Liberal Democratic Party (Yamatai)

The Liberal Democratic Party (自由民主党) is a far-right, conservative and nationalistic political party in Yamatai. It is considered one of the most right-wing parties in Yamatai, and borders on ultranationalistic. The current LDP has ties to ultranationalist organisations such as GYO and the Yamatai Revitalisation Movement, the largest ultranationalist lobby in Yamatai.

The current Liberal Democratic Party has its roots in the 1998 merger between the original LDP and the Radiant Sun Party. The original LDP was a centre-right party founded in 1949 and was one of the first political parties formed in post-war Yamatai, and it was primarily an ally of the Yamatai Restoration Party between 1960 and 1990. In 1980, the Radiant Sun Party was formed by a group of right-wing nationalist lawmakers and Gikai members led by then-Governor of Heian Aso Shinzo. In 1998, the LDP executed a merger with the Radiant Sun Party in reaction to the YRP's loss to the leftist Social Democratic Party of Yamatai in that year's general election. Initially intended to form a new right-wing political bloc separate from the YRP, a power struggle within the post-merger LDP resulted in most of the original LDP leadership and members migrating to the newly-formed National Action Party, leaving the former Radiant Sun leaders in control of the new LDP.

Despite the shift in political makeup of the LDP, it remains one of the strongest allies of the YRP and is part of its governing coalition. The current leader of the LDP is Sugamo Yoshihide, who took over in 2020 after the previous leader contracted irritable bowel syndrome and went into early retirement. Some analysts believe that the LDP is mainly a puppet party of the YRP, and is used as an easily deniable platform for the YRP to promote their more far-right views while maintaining a more moderate and centre-right image for the main YRP.
