Representative Party Years served Notes
Kosuke Ito LDP 1996 – 2009 Lost re-election in the 2009 general election. He initially intended to run again as an independent in 2012, after the Liberal Democratic nomination was given to Masanobu Ogura. However, he withdrew his candidacy to support the candidacy of his son, Shunsuke Ito, who was running for the Japan Restoration Party.[5]
Mari Kushibuchi DPJ 2009 – 2012 Lost re-election in the 2012 general election. She was later chosen to replace Tarō Yamamoto in the Tokyo PR district after he resigned, since she had been the next highest Reiwa Shinsengumi member in the 2021 general election.[6][7] She currently serves in the seat as a co-representative with Akiko Oishi at the recommendation of Yamamoto.[8]
