House of Councillors elections were held in Japan on 21 July 2019 to elect 124 of the 245 members of the House of Councillors, the upper house of the then 710-member bicameral National Diet, for a term of six years.

74 members were elected by single non-transferable vote (SNTV)/First-past-the-post (FPTP) voting in 45 multi- and single-member prefectural electoral districts. The nationwide district elected 50 members by D'Hondt proportional representation with optionally open lists, the previous most open list system was modified in 2018 to give parties the option to prioritize certain candidates over the voters' preferences in the proportional election.[1][2]

The election saw Prime Minister Shinzo Abe's ruling coalition lose the two-thirds majority needed to enact constitutional reform.[3][4] The Liberal Democratic Party also lost its majority in the House of Councillors, but the LDP maintained control of the House of Councillors with its junior coalition partner Komeito.
