日本維新會
Ishihara's new national party was expected to be formed with members of the right-wing Sunrise Party of Japan, which he had helped to set up in 2010. When announced by co-leaders Ishihara and SPJ chief Takeo Hiranuma on 13 November 2012, Sunrise Party incorporated all five members of SPJ. SP would look to form a coalition with other small parties including Osaka Mayor Toru Hashimoto's Japan Restoration Party (Nippon Ishin no Kai).
