Japan's House of Representatives, dissolved in late January 2026 for a snap election won decisively by the Liberal Democratic Party with a supermajority exceeding 300 seats, now operates under a full four-year term extending through 2030 absent extraordinary triggers. The ruling coalition's strengthened position, reinforced by the April passage of the FY2026 budget and the absence of no-confidence motions or internal factional challenges through mid-May, has reduced incentives for another dissolution this calendar year. With the Diet focused on legislative continuity rather than early campaigning, traders assign high probability to the lower house completing its mandate without interruption.
