Class of 2022: Kagawa at-large district (香川県選挙区, Kagawa-ken Senkyo-ku) is a constituency of the House of Councillors in the Diet of Japan (national legislature).

It consists of Kagawa Prefecture and elects two Councillors, one every three years by a first-past-the-post system for a six-year term.

Kagawa in predominantly rural Shikoku has in most elections voted for candidates from the Liberal Democratic Party (LDP); but in 1950, 1965, 1971 and in the landslide election of 1989 – the first that led to a nejire kokkai ("twisted parliament": opposition control of the House of Councillors) – the main opposition Japan Socialist Party (JSP) managed to pick up a seat in Kagawa.

DPJ candidate Emiko Uematsu could win Kagawa by a large margin against LDP incumbent Kenji Manabe in the 2007 election that also led to a nejire kokkai.

When the opposition consolidated behind Miwako Oda in 2019, they lost by thirteen points to Miyake still.
