^ A: Komeito is a centrist party, but the right-wing LDP held a much larger number of seats.

The Liberal Democratic Party–Komeito coalition was an alliance in Japan between the Liberal Democratic Party (LDP) and Komeito. A coalition government between the parties has been established twice: the first from 5 October 1999 to 16 September 2009, and the second from 26 December 2012 to 10 October 2025, when Komeito announced their exit from the coalition.

History

The two parties formed a coalition in October 1999 during the premiership of Keizō Obuchi.[1]

The coalition was roundly defeated and lost power in the 2009 general election. In the general election on 16 December 2012, the LDP/Komeito coalition secured a supermajority and came back into government.[2][3]

In the 2024 general election, the LDP–Komeito coalition lost its majority for the first time since 2009. Although the LDP still remained the largest party, the coalition fell short of the 233 seats needed for a majority, securing only 215 and they formed the minority government.[4][5][6]

On 10 October 2025, Komeito chief representative Tetsuo Saito announced that it would leave the ruling coalition, over disagreements with new LDP president Sanae Takaichi.[7][8] Following Komeito's withdrawal, the LDP formed a coalition agreement with the Japan Innovation Party.[9]
