On 21 February 2020, Taro Yamamoto, the representative of the Reiwa Shinsengumi, announced that he would field Oishi in Osaka's 5th district for the next House of Representatives election. She finished third in the single-seat constituency behind Toru Kunishige of the New Komeito Party and Takeshi Miyamoto of the Japanese Communist Party, but in the proportional Kinki bloc, where there were multiple candidates, she ranked lowest out of 28 seats, at 28th place, and Reiwa Shinsengumi won one seat. However, Oishi, who had the highest sekihairitsu among the five people ranked first on the list, secured her seat and was elected for the first time. She is a member of the Budget Committee of the House of Representatives.

On December 18, 2022, she ran for the Reiwa Shinsengumi representative election in a joint campaign with Mari Kushibuchi, but lost to Taro Yamamoto. The following day, Yamamoto nominated Oishi and Kushibuchi as party co-representatives.
