Tokyo: Japan’s ruling Liberal Democratic Party (LDP) is bracing for a fierce leadership battle following Prime Minister Shigeru Ishiba’s decision to resign after a string of electoral defeats. With the party weakened in parliament and facing growing public discontent, two prominent figures Shinjiro Koizumi and Yoshimasa Hayashi have formally launched their campaigns, setting the stage for a contest that could reshape Japan’s political future.
Shinjiro Koizumi, the youthful Minister of Agriculture, Forestry and Fisheries and son of former Prime Minister Junichiro Koizumi, confirmed his candidacy on Tuesday. Koizumi, who has recently gained public visibility for his efforts to stabilize rice prices, is seen as a politician with generational appeal and reformist instincts. His campaign will be backed by Finance Minister Katsunobu Kato, signaling support from influential figures within the LDP establishment.
Also entering the race is Yoshimasa Hayashi, the Chief Cabinet Secretary and the government’s most senior spokesperson. Hayashi announced his candidacy on social media, vowing to lead “a new administration that balances stability and growth.” Known for his experience in diplomacy and governance, Hayashi is expected to emphasize steady leadership at a time of economic and political turbulence. He is preparing for a formal campaign launch with a press conference later this week.
The race, however, is far from a two-person contest. Former Foreign Minister Toshimitsu Motegi and former Economic Security Minister Takayuki Kobayashi are also vying for the top job. In addition, former Internal Affairs Minister Sanae Takaichi is widely expected to run, a move that would make her a potential trailblazer as Japan’s first female prime minister. Takaichi has long championed aggressive economic stimulus and is likely to position herself as a conservative but innovative choice for leadership.
Prime Minister Ishiba’s resignation has cast a shadow over the party. He announced earlier this month that he would step down, acknowledging responsibility for the LDP’s losses in both the lower and upper houses of parliament. These setbacks have eroded the LDP’s once iron-clad dominance and left its coalition with Komeito without a majority, raising doubts about the government’s stability.
The leadership race carries high stakes. Japan’s next leader will inherit the challenge of restoring confidence in the LDP while tackling pressing domestic concerns such as inflation, the rising cost of living, and stagnant wages. Koizumi’s reform-oriented image may attract younger voters, while Hayashi’s reputation for calm competence could reassure the party’s traditional base. Takaichi, if she enters, would bring historic momentum to the contest, appealing to those seeking greater representation of women in Japan’s political leadership.
The party will hold its leadership vote in early October, with the winner set to become Japan’s next prime minister. For the LDP, this contest is not only about choosing a new leader but also about proving it can adapt to changing times and regain the trust of the electorate. The coming weeks are expected to be marked by intense campaigning, shifting alliances among party factions, and a spotlight on the candidates’ ability to balance reform with stability.
In a nation grappling with economic pressure and regional security challenges, the outcome of this leadership battle will shape Japan’s political trajectory for years to come.
