Former defense minister Shigeru Ishiba will become Japan’s new prime minister after winning his party’s leadership contest on Friday, following a crowded race that ended in a runoff vote.

The 67-year-old takes control of the long-ruling, scandal-plagued Liberal Democratic Party (LDP) and will assume command of the world’s fourth-largest economy once parliament convenes in October, due to his party’s majority in the lower house.

He was one of nine candidates and beat economic security minister Sanae Takaichi – who was vying to become Japan’s first woman leader – in the runoff, with 215 votes to 194. A third frontrunner who didn’t make the final cut was Shinjiro Koizumi, the US-educated, charismatic son of popular former prime minister Junichiro Koizumi.

It was Ishiba’s fifth attempt to lead the party, a conservative political machine that has ruled Japan almost continuously since the party’s founding in 1955.

In a political culture that prizes conformity, Ishiba has long been something of an outlier, willing to criticize and go against his own party. That willingness to speak out made him powerful enemies within the LDP but endeared him to more grassroots members and the public.

He sits on the more progressive wing of the conservative party. His political acumen and experience in domestic and foreign policy likely led to him securing the top job.

Following the vote, Ishiba said the LDP could now be “reborn and regain the trust of the people.”

“I will believe in the people, speak the truth with courage and sincerity, and I will do my utmost to make this country a safe and secure place where everyone can live with a smile on their faces once again.”
