Key View
- We expect Japan’s governing Liberal Democratic Party (LDP)-Komeito coalition to lose its majority in the Upper House election on July 20.
- The LDP’s loss of support reflects increasing dissatisfaction among voters, especially those of working age, with elevated inflation and social insurance costs.
- A loss of majority for the coalition would likely force Prime Minister Shigeru Ishiba to resign and thus delay progress on long-term economic and fiscal reforms.
We expect Japan’s ruling minority Liberal Democratic Party (LDP)-Komeito coalition to lose its majority in the upcoming Upper House election on July 20, 2025. We have revised our previous forecast of a narrow majority win following the LDP’s historically low seat count in the June 22 Tokyo Metropolitan Assembly election, which signalled weaker momentum for the party (see chart below).
The Liberal Democratic Party (LDP) of Japan faces the possibility of losing its majority, which could exacerbate existing policy weaknesses. Traditionally dominant, the LDP’s potential setback could lead to a fragmented political landscape, hindering decisive policy-making. This uncertainty is attributed to public dissatisfaction with handling economic reforms and social issues, such as an aging population.
Losing a majority would compel the LDP to form coalitions, likely resulting in watered-down policies as compromises with smaller parties become necessary. This could stall progress on critical issues like economic revitalization, technological innovation, and climate change initiatives. With Japan facing numerous challenges, the inability to implement strong policies may have lasting impacts on both domestic and international fronts.
Furthermore, a weakened LDP could embolden opposition parties, leading to increased political volatility. Such instability may deter investments and weaken Japan’s global standing. As the political landscape shifts, Japan’s future policy direction remains uncertain, emphasizing the need for strong leadership and visionary strategies to navigate forthcoming challenges.
