2017 Kibō no Tō leadership election

The Japanese conservative Kibō no Tō (the Party of Hope) held a leadership election on 10 November 2017. It was the party's first leadership election since its formation in September 2017, prior to the 2017 general election. The race was held to choose a co-leader to serve alongside party leader and founder Yuriko Koike.

Representative Yuichiro Tamaki beat fellow Kibō lawmaker Hiroshi Ogushi in the closed caucus election by a margin of 39 to 14. Tamaki was initially to lead the party in the Diet while Koike remained as a national leader. Four days after the leadership election, Koike resigned her leadership post, leaving Tamaki as the sole leader of the party.
