Sanae Takaichi Set to Become Japan’s First Female Prime Minister as Ishin Backs LDP Coalition

Japan is on the verge of making history as hardline conservative Sanae Takaichi is poised to become the country’s first female prime minister. Her rise comes after the Japan Innovation Party (Ishin), led by Osaka Governor Hirofumi Yoshimura, announced its readiness to back her leadership, forming a powerful alliance with the Liberal Democratic Party (LDP).

Yoshimura confirmed the agreement on Monday, stating, “I told Takaichi that we should move forward together.” He and Ishin’s co-leader Fumitake Fujita held discussions with party lawmakers earlier in the day before meeting Takaichi to finalize the partnership.

The LDP-Ishin coalition would control 231 seats in Japan’s lower house—just two short of a majority—but enough to secure Takaichi’s expected victory in Tuesday’s parliamentary vote. While Ishin will not initially take cabinet positions, the cooperation strengthens Takaichi’s path to governance following the collapse of the LDP’s 26-year alliance with Komeito.

Markets reacted swiftly to the anticipated coalition, with Japan’s Nikkei index surging nearly 3% and the yen weakening as investors bet on higher government spending and monetary easing. Analysts, including Nomura Securities’ Fumika Shimizu, noted that expectations for fiscal expansion under Takaichi’s leadership are fueling market optimism.

Known as a fiscal dove and security hawk, Takaichi advocates for increased spending, tax cuts, and constitutional reforms to strengthen Japan’s military. A frequent visitor to the Yasukuni Shrine, she supports boosting defense budgets and tightening immigration laws. However, Ishin’s preference for smaller government may temper her expansionary agenda.

If confirmed, Takaichi’s leadership marks a pivotal moment in Japanese politics—signaling both continuity and changeas Japan navigates economic challenges and evolving security dynamics in the region.
