Japan could soon witness a historic shift in its political landscape as Sanae Takaichi, a veteran lawmaker and former economic security minister, positions herself as the leading contender to become the country’s next prime minister. If successful, she would be the first woman to lead the world’s fourth-largest economy, breaking through a glass ceiling that has long defined Japanese politics.

A Leadership Race with High Stakes

The sudden resignation of Prime Minister Shigeru Ishiba, who stepped down after taking responsibility for his party’s string of election defeats, has triggered a power vacuum within the ruling Liberal Democratic Party (LDP). Ishiba’s short tenure also left the LDP and its coalition partner Komeito without a majority in both houses of parliament, creating heightened uncertainty.

Two names have quickly risen to the forefront of speculation: Sanae Takaichi and Shinjiro Koizumi, the current agriculture minister and son of former prime minister Junichiro Koizumi. Neither has officially announced their candidacy, but political analysts expect both to join the leadership contest.

A Nikkei opinion poll conducted last month placed Takaichi narrowly ahead with 23% support, while Koizumi followed closely at 22%. This razor-thin margin highlights how competitive the race will be, and how divided the LDP’s support base remains.

Takaichi’s Candidacy: Policy, Power, and History

Sanae Takaichi is no stranger to high-stakes politics. In last year’s LDP leadership race, she led in the first round before ultimately losing in the runoff against Ishiba. Since then, she has distanced herself from Ishiba’s cabinet, rejecting offers to chair the LDP’s powerful General Council, signaling her independence and intent to chart her own path.

Known as an “apostle of Abenomics,” Takaichi aligns closely with the economic philosophy of the late Shinzo Abe. She has consistently pushed for aggressive fiscal spending, monetary easing, and structural reforms. Investors are paying close attention to her candidacy, particularly after her criticism of the Bank of Japan’s decision to end its negative interest rate policy in March 2024. While the BOJ has kept rates steady at 0.5%, Takaichi argued that raising rates was premature and could choke off recovery.

Beyond economics, she advocates constitutional reform, including revising Article 9 of Japan’s pacifist constitution to strengthen national defense—a position that resonates with Japan’s growing concerns over regional security threats.

Her candidacy also comes at a time when Japanese society may be more receptive to female leadership than ever before. Labor statistics show that about 85% of Japanese women aged 25 to 54 are in the workforce, compared with 78% in the United States, according to OECD data. Experts argue this rising participation underscores a cultural shift that could make her bid more viable than in past decades.

Koizumi’s Challenge: A Familiar Name, A Different Style

On the other side of the race, Shinjiro Koizumi carries the weight of a powerful political legacy. His father, Junichiro Koizumi, remains one of Japan’s most popular post-war leaders. Shinjiro rose to prominence by managing Japan’s agriculture sector during a period of surging rice prices, the steepest increase in over half a century.

Unlike Takaichi, Koizumi has avoided strong policy stances, which some analysts see as a strategic move. Jesper Koll, an expert director at Monex Group, noted that while Takaichi is admired for her strong and sometimes “radical” ideas, Koizumi is viewed as a safe, pragmatic candidate who could unify different factions within the LDP and build bridges with opposition parties.

This positioning could make him an appealing compromise choice, particularly for LDP old-guard members wary of major policy disruptions.

The Bigger Picture: Uncertainty Beyond the LDP

While the LDP is still the largest bloc in parliament, holding 196 of the 465 Lower House seats, its coalition with Komeito no longer commands a majority. This opens the possibility—though slim—that opposition parties could rally behind a single candidate and seize the premiership.

Nonetheless, most experts see an LDP-led candidate as the likely outcome, given the party’s organizational strength and influence. The question remains whether the LDP will lean toward Takaichi’s assertive, reformist agenda or Koizumi’s cautious, consensus-driven style.

A Turning Point for Japan

The stakes are high. Japan is grappling with a cost-of-living crisis, as food prices soar and households face mounting pressure. The recent trade deal with the U.S., imposing a 15% baseline tariff on Japanese exports—including cars—adds another layer of complexity to the country’s economic outlook.

As Japan navigates this uncertain future, the leadership race represents more than just a contest of personalities. It is a test of whether the country is ready to embrace a new era of political leadership, potentially led by its first female prime minister, or whether it will continue on a safer, more traditional path.

The coming weeks will be decisive in determining not only the LDP’s direction but the trajectory of Japan’s economy and its place on the global stage.
