Southern Kanto proportional representation block
The Southern Kantō proportional representation block is one of eleven proportional representation "blocks", multi-member constituencies for the House of Representatives in the Diet of Japan. It consists of Southern parts of the Kantō region covering Chiba, Kanagawa and Yamanashi prefectures. Following the introduction of proportional voting it initially elected 23 representatives in the 1996 general election, then 21 after the total number of PR seats had been reduced from 200 to 180. After reapportionment in 2002 the number was increased to 22 representatives and again to 23 in 2022.
