crosses that threshold, a runoff is held between the top two contenders.
If the two houses disagree, the lower house’s choice prevails — a precedent set in 2008, when the LDP’s candidate was chosen over the opposition’s pick.
LDP’s Political Legacy and Alliances
The LDP, which has dominated Japanese politics for decades, has a long history of coalition-building to maintain power. In 1994, it formed a three-party alliance with its traditional rival, the Japan Socialist Party, and a smaller faction to return to power, electing socialist leader Tomiichi Murayama as prime minister.
Takaichi’s election continues the LDP’s trend of strong internal continuity while also marking a historic first for women in Japan’s political hierarchy.
Transition and Next Steps
Once the parliamentary vote confirms her position, current Prime Minister Shigeru Ishiba will step down, and Takaichi will move swiftly to form her cabinet.
The new government lineup will then be formally approved by Emperor Naruhito, in keeping with Japanese constitutional tradition.
Takaichi’s first major diplomatic task is expected to be attending the ASEAN summit in Malaysia, followed by hosting U.S. President Donald Trump in Tokyo later this month — key engagements that will set the tone for her leadership on the global stage.
Her ascension symbolizes a new era in Japanese politics, blending conservative policy instincts with a historic breakthrough for gender representation in national leadership.
