Secretary-General of the Liberal Democratic Party
The secretary-general of the Liberal Democratic Party is a high-ranking position within the Japanese conservative party, the Liberal Democratic Party. According to the LDP constitution, the secretary-general assists the party president in their duties.
As the LDP vice president is a largely ceremonial position, the secretary-general is de facto the second-most-powerful person in the party. The secretary-general is authorized to raise political donations and controls the party finances. The secretary-general holds the final authority over the list of LDP-backed candidates for the National Diet elections. The secretary-general oversees the LDP Diet Affairs Committee, responsible for steering party-supported bills through both chambers of the Diet, and appoints its chairman. The secretary-general also oversees key LDP organizations such as the personnel, treasury, information research and international bureaus.
The secretary-general is appointed by the president after the formal approval of the LDP General Council. The secretary-general is assisted by up to 30 deputy secretaries-general, appointed by the secretary-general with the approval of the General Council, one of whom is appointed as the acting secretary-general. The current secretary-general is Shun'ichi Suzuki, appointed on 7 October 2025.
