Japan After the Landslide: Takaichi’s Supermajority and the Trump Challenge
In a historic outcome, Japanese Prime Minister Takaichi Sanae has secured a political mandate unprecedented in modern Japanese politics. In the February 8 general election, the ruling Liberal Democratic Party (LDP) won 316 seats in the House of Representatives, Japan’s lower house, surpassing the previous postwar record of 300 seats set under Prime Minister Nakasone Yasuhiro in 1986. The result grants the LDP a rare single-party two-thirds supermajority, significantly strengthening Takaichi’s ability to advance her policy agenda.
Yet the scale of the victory brings not only expanded legislative freedom but also new strategic constraints. As Takaichi prepares for a summit with U.S. President Donald Trump for March 19, Japan must navigate growing expectations from Washington for increased defense burden-sharing while simultaneously managing a China that continues to maintain a hardline posture toward Tokyo.
