The Southern Kantō proportional representation block (Hirei Minami-Kantō burokku (比例南関東ブロック)) is one of eleven proportional representation (PR) "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, and 22 representatives since the reapportionment of 2002.

Summary of results

With a district magnitude of 22, Southern Kantō is the second largest PR block behind Kinki and gives smaller parties an opportunity to pick up seats.
