General elections were held in Japan on 6 July 1986 to elect the 512 members of the House of Representatives, alongside elections for the House of Councillors. The result was a significant victory for the ruling Liberal Democratic Party (LDP), which gained 50 seats and an outright majority in the House. The LDP's 300 seats remains its joint-best general election result. Most opposition parties lost seat, the exceptions being the Japanese Communist Party (which remained at 26 seats) and the Socialist Democratic Federation, which gained one seat. The biggest losses were experienced by the Japan Socialist Party, which lost 27 seats. The Democratic Socialist Party saw a 12-seat loss, while Kōmeitō saw a loss of three seats and the New Liberal Club, which had been in coalition with the LDP, lost two seats.
