Japan’s lower house of the Diet underwent dissolution in January 2026, followed by a February 8 snap election that delivered Prime Minister Sanae Takaichi’s Liberal Democratic Party a postwar-record supermajority of 316 seats. This outcome, secured just months into her tenure, has produced a stable governing majority unlikely to face pressure for another early poll before the next scheduled upper house contest in 2028. With legislative control consolidated and no immediate constitutional or political trigger for dissolution, traders assign only a 4.5% chance of further action in 2026. Late-year developments such as a sudden cabinet crisis, sharp decline in approval ratings, or unforeseen coalition fracture could still prompt reconsideration, though current institutional incentives favor continuity through year-end.
