Hokkaidō 8th district (北海道[第]8区) is a single-member electoral district for the House of Representatives, the lower house of the National Diet of Japan. It is located in the prefecture of Hokkaidō and consists of Hokkaido's Hiyama and Oshima subprefectures.

History

From 1947 the district was known as the Hokkaido 3rd district and elected three members to the House. Under the 1994 reforms that came into effect at the 1996 general election, the district's boundaries were not changed but it was renamed to the 8th district and had its representation reduced to one. This reduction was offset by the introduction of the multi-member Hokkaido proportional representation block that elects eight members to represent the entire prefecture.

Notes

^ The CDP is the successor party of the DP in this district, therefore the voting figures of the DP incumbent are used as a reference. Besides, Osaka run as an independent candidate because he announced so before the election. But he is able to be counted as a CDP candidate because he has joined CDP and was fielded by CDP after the election.
