Japan is on track to get its first female prime minister after the leading conservative party elected Sanae Takaichi as its new leader.
Takaichi, who previously served as Japan’s economic security minister, won against Agriculture Minister Shinjiro Koizumi, the son of well-liked former Prime Minister Junichiro Koizumi, during a runoff in an internal election held by the ruling Liberal Democratic Party on Saturday.
Takaichi is replacing Prime Minister Shigeru Ishiba as the party looks to regain public support and stay in power.
Despite suffering major election losses, the Liberal Democratic Party remains by far the largest in the lower house and determines Japan’s leader because opposition groups are highly splintered.
Takaichi, a hard-line conservative who’s cited former British Prime Minister Margaret Thatcher as her hero, has called for strengthening Japan’s military, and taking a tougher stance against China and North Korea. She also opposes same-sex marriage and retains ties to nationalist groups.

Takaichi also faces a possible summit with President Donald Trump, who could demand that Japan increase its defense spending. A meeting is reportedly being planned for late October. Trump will travel to the Asia-Pacific Economic Cooperation summit in South Korea starting Oct. 31.
The LDP also needs help from the opposition, which it has long neglected. The party will likely look to expand its coalition with the moderate centrist Komeito with at least one of the key opposition parties, which are more centrist.
A parliamentary vote is expected in mid-October.
