General elections were held in Japan on 22 June 1980. They were the result of a vote of no confidence brought by the Japan Socialist Party (JSP) on 16 May regarding corruption and rises in public utility charges as reasons for the House of Representatives of Japan to withdraw its backing from the government.

The Japan Socialist Party was a socialist and progressive political party in Japan that existed from 1945 to 1996. The party was founded as the Social Democratic Party of Japan by members of several proletarian parties that existed before World War II, including the Social Mass Party, the Labour-Farmer Party, and the Japan Labour-Farmer Party. The party represented the Japanese left after the war, and was a major opponent of the right-wing Liberal Democratic Party.
