A by-election for the Hokkaido-5th seat in the Japanese House of Representatives was held on 24 April 2016, coinciding with another by-election in Kyoto. The by-election was triggered by the death of the sitting member, former Speaker of the House and Foreign Minister Nobutaka Machimura from cerebral infarction in Osaka on 1 June 2015. Machimura, a member of the Liberal Democratic Party, was a long-serving representative for the district, holding the seat almost continuously between 1996 and 2015 (except for a brief period between 2009 and 2010). The seat has been considered safe for the LDP, with Machimura retaining it on a 14.1% margin in the 2014 general election.
