A by-election for the Kyoto-3rd seat in the Japanese House of Representatives was held on 24 April 2016, coinciding with the by-election in Hokkaido. The seat became vacant after sitting member Kensuke Miyazaki resigned on 12 February 2016 in the midst of an extramarital affair scandal. Miyazaki, a member of the Liberal Democratic Party, served the district from 2012. He defeated Democratic Party of Japan MP Kenta Izumi by slim margins in the 2012 (0.1%) and 2014 (2.7%) elections. Izumi managed to wrest back his old seat by a landslide, eclipsing his nearest rival by 45 percentage points.
