On the 15th, the Japan Innovation Party (Ishin) held an executive meeting where they confirmed the continuation of Yoshimura Hirofumi's leadership as the head of the party. This decision came after discussions related to whether to conduct a representative election following a significant electoral event; with many party members expressing that holding an election would imply a vote of no confidence in Yoshimura. An electronic vote held during the meeting revealed that a majority, 619 votes against and 102 in favor, decided not to proceed with an election.

Ishin saw a modest gain in the recent House of Representatives election, securing 36 seats, which is two more than what they held prior to the election but short of their aspirational target of 38 seats. This context influenced the party’s decision as they seek stability and continuity in leadership at this time, particularly given the challenging electoral goals they set out.

Furthermore, during the executive meeting, it was reported that Prime Minister Sanae Takaichi, who also leads the Liberal Democratic Party, expressed interest in cabinet cooperation with Ishin, especially with impending cabinet reshuffles expected this autumn. This proposal was met with no objections from the party members, indicating a readiness to engage in collaborative governance moving forward.
