日本維新會
The Japan Restoration Party was formed in 2012 and was led by Tōru Hashimoto and Ishihara. In May 2014 Hashimoto and Ishihara announced that the party had agreed to split due to disagreement over a merger with another opposition party, the Unity Party. Ishihara's faction left the JRP to form the Party for Future Generations, which registered as a party on 1 August 2014. Takeo Hiranuma was chosen as the party's leader and he appointed Hiroshi Yamada as Secretary-General and Ishihara as chief advisor.
