Next Japanese general election
The next Japanese general elections are scheduled on or before 31 October 2025, as required by the constitution. Voting will take place in all Representatives constituencies 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 election of the Prime Minister in the Diet, and the appointment of a new cabinet (even if the same ministers are re-appointed).
