The Catalyst

Japan’s economic struggles and political instability created a perfect storm for this election. Ishiba’s approval ratings have suffered from a gift voucher scandal involving MPs and his inability to pass key legislation without opposition support.

Inside Forces

The LDP’s weakened position stems from its October 2024 House of Representatives election loss. Opposition parties like the CDP and Ishin no Kai have coordinated “opposition primaries” to avoid vote splitting, threatening the LDP’s control.

Power Dynamics

Ishiba’s minority government has struggled to implement policies, particularly on social security reforms. The right-wing populist party’s rise reflects voter frustration with traditional parties and growing nationalism.

Outside Impact

Voters are prioritizing economic relief amid rising costs and stagnant wages. The right-wing party’s focus on stricter immigration measures has resonated with some voters, though critics warn of xenophobic undertones.

Future Forces

Key post-election scenarios include:

• LDP retaining majority through coalition deals
• Opposition gaining control, forcing policy compromises
• Right-wing party gaining influence on immigration
