Before the electoral reform of the 1990s, the area had formed part of the five-member Osaka 5th district.
Between 2012 and 2021 the Representative from the district was Hodaka Maruyama. Initially a member of the Japan Restoration Party but later its successor party Ishin. In 2019, Maruyama was ejected from Ishin for comments he made under the influence of alcohol during a visit to the Kuril Islands and he joined the single-issue Anti-NHK party. Nobuhisa Itō, former Representative of the Osaka 11th district gained the seat back for Ishin in 2021.
In the 2026 general election, it was the only district in Osaka prefecture not won by the Ishin candidate.

Election results
Note: The decimal votes (anbunhyō, "proportional fractional votes") stem from the fact that in this case the given names Takashi and Yutaka are the reading of the same Chinese character 豊, and some voters apparently voted for 豊 without specifying a family name.
