Since its establishment in 1955, the Liberal Democratic Party has dominated the political scene in Japan, but it is facing a decline in popularity today amid economic slowdown, declining birth rates, and rising social dissatisfaction.

Takaishi belongs to the right-wing faction within the party, and through her election, the party hopes to regain the support of the conservative base, which has recently been drawn to the far-right party Sansaito.

Sansaito has recently made a significant leap, raising the slogan "Japan First," and moved from one seat to 15 seats, contributing to the erosion of the Liberal Democratic Party's base, which lost its majority in both houses of parliament.

Takaishi acknowledged this crisis in a speech after her victory in the first round of voting, saying: "We received particularly harsh criticism from our core base - the conservatives and party members."

She added: "The Liberal Democratic Party must change for the present and future of Japan. We will always put the national interest first and govern the country with balance and responsibility."

Parliament is expected to ratify her appointment as Prime Minister on October 15th of this month.
