List of members of the Diet of Japan

Template:Short description Template:Update Template:See also This is a list of members of the Diet of Japan. The Diet has two chambers: the House of Councillors (upper house) and the House of Representatives (lower house). Councillors serve six year terms, with half being elected every three years. Representatives serve terms of up to four years, but the House of Representatives can be dissolved, causing a shorter term (snap election).

House of Representatives

Below are lists of representatives elected in Japanese general elections since 2003.

• Members of the House of Representatives elected in the 43rd general election (2003)
• Members of the House of Representatives elected in the 44th general election (2005)
• Members of the House of Representatives elected in the 45th general election (2009)
• Members of the House of Representatives elected in the 46th general election (2012)
• Members of the House of Representatives elected in the 47th general election (2014)
• Members of the House of Representatives elected in the 48th general election (2017)
• Members of the House of Representatives elected in the 49th general election (2021)
• Current list: Members of the House of Representatives elected in the 50th general election (2024)

Composition

Notes:

• Not all members of a parliamentary group are necessarily members of the associated party/parties if any, and vice versa. For example, the Speaker and Vice-Speaker of the House of Representatives are independents in terms of parliamentary group membership, but not independents in terms of party membership.
• The count of terms as given by the House of Representatives follows the usual way of counting them in Japan by number of won elections (tōsen kaisū) which is not necessarily identical to election periods of the House of Representatives. For example, former member Nobutaka Machimura served for two terms as a member during the (2009–2012) 45th election period of the House of Representatives: one as member for the Hokkaidō proportional constituency from the general election in August 2009 to his resignation in September 2010, and one as member for constituency number 5 in Hokkaidō from the by-election in October 2010 to dissolution in November 2012. Among other things, the election count determines the seating within a parliamentary group, the more senior members by this measure sit in the back.
• Most proportional members of the House of Representatives have been deleted.

House of Councillors

Composition

List of members by parliamentary group and constituency. There are usually translations and abbreviations for parliamentary groups (会派 kaiha, current House of Councillors website translation: "In-House Group") used on the English pages of the House of Representatives website <ref>House of Councillors: Strength of the Political Groups in the House of Councillors</ref> The official caucus names<ref>List of caucuses Template:In lang</ref> are transcribed to Latin here:

• Template:Color box LDP
• Template:Color box Kōmeitō
• Template:Color box CDP
• Template:Color box DPFP
• Template:Color box Ishin
• Template:Color box JCP
• Template:Color box Reiwa
• Template:Color box SDP
• Template:Color box PPPNHK
• Template:Color box Independents

Notes:

• Not all members of a caucus are also members of the affiliated party, and sometimes even some members of a party are not member of the affiliated caucus.
• The N→S column allows to sort by prefecture from North to South in the order generally used in Japan (also used as number identifier for prefectures [JP-##] in ISO 3166-2).
• Due to a 2015 reapportionment, some districts are represented by an uneven number of members until the regular 2019 election, when it becomes effective in both halves.
