Overview
- The party formally launched its leadership contest on Saturday, Aug. 22, with incumbent Yuichiro Tamaki and challenger Mikihiko Hashimoto both taking part in a Tokyo debate and joint news conference.
- Tamaki framed the three-year term as a period to prepare the party to implement policy and aims to make the party the largest opposition group in the upper house in 2028.
- Hashimoto called for remaking the party into a governing alternative to the Liberal Democratic Party, proposed separating the party leader from the prime-ministerial candidate, and said he would ask Tamaki to serve as that candidate if he became leader.
- The winner will be decided at an extraordinary party convention on Sept. 6 by a 159-point system shared among 53 Diet members, local assembly members, and party members and supporters, and candidates will campaign nationwide with street speeches and local debates until the vote.
- The contest will shape how the party positions itself against the Takaichi administration, influence candidate selection and policy focus ahead of the 2028 House of Councillors election, and affect how voters see the party’s ability to offer a clear alternative to the ruling coalition.
