Japan’s Political Landscape Shifts as LDP and JIP Form Coalition
Sanae Takaichi is poised to become Japan’s first woman prime minister after her Liberal Democratic Party (LDP) struck a coalition deal with the Japan Innovation Party (JIP). The agreement, expected to be formally signed on Monday, comes after the LDP’s 26-year alliance with Komeito collapsed.
Key Takeaways
- Sanae Takaichi expected to become Japan’s first female PM in Tuesday’s parliamentary vote
- LDP-JIP coalition falls just short of majority with 231 combined seats
- Major policy concessions include zero food tax and political donation reforms
Coformation Details
The newly elected LDP leader, Sanae Takaichi, and JIP chief Hirofumi Yoshimura will officially sign the coalition pact on Monday. The JIP will support the LDP from outside the Cabinet rather than taking ministerial positions.
Political Mathematics
Even with JIP’s backing, the coalition would control 231 seats in the 465-member House of Representatives – just two seats short of an outright majority. The LDP holds 196 seats while JIP has 35.
Policy Breakthroughs
Senior members from both parties agreed on key concessions including:
- Reduction of consumption tax on food to zero
- Ban on corporate and organizational donations by September 2027
- Reduction of seats in Japan’s National Diet
Yoshimura described the Diet seat reduction as a “nonnegotiable condition” for cooperation. The parties plan to introduce related legislation during the extraordinary Diet session starting Tuesday.
Cooperation Framework
While Takaichi invited JIP to join the Cabinet, the party declined, choosing instead to support from outside while monitoring policy implementation. A joint consultative body will coordinate policy matters between the two sides.
Yoshimura emphasized that JIP’s participation focuses on achieving policy outcomes rather than pursuing Cabinet positions. The party will be included in pre-legislative discussions on government bills.
Opposition Landscape
The main opposition Constitutional Democratic Party of Japan (CDPJ) plans to nominate its leader, former Prime Minister Yoshihiko Noda, for the premiership. However, Takaichi is expected to win with support from her party and allies.
Separately, Democratic Party for the People (DPP) leader Yuichiro Tamaki expressed openness to working with Takaichi on aligned policy priorities.
