Craig Peacock argues Ishiba’s exit opens a high-stakes contest that will test whether the ruling party can restore stability, win back voters, and reassure global markets.

NEW DELHI, September 14, 2025 — Shigeru Ishiba’s resignation on September 7 has thrust Japan’s ruling Liberal Democratic Party (LDP) into a leadership battle that could redefine the country’s domestic trajectory and international standing. Writing on LinkedIn, Craig Peacock, Chief Advisor at Kujaku Japan Advisory, described the moment as a “turning point” for a party battered by electoral setbacks, rising living costs, and public disillusionment.

According to Peacock, the next prime minister will face formidable challenges: a fractured LDP, the loss of a majority in both houses of the Diet, and a sceptical electorate. The leadership vote, set for October 4, is not merely an internal affair, he argued, but “a test of whether the LDP can reinvent itself—or whether its rivalries will continue to erode its authority.”

Among the contenders, Toshimitsu Motegi is positioning himself as the pragmatic steady hand, promising incremental reform and fiscal caution. Sanae Takaichi, by contrast, is the unapologetic conservative, championing nationalist causes, higher defence spending, and pressure on the Bank of Japan. Shinjiro Koizumi, son of former PM Junichiro Koizumi, represents generational renewal with his reformist and environmentalist credentials, while Yoshimasa Hayashi brings diplomatic and technocratic gravitas. Takayuki Kobayashi, a younger conservative voice, is also in the race, though seen as a long shot.

Peacock cautioned that markets are already jittery and that foreign capitals—from Washington to Beijing—are closely watching Japan’s next move. “Whoever wins must bring more than survival instincts; they must show imagination, resilience, and a willingness to lead,” he wrote.

While Peacock sees Motegi as the likeliest frontrunner due to his appeal to party factions seeking stability, he noted that Takaichi’s grassroots energy, Koizumi’s charisma, and Hayashi’s competence all present viable alternatives.

“Japan cannot afford another revolving door of short-lived prime ministers,” Peacock concluded, stressing that October’s decision will shape both the fate of the LDP and Japan’s role in a turbulent world.

LDP Leadership Contenders at a Glance

Toshimitsu Motegi – The Pragmatist: Safe, steady, incremental reformer; reassures markets and party factions but risks looking like a caretaker.
Sanae Takaichi – The Conservative Firebrand: Nationalist, hawkish, and bold; energizes the right-wing base but polarizes moderates and investors.
Shinjiro Koizumi – The Heir of Renewal: Charismatic son of a former PM; appeals to younger voters but untested in top-tier governance.
Yoshimasa Hayashi – The Diplomat-Technocrat: Competent and internationally seasoned; respected, but may struggle to inspire the public.
Takayuki Kobayashi – The Wildcard: Younger conservative voice with economic security focus; limited backing, but could split the right.
