General elections are scheduled to be held in Japan by 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).

The electoral districts will be readjusted according to the results of the 2020 Japan census. Originally, it was intended to be readjusted for the last election, but it was held in the existing constituencies not long after the census results came out.[2] [3]
Ten new districts and three new block seats will be created.
Ten districts and three block seats will be eliminated.
