In Japan's 51st House of Representatives election, held on the 8th, the Liberal Democratic Party (LDP) achieved a decisive victory, securing 310 seats—more than two-thirds of the total seats available. This victory comes on the heels of a major defeat in October 2024, when the party faced significant losses due to a scandal involving factional funding. The recent results signify a dramatic turnaround for the LDP, as they exceeded their previous total under Prime Minister Yasuhiro Nakasone in 1986, marking the first time a party has independently reached a two-thirds majority since World War II.

The election highlighted the struggles of opposition parties, particularly the Center Reform Alliance, which suffered a significant loss, failing to retain even half of the 167 seats it held prior to the elections. Many prominent members from the Constitutional Democratic Party, once considered a strong opposition force, lost their seats, indicating challenges for organized opposition in the legislature. The LDP's resurgence is also associated with the high approval ratings of Prime Minister Sanae Takaichi, who called for the election after more than a year and a half into the current legislative term.

The LDP's newfound majority allows it to push through legislation with greater ease. The implications of this victory mean that the LDP can now lower the threshold for passing constitutional amendments and potentially alter significant laws without the necessity of opposition approval. Nevertheless, the LDP's coalition partner, the Japan Innovation Party, faces challenges in securing an outright majority in the House of Councillors, which could complicate future governance efforts and legislative agendas with respect to matters such as constitutional reforms and other significant policy changes.
