In a significant political development, Japan’s ruling Liberal Democratic Party (LDP) has reached a preliminary agreement to form a coalition with the reformist Japan Innovation Party (JIP). This coalition could clear the way for Sanae Takaichi to become the country’s first female prime minister. Hirofumi Yoshimura, the governor of Osaka and leader of JIP, confirmed to Japanese media on Monday that an official announcement would be forthcoming to formalize the agreement.
Negotiations between the LDP and JIP culminated in a consensus during discussions held over the weekend. While this coalition does not secure a majority in Japan’s parliament, insiders suggest it will provide Takaichi with sufficient backing to secure her position in a parliamentary vote scheduled for Tuesday.
Under the proposed arrangement, the JIP will not take any cabinet positions but will lend its support to the LDP in advancing budgets and other essential legislation. The coalition will control 231 of the 465 seats in the lower house, along with 120 of the 248 seats in the upper house. This distribution enhances Takaichi’s chances of being elected, particularly as opposition parties have yet to unify around a rival candidate.
Furthermore, the LDP has expressed its commitment to support several of the JIP’s key policy priorities, including a proposed reduction in the number of MPs and the elevation of Osaka to the status of Japan’s “second capital.” Both parties share common ground on critical issues such as constitutional reform and the removal of a temporary petrol tax.
Following the announcement of the coalition agreement, shares in Tokyo saw a notable surge, reflecting optimism surrounding the potential policies of the Takaichi administration. The Nikkei 225 Average spiked by 2.9 percent during the morning session, achieving an all-time high, as investors speculate that Takaichi’s leadership will favor increased fiscal spending and positively influence the equity market.
With a background as a staunch conservative ally of the late Prime Minister Shinzo Abe, Takaichi has indicated that her administration will prioritize stimulating economic growth over rigid fiscal discipline, further fueling market expectations about her upcoming policies.
