The 47th general election of members of the House of Representatives(第47回衆議院議員総選挙,dai-yonjūnanakai Shūgiin giin sōsenkyo?) of Japan will be held on 14 December 2014. Voting will take place in all Representatives constituencies of Japan including proportional blocks, in order to appoint Members of Diet to seats in the House of Representatives, the lower house of the National Diet of Japan. As the cabinet has to resign after a general House of Representatives election in the first post-election Diet session (Constitution, Article 70), the lower house election will also lead to a new designation election of the prime minister in the Diet, and the appointment of a new cabinet (even if the same ministers are re-appointed).
Generally, the retention referendum (formally kokumin shinsa, "popular review") to confirm judges of the Supreme Court who have been recently appointed or not confirmed for 10 years is held together with a lower house election.
Subnational elections scheduled for December 14 include the prefectural assembly election in Ibaraki. Another prefectural election in December 2014 is the gubernatorial election in Miyazaki, scheduled for December 21.
Under 2013 changes to the electoral law designed to reduce malapportionment, district boundaries in 17 prefectures have been redrawn and five districts are eliminated without replacement (one each in Fukui, Yamanashi, Tokushima, Kōchi and Saga). The number of first-past-the-post seats is reduced to 295, the total number of seats decreases to 475.
