Shintaro Ishihara
After long-term Governor Shintaro Ishihara suddenly resigned to return to national politics ahead of the then-looming next general election. A field of nine candidates emerged, with the front-runner being Naoki Inose, who had been vice-governor under Ishihara from 2007 to 2012, and then acting governor after Ishihara's abrupt resignation. Inose vowed to follow Ishihara's policies.
