TOKYO — Japan’s political landscape has been thrown into disarray following the dissolution of the long-standing coalition between the ruling Liberal Democratic Party (LDP) and the centrist Komeito party. Amid this crisis, Sanae Takaichi, the newly elected LDP President, is urgently seeking a lifeline by engaging in cooperative talks with the second-largest opposition group, Nippon Ishin no Kai (Japan Innovation Party, or Ishin). A successful alliance could secure her selection as Japan's next prime minister, potentially making her the country's first female leader.

Ishin Holds the Key as Coalition Collapses 

Takaichi's chances of securing the premiership—a title effectively decided by a vote in the powerful Lower House of the Diet—were significantly clouded after the Buddhist-backed Komeito announced its withdrawal from the government. Komeito cited discomfort with Takaichi's ultra-conservative political stance and the LDP's failure to fully address recent money scandals.

Faced with a minority government, the LDP has turned to the conservative, Osaka-based Ishin party for support. On the evening of October 15, Takaichi met with Hirofumi Yoshimura, the Co-Leader of Nippon Ishin no Kai, to discuss potential cooperation. The talks reportedly made substantial progress, with both sides agreeing to commence detailed policy negotiations starting October 16.

"The basic policies of both parties are largely in agreement," Takaichi told reporters after the meeting. She specifically addressed Ishin’s long-cherished ambition: the Osaka Vice-Capital Plan (or "Secondary Capital" concept), stating, "We aim to finalize it through inter-party discussions and target submission [of the bill] to next year's ordinary Diet session."

Policy Alignment Paves the Way for Prime Minister Bid 

The Osaka Vice-Capital concept is a core demand for Ishin, a party that advocates for greater decentralization. Their proposal seeks to designate the Osaka area as a backup capital capable of substituting for Tokyo in the event of a major disaster, granting it greater fiscal and deregulatory powers.

Yoshimura's response regarding support for Takaichi in the upcoming prime minister designation vote was markedly positive. He indicated that if a consensus is reached in the policy discussions, his party would likely back the LDP leader.

Ishin currently holds 35 seats in the House of Representatives. When combined with the LDP's 196 seats, the total reaches 231 seats. While this is two short of the 233 seats required for an absolute majority in the 465-seat Lower House, it brings Takaichi significantly closer to winning the first round or, at the very least, prevailing in the inevitable runoff.

Opposition Unity Falters Against LDP-Ishin Strength 

The prime minister designation process involves separate votes in the Lower and Upper Houses. If the results differ, the decision of the Lower House ultimately prevails, making a Lower House majority critical.

Meanwhile, the primary opposition, the Constitutional Democratic Party of Japan (CDP, 148 seats), has been attempting to coalesce the opposition around Yuichiro Tamaki, the popular leader of the Democratic Party for the People (DPFP, 27 seats). However, even if the CDP and DPFP were to fully unite, their combined strength of 175 seats would still be significantly fewer than the potential LDP-Ishin bloc. This political fragmentation among the opposition further strengthens Takaichi's hand.

Political analysts suggest that the LDP's cooperation with Ishin is a decisive factor. With the support of Nippon Ishin no Kai, Takaichi's chances of being elected prime minister in the Diet vote—expected to take place later in October—are now considered substantially higher, marking a key pivot point in Japan's political future.
