Prefectural elections for the Tokyo Metropolitan Assembly was held on 23 June 2013, one month before 2013 Japanese House of Councillors election.[1]
The Liberal Democratic Party took majority control of the assembly from the Democratic Party of Japan after Prime Minister Shinzo Abe stated that the election had to be won "at any cost" in order to set the stage for an LDP victory in the House of Councillors election.[2] Abe used the victory to claim popular backing for his "Abenomics" economic policies.[3] The Japan Restoration Party performed poorly after controversial remarks by its leader Toru Hashimoto regarding comfort women, while Your Party made gains in the assembly after distancing itself from the JRP.[4]
