Which country's Liberal Democratic Party won an overwhelming majority in House of Representatives elections in February 2026?

In February 2026, Japan's Liberal Democratic Party (LDP) secured an overwhelming majority in the House of Representatives elections. This victory was a historic landslide, with the LDP winning a two-thirds supermajority of seats, marking the largest number of seats ever won by a single party in Japanese electoral history. The election was a snap election called by Prime Minister Sanae Takaichi, who had taken office in late 2025 following a period where the LDP had lost its majority in both houses of the Diet.

The Liberal Democratic Party has a long history of political dominance in Japan, having been in power almost continuously since its formation in 1955. While there have been brief periods where the LDP was out of power, such as from 1993-1996 and 2009-2012, its consistent electoral success has largely shaped modern Japanese history and government. The party is generally considered conservative, advocating for free-market economics, national security, and often working closely with business interests and maintaining a pro-U.S. foreign policy.

The House of Representatives is the more powerful lower house of Japan's National Diet, consisting of 465 members elected for a four-year term. The electoral system is a parallel system, combining 289 members elected from single-member constituencies by a first-past-the-post method, and 176 members elected through party-list proportional representation in 11 multi-member constituencies. An overwhelming majority, particularly a two-thirds supermajority, in the House of Representatives is highly significant, as it allows the ruling party to override vetoes on bills imposed by the House of Councillors, the upper house, and to push through its legislative agenda more easily.
