# Yamanashi at-large district (House of Representatives)

The Yamanashi at-large district (Japanese: 山梨県全県区, Hepburn: Yamanashi-ken Zenken-ku) was a multi-member electoral district represented in the House of Representatives in the National Diet of Japan. From 1947 until 1993, it elected five representatives from Yamanashi Prefecture.

## History

In the 1947 Japanese general election, the Liberal Party and Japan Socialist Party won two seats each with Hisashi Amano, from the conservative Democratic, being the only candidate from other parties to win a seat. In the 1949 Japanese general election, all three conservative candidates retained their seats, and in the 1952 Japanese general election conservative candidates held three of the five seats.
After winning only two seats in the 1953 Japanese general election, they regained their majority in the 1955 Japanese general election by winning three seats, and in 1958 Japanese general election, the Liberal Democratic Party (LDP), which was formed from many of the conservative parties which had held seats in Yamanashi, won four out of five seats. Subsequently, the LDP and their conservative allies would win a majority of seats in every election afterwards until the district's dissolution. 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 [ja] came into law in 1950, the district encompassed the entirely of Yamanashi Prefecture.
Among the district's representatives were director-general of the Japan Defense Agency Shin Kanemaru, Minister of the Environment Sakihito Ozawa, and governor of Yamanashi Prefecture Shōmei Yokouchi.
