Prime Minister Sanae Takaichi dissolved Japan’s Lower House of the National Diet in January 2026, triggering a snap general election on February 8 that delivered the Liberal Democratic Party a historic two-thirds supermajority. This outcome, achieved through a short campaign focused on economic policy continuity and coalition realignment with the Japan Innovation Party, has produced a stable governing majority unlikely to face immediate electoral pressure. With the next scheduled upper house contest not until 2028 and no reported legislative gridlock or leadership challenges emerging since February, traders assign only a low implied probability to any additional Lower House dissolution before year-end. Recent reporting emphasizes the LDP’s strengthened position and absence of procedural triggers for further early polls.
