Definition
Gifu 3rd district is a single‑member constituency of the House of Representatives, the lower house of the National Diet of Japan. It elects one legislator by a first‑past‑the‑post (plurality) voting system.
Overview
The district is one of several electoral districts located within Gifu Prefecture, situated in the Chūbu region of central Honshū. It was created as part of the 1994 electoral reform that introduced a mixed-member majoritarian system, replacing the former multi‑member districts that had been used under the single non‑transferable vote (SNTV) system. Since its establishment, Gifu 3rd district has participated in all general elections for the House of Representatives, the most recent being the 2021 election.
Etymology/Origin
The name derives from the prefecture in which it lies—Gifu Prefecture—and its numerical designation as the third district within that prefecture. The numbering follows the order assigned by the Ministry of Internal Affairs and Communications when the 1994 redistricting plan was implemented.
