Between 1947 and 1995 Kanagawa was represented by four Councillors. The 1994 electoral reform reapportioned the number of seats, increasing the number of Councillors in Miyagi, Saitama, Kanagawa and Gifu by two each (one per election) and reducing the number in Hokkaido, Hyogo and Fukuoka. Kanagawa, like most two-member districts, had often split seats between the two major parties, the Liberal Democratic Party (LDP) and the Japan Socialist Party (JSP). Following another reapportionment in the 2007 election when Tokyo gained an additional Councillor Kanagawa has the lowest electoral weight for the House of Councillors countrywide. As of September 2009, 7,301,452 voters were registered in Kanagawa.^[2]
