Ōita at-large district is a constituency in the House of Councillors of Japan, the upper house of the Diet of Japan (national legislature). It currently elects 2 members to the House of Councillors, 1 per election. It is unique among other Kyushu conservative kingdoms for its willingness to elect opposition members. Shinya Adachi held the districts 2022 seat from 2004, and Kiyoshi Adachi held the 2016 seat until his resignation in 2023, with Tadatomo Yoshida losing the by-election after by an extremely slim margin. This is possibly due to the presence of the city of Ōita, which has shown a willingness to support opposition candidates; it was historically also represented by a second Japan Socialist Party Councilor.
