The 49th general election of members of the House of Representatives (Japanese: 第49回衆議院議員総選挙, Hepburn: dai-yonjūkyūkai Shūgiin giin sōsenkyo) is scheduled on or before 22 October 2021, as required by the Constitution of Japan. 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).

Election date[edit]

Under the post-occupation interpretation of Article 7 of the Constitution, the cabinet may instruct the Emperor to dissolve the House of Representatives before the end of term at will. Elections must be held within 40 days after dissolution.

The only time in postwar history that the House of Representatives was not dissolved before the end of its term was in 1976. If the House of Representatives completes a full four-year term, the election must be held within 30 days before that.[1]
