List of constituencies for the Shūgiin
This is a list of the constituencies of the Shūgiin , the Japanese lower house, since the electoral reform of 1994 and their composition between 2003 and 2014. The single-mandate constituencies introduced with the reform have been in use since the 1996 Shūgiin election . Individual constituencies (in italics in the list ) were changed in 2002 (first used in the 2003 election): a total of 68 constituencies were re-cut in 20 prefectures, one constituency was added in five prefectures, one was deleted in each of five prefectures. Another change, decided in 2013, came into force in the 2014 Shūgiin election , but is not yet on the list; 42 constituencies in 17 prefectures were newly cut, five were deleted without replacement (one each in Fukui, Yamanashi, Tokushima, Kōchi and Saga), the number of seats in the direct electoral segment of the Shūgiin fell to 295. It is also not yet on the list another amendment adopted in June 2017, which will be applied for the first time in the 2017 Shūgiin election ; it changes 97 majority constituencies in 19 prefectures, including six that have been deleted without replacement (one each in the prefectures of Aomori, Iwate, Mie, Nara, Kumamoto and Kagoshima); in addition, four proportional representation blocks each lose one seat. The number of majority electoral seats drops to 289, the number of proportional representation seats to 176, a total of 465 members.
The list is grouped according to the regional “blocs”, the list constituencies for the proportional representation mandates introduced with the electoral reform. Between six and 29 additional MPs are appointed in each proportional representation block. The number of seats in the proportional representation blocks was changed three times: for the 2000 election, when the overall size of the proportional representation segment was reduced from 200 to 180 seats, and for the legislative changes in 2002 and 2017.
