**The lower house of Japan's National Diet was dissolved once in January 2026 for a February 8 snap election, after which Prime Minister Sanae Takaichi’s Liberal Democratic Party secured a historic supermajority of 316 seats.** This outcome has produced rare governing stability, with no procedural requirements, coalition pressures, or fiscal deadlines currently pointing toward another dissolution before year-end. Recent August developments, including routine cabinet adjustments and policy statements on defense and fiscal matters, show continuity rather than triggers for an early vote. The next lower-house election cycle would normally fall in 2030, and the upper house follows a separate staggered schedule. Traders therefore assign only a 6% probability to further dissolution in 2026, reflecting the absence of catalysts that historically prompt prime ministers to call snap polls.
