Prime Minister Sanae Takaichi’s Liberal Democratic Party secured a supermajority exceeding 300 seats in the February 2026 snap election for the House of Representatives, extending the current term until at least 2030 barring extraordinary circumstances. Passage of the fiscal 2026 budget in early April and the absence of no-confidence motions or internal factional challenges through recent Diet sessions have further reduced any immediate incentive for another dissolution. Public debate over restricting the prime minister’s dissolution authority has surfaced following the January 2026 action, yet no procedural or political trigger has emerged to alter the current four-year cycle. This post-election stability forms the core basis for trader assessments that the lower house is unlikely to face dissolution before year-end.
