Types of Electoral Districts - TSV
Types of electoral districts are important elements in Japan's election system. Various electoral district systems exist, including single-member district system, multi-member district system, medium-sized district system, and proportional representation system, each with different characteristics and advantages/disadvantages. The House of Representatives adopts a parallel voting system combining single-member districts and proportional representation, while the House of Councillors combines district-based and proportional representation systems. These systems form the foundation of Japan's democracy.
