Japan's LDP Faces Uncertain Future as Takaichi Seeks to Become First Female Prime Minister

Strategic Insights

— 2 min read

The Japanese legislature, the Diet, is set to meet for an extraordinary session to vote for the next prime minister. The vote on Tuesday follows the collapse of a 26-year-old partnership between the Liberal Democratic Party (LDP) and the smaller Komeito party after Sanae Takaichi took the helm of the LDP. The LDP has been the dominant force in Japanese politics since the 1950s but has lost its majority in both legislative houses after failing to address a series of problems, including a major corruption scandal and Japan's cost-of-living crisis. Sanae Takaichi, the LDP's new leader, is a foreign policy hawk who wants to strengthen Japan's military and has conservative views on same-sex marriage. However, her election as LDP leader on October 4 was met with disagreement from the Komeito party over corporate donations, which led to the collapse of the partnership.

Key Takeaways:

  • The LDP's 26-year-old partnership with the Komeito party collapsed after Sanae Takaichi took the helm of the LDP due to disagreements over corporate donations.
  • Takaichi, as the leader of the LDP, needs at least 233 seats to secure a majority in the lower house of the Diet, which she currently has 196 seats.
  • Takaichi's platform includes aggressive fiscal expansion to resolve Japan's economic problems, strengthening Japan's military, and conservative views on same-sex marriage.
  • The LDP's potential challenger, Yuichiro Tamaki, leader of the Democratic Party for the People, could secure a majority if it cooperated with the centre-left Constitutional Democratic Party of Japan and the Japan Innovation Party.
  • The Japan Innovation Party is likely to form a coalition with the LDP due to their shared views on major policy concerns like the United States, China, Taiwan, immigration, and the future of the imperial family.
  • Takaichi will be a much weaker prime minister than her predecessors and may not survive more than a year in office due to external factors like the US relationship and internal factors like the direction of the economy.
