History

The two parties formed a coalition in October 1999.^[2]

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.^[3][4]

In the 2024 general election, the LDP-Komeito coalition lost their 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.^[5][6][7]
