The Iwate at-large district (岩手県選挙区, Iwate-ken senkyo-ku) is a constituency of the House of Councillors in the Diet of Japan. It consists of Iwate Prefecture and elects two Councilors, one every three years, making it one of the decisive single-member districts. Ichirō Ozawa came from the prefecture, and as a result, it is much more markedly competitive than many other rural, 2 seat districts. In fact, it was represented by two opposition members until 2022, when Hirose defeated CDP Councilor Eiji Kidoguchi to return it to split control. Kidoguchi defeated other opposition parties to win it back in a 2024 by-election following Hirose's resignation. It is also one of the districts where the opposition have been most consolidated; the last time multiple major party opposition members ran was 2013. The last LDP member to represent the district before Hirose was Motoo Shiina, who left the party in 1998.
