Sanae Takaichi Becomes Japan’s First Woman Prime Minister

On October 21, 2025, the Japanese National Diet nominated Sanae Takaichi to succeed Shigeru Ishiba, electing her as Japan's prime minister. Following the parliamentary confirmation, Emperor Naruhito officially appointed her during an investiture ceremony at the Tokyo Imperial Palace later that day. Her elevation marked the first time a woman had ever held the premiership since the country established a cabinet government structure in 1885, as well as the first time an official from Nara Prefecture attained the office.

Takaichi emerged as prime minister after consecutive runs for party leadership within the ruling Liberal Democratic Party. She had launched an unsuccessful campaign in 2021 before mounting a second bid in 2024, when she narrowly lost a runoff vote to Ishiba. Following Ishiba's resignation in September 2025, Takaichi stood for the post again, defeating agricultural minister Shinjiro Koizumi in the runoff round to become the first female president of the LDP. The political succession hit immediate turbulence when Komeito chose to depart from their twenty-six-year partnership with the LDP, prompting Takaichi to negotiate a replacement coalition pact with the Japan Innovation Party to secure the legislative votes required to take power.
