Shigeru Ishiba’s unpopularity among LDP peers
Ishiba has a long history of being a vocal critic of the LDP, earning him a reputation as a turncoat among lawmakers. His most notable act of defiance came in 1993 when he supported a no-confidence vote against then-Prime Minister Kiichi Miyazawa. This move, along with his departure from the LDP to join a reformist faction led by Ichiro Ozawa, has left a lasting stain on his reputation within the party. Political science professor Yu Uchiyama notes that this history fuels perceptions of Ishiba as a "traitor" among senior politicians.
