Shimane at-large district (House of Representatives)

The Shimane at-large district (島根県全県区) was an electoral district represented in the House of Representatives in the National Diet of Japan. From 1947 until 1993, it elected five representatives from Shimane Prefecture. Prime Minister Noboru Takeshita was elected to the seat in the last thirteen elections (out of eighteen) the district existed.

History
In the 1947 Japanese general election, for the only time in the district's history, left-leaning parties held a majority of the district's seats. However, conservative parties took a majority of the seats in the 1949 Japanese general election, and would continue to do so for the rest of the district's existence, including after the formation of the Liberal Democratic Party. Due to the 1994 Japanese electoral reform, the at-large district was replaced with three single-member districts starting with the 1996 Japanese general election.

At the time the Public Offices Election Law came into law in 1950, the district encompassed the entirely of Shimane Prefecture.

Among the district's representatives were Prime Minister Noboru Takeshita, who was elected to the seat in the last thirteen elections (out of eighteen) the district existed; House speakers Yoshio Sakurauchi and Hiroyuki Hosoda; and cabinet member Kozaemon Kimura.
