2019 Osaka 12th district by-election

A by-election for the Osaka 12th district in the Japanese House of Representatives was held on 21 April 2019.[1] The by-election was called following the death of the incumbent member Tomokatsu Kitagawa, a member of the Liberal Democratic Party (LDP), from peritonitis on 26 December 2018. Kitagawa had served the district almost continuously since 2005 (except between 2009–12) and defended the seat by a narrow 4.4% margin in the 2017 election, making the seat a potential battleground. The by-election was held on the same day with the second round of the unified local elections and another House by-election for the Okinawa 3rd district.
