The ongoing LDP leadership race has taken center stage in Japanese politics, with candidates emphasizing foreign defense policies. This leadership contest carries significant implications for Japan’s strategic posture amid growing regional tensions. The Liberal Democratic Party (LDP) began selecting its next leader in late September 2025. This choice is crucial as the leader will likely become Japan’s prime minister. Given the volatile security environment in East Asia, candidates are under pressure to present clear defense strategies aligned with Japan defense policy.
Three main contenders have emerged, each offering distinct views on foreign defense policies. They have outlined their plans for enhancing Japan’s self-defense capabilities and deepening alliances, particularly with the United States. Candidates also addressed North Korea’s missile threats and China’s military expansion in the East China Sea, both central issues influencing Japan defense policy in recent years.
The race’s timing is critical. Japan recently announced plans to boost defense spending, reaching nearly 2 percent of GDP. This move reflects growing concerns over regional stability and the need to modernize Japan’s military technology. As a result, the next LDP leader will face significant challenges in balancing domestic priorities and international expectations while maintaining a coherent Japan defense policy.
Experts note that the LDP leadership race will shape Japan’s defense trajectory for years to come. Political analyst Hiroshi Tanaka emphasized the importance of strong leadership in navigating complex security dynamics. “The chosen leader must manage relations with key allies while reassuring the Japanese public about national security,” he said.
Moreover, the candidates’ defense proposals reveal differing approaches to Japan’s pacifist constitution. Some favor more proactive defense measures, including revising Article 9, while others advocate for maintaining current restrictions but strengthening defense partnerships. The LDP membership and allied lawmakers are expected to vote in early October. The outcome will determine Japan’s policy direction during a pivotal period marked by North Korea’s missile tests and China’s assertiveness.
Looking ahead, the new leader must also address Japan’s role in multilateral security frameworks such as the Quad and AUKUS. Coordinating with allies will be vital to deter regional threats and ensure peace.
In conclusion, the LDP leadership race’s focus on foreign defense policies underscores the party’s awareness of emerging security challenges. The elected leader’s decisions will influence Japan’s diplomatic stance and defense posture amid an uncertain geopolitical landscape. As Japan navigates these complexities, strong and decisive leadership will remain essential.
