Before the electoral reform of 1994, the area had been part of the multi-member Iwate 1st district that elected four Representatives by single non-transferable vote.
Iwate is the home of Ichirō Ozawa and like three of the prefecture's four post-reform districts, the 1st district had been represented by his parties from its creation to 2012: the New Frontier Party, the Liberal Party and the Democratic Party. In 2012, Ozawa and his followers split from the Democratic Party: 1st district representative Shina stayed with the Democrats, Ozawa's Tomorrow Party of Japan nominated Yōko Tasso, the wife of former representative and current Iwate governor Takuya Tasso; but Shina defended the district against Tasso and Liberal Democratic former prefectural assembly member Hinako Takahashi who won a proportional block seat.
