House of Councillors elections were held in Japan on July 11, 2010. In the previous elections in 2007 the Liberal Democratic Party (LDP) had lost its majority to the Democratic Party (DPJ), which managed to gain the largest margin since its formation in 1996. The House of Councillors is elected by halves to six-year terms. The seats up for election in 2010 were last contested in the 2004 election.
